Data warehouse designing process takes input from operational system of the organization. Quality
of data warehousing solution depends on design of operational system. Often, operational system
implementations of organizations have some limitations. Thus, we cannot proceed for data warehouse
designing so easily. In this paper, we have tried to investigate operational system of the organization for
identifying such limitations and determine role of operational system design in the process of data warehouse
design and implementation. We have worked out to find possible methods to handle such limitations and have
proposed techniques to get a quality data warehousing solution under such limitations. To make the work based
on live example, National Rural Health Mission (NRHM) Project has been taken. It is a national project of
health sector, managed by Indian Government across the country. The complex structure and high volume of
data makes it an ideal case for data warehouse implementation.
Data Warehouse Development Standardization Framework (DWDSF): A Way to Handle...IOSRjournaljce
Why does large number of data warehousing projects fail? How to avoid such failures? How to meet out user’s expectations and fulfil data analysis needs of business managers from data warehousing solutions? How to make data warehousing projects successful? These are some of the key questions before data warehouse research community in the present time. Literature shows that large numbers of data warehousing projects undertaken eventually result in a failure. In this paper, we have designed a framework named “Data Warehouse Development Standardization Framework” (DWDSF), to help data warehouse developer’s community in implementing effective data warehousing solutions. We have critically analysed literature to find out possible reasons of data warehouse project failure. Our framework has been designed to overcome such issues and enable implementation of successful data warehousing solutions. To verify usefulness of our framework, we have applied guidelines of DWDSF framework to design and implement data warehousing solution for National Rural Health Mission (NRHM) project which offers various health services throughout the country. The developed solution is giving results for all type of queries business managers want to run. We have shown results of some sample queries executed over the implemented data warehouse repository. All results are meeting out business manager’s query expectations.

Data warehousing solutions work as information base for large organizations to support their decision
making tasks. With the proven need of such solutions in current times, it is crucial to effectively design,
implement and utilize these solutions. Data warehouse (DW) implementation has been a challenge for the
organizations and the success rate of its implementation has been very low. To address these problems, we
have proposed a framework for developing effective data warehousing solutions. The framework is
primarily based on procedural aspect of data warehouse development and aims to standardize its process.
We first identified its components and then worked on them in depth to come up with the framework for
effective implementation of data warehousing projects. To verify effectiveness of the designed framework,
we worked on National Rural Health Mission (NRHM) project of Indian government and designed data
warehousing solution using the proposed framework.

Data warehouse generally contains both types of data i.e. historical & current data from various data sources. Data warehouse in world of computing can be defined as system created for analysis and reporting of these both types of data. These analysis report is then used by an organization to make decisions which helps them in their growth. Construction of data warehouse appears to be simple, collection of data from data sources into one place (after extraction, transform and loading). But construction involves several issues such as inconsistent data, logic conflicts, user acceptance, cost, quality, security, stake holder’s contradictions, REST alignment etc. These issues need to be overcome otherwise will lead to unfortunate consequences affecting the organization growth. Proposed model tries to solve these issues such as REST alignment, stake holder’s contradiction etc. by involving experts of various domains such as technical, analytical, decision makers, management representatives etc. during initialization phase to better understand the requirements and mapping these requirements to data sources during design phase of data warehouse.
Master data management (MDM) is defined as an application-independent process which describes, owns and manages core business data entities. The establishment of the MDM process is a Business Engineering (BE) tasks which requires organizational design. This paper reports on the results of a questionnaire survey among large enterprises aiming at delivering insight into what tasks and master data classes MDM organizations cover (“scope”) and how many people they employ (“size”). The nature of the study is descriptive, i.e. it allows for the identification of patterns and trends in organizing the MDM process.

A case study of using the hybrid model of scrum and six sigma in software dev...IJECEIAES
The world of software engineering is constantly discovering new ways that lead to an increase in team performance in the production of software products and, at the same time, brings the customer's further satisfaction. With the advent of agile methodologies in software development, these objectives have been considered more seriously by software teams and companies. Due to their very nature, agile methodologies have the potential to be integrated with other methodologies or specific managerial approaches defined in line with agility objectives. One of the cases is Six Sigma, which is used in organizations by focusing on organizational change and process improvement. In the present study, attempts were made to present the hybrid software development approach, including Scrum, as the most common agile and Six Sigma methodology. This approach was practically used in a case study, and the obtained results were analyzed. The results of this evaluation showed that this hybrid method could lead to the increased team performance and customer satisfaction. However, besides these two achievements, an increase in the number of re-works, number of defects discovered, and the duration of the project implementation were also observed. These cases are in line with the main objectives of Scrum and Six Sigma and are justifiable and acceptable due to achieving those objectives.

Abstract:
This presentation provides guidance to organizations considering or preparing for data quality initiatives. We will illustrate how organizations with chronic business challenges often can trace the root of the problem to poor data quality. Showing how data quality can be engineered provides a useful framework in which to develop an organizational approach. This in turn will allow organizations to more quickly identify data problems caused by structural issues versus practice-oriented defects. Participants will also learn the importance of practicing data quality engineering quantification.

This paper presents the method of mining the data and which contains the information about the large
information about the PR (Panchayat Raj Department) of Orissa .we have focused some of the techniques
,approaches and different methodology’s of the demand forecasting .Every organizations are operated in
different places of the country. Each place of operation may generate a huge amount of data. In an
organization, worker prediction is the difficult task of the manager. It is the complex process not only
because its nature of feature prediction but also various approaches methodologies always makes user
confused. This paper aims to deal with the problem selection process.In this paper we have used some of
the approaches from literatures are been introduced and analyzed to find its suitable organization and
situation, Based on this we have designed with automatic selection function to help users make a
prejudgment The information about each approach will be showed to users with examples to help
understanding. This system also provides calculation function to help users work out a predication result.
Generally the new developed system has a more comprehensive functions compared with existing ones .It
aims to improve the accuracy of demand forecasting by implementing the forecasting algorithm. While it is
still a decision support system with no ability of make the final judgment. .The data warehouse is used in
the significant business value by improving the effectiveness of managerial decision-making. In an
uncertain and highly competitive business environment, the value of strategic information systems such as
these are easily recognized however in today’s business environment, efficiency or speed is not the only
key for competitiveness. This type of huge amount of data’s are available in the form of tera- to peta-bytes
which has drastically changed in the areas of science and engineering. To analyze, manage and make a
decision of such type of huge amount of data we need techniques called the data mining which will
transforming in many fields. We have implemented the algorithms in JAVA technology. This paper provides
the prediction algorithm (Linear Regression, result which will helpful in the further research.
Successfully supporting managerial decision-making is critically dep.pdfanushasarees
Successfully supporting managerial decision-making is critically dependent upon the availability
of integrated, high quality information organized and presented in a timely and easily understood
manner. Data warehouses have emerged to meet this need. They serve as an integrated repository
for internal and external data—intelligence critical to understanding and evaluating the business
within its environmental context. With the addition of models, analytic tools, and user interfaces,
they have the potential to provide actionable information resources—business intelligence that
supports effective problem and opportunity identification, critical decision-making, and strategy
formulation, implementation, and evaluation. Four themes frame our analysis: integration,
implementation, intelligence, and innovation.
1:four major categories of business environment factors is
INTEGRATION,IMPLEMENTATION,INTELLIGENCE AND INNOVATION.
Organizations use data warehousing to support strategic and mission-critical applications. Data
deposited into the data warehouse must be transformed into information and knowledge and
appropriately disseminated to decision-makers within the organization and to critical partners in
various capacities within the organizational value chain. Crucial problems that must be addressed
in this area are: the modes of dissemination of information to the end user; the development,
selection, and implementation of appropriate models, analytic tools, and data mining tools; the
privacy and security of data; system performance; and adequate levels of training and support.
The human–computer interface is of paramount importance in the data warehouse environment
and the primary determinant of success from the end-user perspective. In order to support
analysis and reporting tasks, the data warehouse must have high quality data and make these data
accessible through intuitive interface technologies. Data warehouse browsing tools provide star-
schema query-like access through a flexible menu-based interface, with pull-down menus
representing important dimensions. These types of tools are easy to use and support some ad-hoc
exploration, but are usually controlled through an administrative layer that determines the data
available to endusers. In developing a flexible interface, there is a tradeoff between the ability to
express ad-hoc queries and the ease-of-use that results from pre-defined constructs implemented
by data warehouse designers and administrators. Of course, SQL can provide an ad-hoc query
facility, but its use requires some care in the data warehouse environment where the combination
of very large tables and ill-formed user queries can produce some truly awful performance and
potentially erroneous results. Casual users may not have sufficient understanding of SQL or of
the database schema to effectively use such an interface. Typically, only trained power users
(e.g., DBAs, application developers) are permitted to write SQL queries on .

As companies enter into the digital world, information technology is playing a major role in bringing
process improvements to the forefront of business management. In the recent decades, many organizations
have struggled to redesign and improve their business processes to reduce their total cost. The main
contribution of this research study is to propose an intelligent framework that possesses the ability to
employ a database of best practices, business standards, and business activity history in order to permit the
manager to analyze and improve the design of the business processes.
In addition, the other objective of this research is to build a business process or workflow directly from its
process design logic in order to enable rapid process development and deployment. This procedure
requires some technical improvements of the business design, as it is mainly based on building the business
process using Microsoft Office Visio, which communicates the defined business process to the business
process management engine.
ERP integrates business of an organization through a centralized database. The organizational data and transaction data are stored in the database. This data is a rich source of information. There are many software tools that would process the data and discover useful patterns. These techniques are referred to as data mining. The data from an ERP system may not be directly usable by data mining tools. The data may have to be pre-processed and made ready for data mining. A data warehouse is created from the ERP data that makes the data ready for data mining. An organization needs to interact with their suppliers for obtaining the raw material or semi-finished goods. They also need to interact with their retailers and dealers. These interactions may happen using EDI technology. Supply chain management (SCM) refers to managing suppliers and retailers. Customers are the reason why a business exists. The focus has changed from providing customer a product to providing a service built around the product. Customer relationship management (CRM) is the technology that helps an organization to manage its customers. CRM and SCM both integrate with ERP system and are collectively referred to as ERP-II.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Abstract: Data warehouse designing process takes input from operational system of the organization. Quality
of data warehousing solution depends on design of operational system. Often, operational system
implementations of organizations have some limitations. Thus, we cannot proceed for data warehouse
designing so easily. In this paper, we have tried to investigate operational system of the organization for
identifying such limitations and determine role of operational system design in the process of data warehouse
design and implementation. We have worked out to find possible methods to handle such limitations and have
proposed techniques to get a quality data warehousing solution under such limitations. To make the work based
on live example, National Rural Health Mission (NRHM) Project has been taken. It is a national project of
health sector, managed by Indian Government across the country. The complex structure and high volume of
data makes it an ideal case for data warehouse implementation.
Keywords: Data warehouse, Operational System, Dimensional Model, Atomic Data, NRHM
I. Introduction
With the exponential growth of data volumes in business organizations, and highly competitive
business environment, business organizations are looking for solutions that could provide them effective
business reporting not only for their short term business goals but also for long term strategic decision making.
Data warehousing solutions are highly useful in this direction and have been taken by the researchers as an
important area of research. Data warehouse designing process takes input from operational system of the
organization. For smooth and effective implementation of data warehousing solution it is necessary to have an
operational system in place. Quality of data warehousing solution depends on design of operational system.
Operational systems are capable of generating reports for monitoring and control of routine business operations,
but are not able to produce reports for strategic decision making. Often, operational system implementations of
organizations have some limitations. Thus, we cannot proceed for data warehouse designing so easily. We
have worked out to find possible methods to handle such limitations and have proposed techniques to get a
quality data warehousing solution under such limitations. We have taken National Rural Health Mission
(NRHM) Project for data warehousing solution implementation. It is a national project of health sector,
managed by Indian Government across the country. In the NRHM project, Business managers in different states
across the country want to analyze all the key operations, which require flexible reporting capabilities. When
we need to analyze a system for its long term performance and we also want to identify the favoring and non-
favoring factors in the fulfillment of organizational mission and objectives, we require a system which is
capable of generating reports useful for long term data analysis and decision making.
Operational system is a key component required for data warehouse implementation. Unlike
operational systems, data warehousing solutions are not mandatory but are useful in decision making process of
the organization. Standard data warehouse design techniques exist. If applied effectively, they result in quality
solutions. But, often the approach followed by the designers is not as per standards. It results in solutions that
have several drawbacks. It is one of the critical factors responsible for data warehousing system failure. Our
major focus is upon improving the methods of data warehouse development process. We have tried to explore
the measures required to be taken during data warehouse design and development. Using the techniques
identified here, one gets solution of the mentioned limitations and an effective data warehousing solution.
Organization of the paper is as follows: Section 2 gives literature review. Section 3 covers design
techniques for operational system and data warehousing system, followed by section 4 that describes NRHM
project, its goals and objective, operations, and key performance indicators. In section 5, we have discussed
limitations of NRHM operational systems. In section 6 we have proposed design techniques and practices to

deal with limitations of operational system and achieve effective data warehousing solution. Section 7 concludes
and specifies future scope.
II. Literature Review
There are many research areas in data warehousing where substantial research work has been done.
Still, further research is required because of continuous technological evolutions and changing user expectations
from these technologies. Major areas of research in the past on various aspects of data warehousing include
materialized view maintenance, query execution performance, modeling and design, integrated approach of data
warehouse design, Schema design, Data warehouse development process, effective maintenance,
standardization of data warehousing techniques, technical and managerial issues in data warehousing and many
others. Some of the areas that have received attention of research are clear from the given extracts.
Querying over Data Warehouse is much faster than traditional Relational DBMS. The performance
improvement is expected to be much higher as the size of the Dataset increases [1]. [2] has implemented Real
Time Data Warehouse framework. Their experimental analysis shows that if the delay comes from the
incremental maintenance of DMM, no ETL technology (full-reloading or incremental-loading) can help in real-
time business intelligence. Among all the I/O schedulers, the anticipatory scheduler should be avoided [3]. The
DW process, though supporting bottom-up extraction of information from data, fails in top-down enforcing the
company strategy. A new approach to BI, called Business Performance Management (BPM), is emerging from
this framework: it includes DW but it also requires a reactive component capable of monitoring the time-critical
operational processes to allow tactical and operational decision-makers to tune their actions according to the
company strategy. [4]. [5] discusses issues of slow-evolving fact, transaction-oriented fact table, large
dimensions and have proposed the concept of virtual data cubes and shown its usefulness. Active Data
Warehousing refers to a new trend where data warehouses are updated as frequently as possible, to
accommodate the high demands of users for fresh data [6]. Peer Data Management Systems (PDMSs) have been
proposed as architectures to support sharing of operational data across networks of peers while guaranteeing
peers’ autonomy, based on semantic mappings that mediate between the heterogeneous schemata exposed by
peers [8]. Data warehousing is an essential element of decision support. It aims at enabling the knowledge user
to make better and faster daily business decisions [7]. The process of data warehousing starts by analyzing
operational system of the organization. Incomplete and poor operational system design is bound to put hurdles
in smooth design and implementation of data warehousing solution [9].
Failure rate of data warehousing projects has been a major concern in data warehousing industry.
Prediction about data warehouse failure rate is clear from the statement of the Gartner’s research published in a
news article. According to STAMFORD, CONN February 24, 2005 — ―Data warehouses play a crucial role in
the success of a business intelligence (BI) program. However, through 2007, more than 50 percent of data
warehouse projects will have limited acceptance, or will be outright failures, as a result of a lack of attention to
data quality issues, according to Gartner, Inc.‖ [10]. Fewer than 30% of business intelligence projects meet the
objectives of the business, according to research from analyst Gartner [11]. To cater with such issues, we need
to investigate probable reasons of data warehousing project failure. Some of the apparent reasons for their
failure are that Data warehousing projects are costly and require long time periods for design and
implementations. Often data warehousing projects are neither given due weightage by all levels of management
nor are effectively utilized post implementation. Lack of user participation during design and development is
one of the major reasons for their failure. It is evident from the included references that usually the focus of
researchers has been on design and implementation of data warehousing solution without considering the
operational system design. Moreover, the high failure rate of data warehousing projects has also been a major
concern for the researchers. We have performed in depth investigation of operational system design and its
limitations and have focused mainly on the interaction with the client to determine their expectations from the
system to be developed.
III. Operational Systems
Operational systems are developed to smoothly run all business operations of the organization on
regular basis. These systems automate functioning of the organization. Objective of these systems is to help in
effective handling of daily business activities and ensure proper functioning of all the organizational operations.
Operational systems are mainly used by junior management to record details of daily business operations and to
enquire for information about a particular business operation held in the organization. Operational systems
usually handle one record at a time to extract its details. Major operations in operational system are regular
insertion/addition and updating of records. Reports are usually daily, weekly, monthly or quarterly that are used
to visualize various figures related to operations of the organization and are used to monitor execution of
business activities. Reports in such systems help in decision making about corrective measures for short term to
improve operational efficiency of the organization. Operational systems maintain atomic data for every business
3. Role of Operational System Design in Data Warehouse Implementation: Identifying…

transaction. Queries are mostly for individual records or list of records. Often, moderate aggregation is
performed on data to generate reports. Operational system usually maintains data for a period of one or two
years and transfers the older data to a separate data archival in order to save storage space and improve
performance of query execution. Operational system generates reports, based on only current data. It does not
generate historical reports.
3.1 Operational System Design
Operational systems are designed by taking inputs from different organizational vouchers, and
interacting with different user groups about data items they need to record for proper functioning of the
organization. Database schema for operational system is designed either by using ER- Modeling or
Normalization or combination of both. ER-modeling follows top down approach. In this approach the first step
is to identify all possible entity sets in the organization followed by determination of attributes of each entity set
in turn and declaring prime attribute and foreign keys on the basis of uniqueness property and cardinality of
relationship between any two entity sets respectively. ER modeling is effective in situations where
organizational documents and vouchers are not available and we need to design the schema by analyzing user
requirements from scratch. Design using normalization is done in the presence of some structured data of the
organization’s business operations. Normalization is based on the concept of functional dependencies and
suggests including only those dependencies in the tables where non prime attributes are dependent on prime
attribute. It also helps in enabling removal of multi valued dependencies from the tables. Fig. 1 shows a sample
ER-Diagram for one of the identified segment of NRHM project.
Fig1. ER Diagram for ANC Registration Process
3.2 Role of Operational System in data warehousing
Data warehouse schema is populated with the data from operational system of the organization and also
with the domain specific data from external sources. Data warehouse design involves cleaning, integration, and
transformation of operational system data. Complexity of these steps depends on quality of operational system.
Because of differences in objectives, and query requirements the data structure for both type of systems
is highly different. While operational systems are generally exposed to queries asking for non aggregated figures
for small time span for selected records, the nature of queries for data warehousing solutions are based on asking
highly aggregated figures for a large time span based on multiple parameters. Since inception of data takes place
with the transactions occurring in the organization that are recorded in the operational system. It is the same data
that needs to be transferred to data warehouse after cleaning and transforming into the form suitable for data
warehouse schema. If data quality of operational system is good it makes the population process of data
warehouse simple and fast otherwise the process of data warehouse population becomes complex.
Following are quality features identified in the operational system of the organization for implementation of data
warehousing.
i. Completeness: All required data items must be present in the operational system. Partial operational system
implementation would not facilitate effective data warehouse implementation.
ii. Minimum heterogeneity among multiple operational systems or their versions: Higher the heterogeneity
among multiple operational systems, higher the complexity of the cleaning process.
iii. Descriptive names of data items in the operational system, containing expected type and format of values.
iv. Availability of continuous data for past multiple years.

3.3 Data warehousing systems
Data warehousing is a process of accumulating vast amount of data from operational system of the
organization and some external sources depending on requirements and nature of the organization to create huge
data repository exposed to ad hoc business queries that produce required information within acceptable response
time [12]. Data warehouse systems are designed with an objective to analyze performance of the organization
required for strategic decision making. It includes high level data summarization and aggregation. These
systems are used to store and maintain data for years in a structure that is suitable for strategic reporting. These
systems have to deal with very large volume of data. Hence the issue of query execution performance arises,
which is resolved by keeping pre-aggregated intermediate query results. Data warehouse environment needs
extraction, transportation, transformation, and loading (ETL) solution, online analytical processing (OLAP),
data mining capabilities, client side analysis tools, and other data gathering tools to deliver useful reports to
business users.
Effectively designed, implemented and utilized data warehousing solutions would result in the growth
of the business organization backed up by informed decision making capabilities.
3.4 Data warehouse system design
Data warehouse designing is generally based on dimensional modeling which includes identification of
key business processes, facts to be measured, dimensions of analysis, and grain for measurement of facts
followed by designing multi dimensional star or snowflake schema depending on the nature of data and user
requirements. Fig. 2 shows example dimensional model for ANC registration process.

IV. National Rural Health Mission (Nrhm) Project
National Rural Health Mission (NRHM) is a project of Indian government that started in the year 2005
to provide quality health services throughout the nation under ministry of health and family welfare. Though,
the project runs with 17 different health programmes, major focus of NRHM has been on health care of mother
and child under Reproductive and Child Health (RCH). Due to lack of facilities in the large area of the country,
especially in the rural areas, government took initiative to establish infrastructure in the form of setting up
primary health centers and community health centers for providing health services at a very large scale. Major
objective of the RCH programme has been to improve statistics of mother mortality rate (MMR), infant
mortality rate (IMR), and total fertility rate (TFR). To monitor the progress and effectiveness of various health
programme, concept of hierarchical reporting from Primary Health Centre (PHC), Community Health Centre
(CHC), to District head quarters, state head quarters to state government and central government was formalized
specifying various monthly, quarterly, and annual reporting formats under Health management Information
System. Later for monitoring and management of Mother and Child health an online portal has been launched
called MCTS (Mother and Child Tracking System) that accepts inputs from PHCs, CHCs, District Hospitals,
and Sub District Hospitals at transaction level for the services these facility centres are providing.
To effectively analyze performance of various health facilities provided under NRHM project, with an
objective to get in depth analysis of factors responsible for lower performance as compared to the desired level.
The organization needs to develop a system that could generate various reports as per user
expectations. Process wise details of expected reports are given in the tables from 1 to 6.Many research
activities and surveys are conducted by programme managers and decision makers of NRHM project to find out
5. Role of Operational System Design in Data Warehouse Implementation: Identifying…
DOI: 10.9790/0661-17634452 www.iosrjournals.org 48 | Page
performance of programme execution, reasons for lesser performance in specific areas, and measures required to
be taken for improvement. Carrying out such surveys are costly affairs when conducted at national level. Instead
what we need is presence of such an operational system implementation and data warehousing solution at
national level so that need of such research activities are eliminated and replaced by an automated application
implementation that is capable for reporting such reports from within the application. It will save huge costs of
separate surveys/researches, time and efforts. The decision makers/ Programme managers will be benefited, if
they find the causes of lesser performance in order to provide type of intervention required in the project.
Similar data is being currently collected by various research activities conducted separately. Many
times the data is based on respondent’s interviews and is not so huge. Often data collected is based on various
sampling procedures. Huge data require financial burden and its collection is time taking also. Therefore
introducing above indicators in the data warehousing solution will give us facts about such a huge data and will
save from additional financial burden and will save time also.
4.1 Key Performance Indicators
Performance indicators are means of measuring quality of services provided and level of achievements
of a programme. NRHM project has taken infant mortality rate (IMR), maternal mortality rate (MMR), total
fertility rate (TFR) and morbidity and mortality rates as key performance indicators.The objective of NRHM is
to reduce maternal and infant mortality rates, total fertility rate (TFR) and morbidity and mortality rates. There
are many other identified performance indicators under various programmes but we have mentioned the
performance indicators related to the mother and child health care as it is highly focused segment of the NRHM
project.

population of about 1.25 billion. To ensure true representation of the whole population in terms of various health
facilities provided across the country, three different states namely Uttar Pradesh, Rajasthan, and Madhya
7. Role of Operational System Design in Data Warehouse Implementation: Identifying…
DOI: 10.9790/0661-17634452 www.iosrjournals.org 50 | Page
Pradesh were chosen for interaction with the business managers/ user groups to ensure comprehensive
investigation and getting truly representing requirements. Methods applied for analysis of user requirements and
finding out user expectations from the data warehousing solutions include:
1. Reference of organizational documents like NRHM Journey so far, Monitoring and Evaluation, Family
welfare statics 2011, Directory of Innovations Implemented in the Health Sector, Health programme manager’s
manual, Integrated MIS reporting etc. to know organizational goals and objectives, mode of functioning and
current reporting abilities and user’s expectations from data warehousing solution.
2. Personal interaction with the business managers of the organizations at various levels in the organizational
hierarchy like CMOs, Dy. CMOs, DPMs, DEO, HEOs, Nodal Officers, BAO, Statistical officer, Data Entry
Operator.
3. Circulation of questionnaire and collection of response from various user groups in the organization.
4. Exploration of national and state level websites of NRHM maintained by central and state governments
respectively.
Following steps were taken to start data warehouse designing for NRHM project and identify designing
techniques required to overcome limitations of the existing operational system.
1. Investigation of operational system to assess its design quality.
2. Identification of operational system design limitations.
3. Investigation of reporting capabilities of operational system.
4. Determination of level of dependability on these reports
5. Identification of design techniques to overcome limitations of operational system.
4.2.1 Design of Questionnaire
For identification of user requirements and the kind of problems they have been facing with the current
system, a Questionnaire was designed and circulated among various user groups of the system. The
questionnaire covers questions mainly of the following categories:
What measurements you want to make? What are parameters on which you want to analyze these
measurements? What strategic decisions you are required to make on the basis of above measurements? How
would these measurements help in taking strategic decision making?
Which is most important time dimension in your domain of analysis? What are other important time
dimensions? What type of reporting formats required?
V. Limitations Of Nrhm Operational System
By applying the steps and methods of investigation during analysis of operational system design with
an objective to design data warehousing solution, some limitations were found in the operational system of the
NRHM project. We have briefly summarized the identified limitations point wise.
i. All data items required for performance evaluation are not present in the operational system. ii. Presence of
multiple isolated applications across different states resulting in heterogeneity.
iii. Many applications are partially implemented.
iv. Data submission from facility centres is not regular.
v. Some of the centres never submit data resulting incomplete data.
vi. Aggregated Data submission formats diminishing scope for drill down details.
vii. Non-uniform grain of data submission from different centres up in the hierarchy.
viii. The cases not availing the facilities from NRHM are not considered
VI. Techniques For Dealing With Operational System Design Limitations
Presence of identified limitations in the operational system hampers design and implementation of data
warehousing solution. It is important to find out methods to deal with such limitations so that one can proceed
for data warehousing system design and implementation with the assurance of quality solution even in the
presence of these limitations. In this section we have discussed each of the identified limitation and its solution.
i. Non comprehensive consideration of data items in the operational system is a critical limitation. A simple
technique to deal with such problem includes identification of data items that are important but have not been
considered in the operational system. We then explore and find out the reason for its non consideration. If there
is a justified valid reason then we need to find an alternate solution. Assessment of its requirement for data
warehousing solution is to be done. If it is found to be an important and required data item for data warehousing
solution, we need to make provision for its entry into data warehousing system. A practical approach of
investigating all data entry forms in the operational system was followed, with an objective to determine list of
data items that have provision for input and also the list of data items that are not entered into the system, but are
required for generating reports as per user’s expectations. Problem occurs when a particular data item has not

been considered just due to casual design approach during the operational system design. We can represent the
solution for the problem of unavailability of required data items in the following pseudo code solution:
For all forms i= 1 to n
Check forms[i]
Make a list of data items on the form and name it list 1
Check the users reporting expectations related to the form under consideration
Make a list of data items required and name it List2
If (List2 is subset of list1)
Form[i] is complete
Else
(list2-list1) items are missing and need to be considered.
ii. Presence of multiple isolated applications running in the organization that are not integrated with each other:
The approach used that could identify such problem in the operation system was interaction with the client
organization by means of questionnaire and personal interaction. Business users revealed that there is not a
single integrated system across all states, all states have got different operational systems developed tailor made
to their local needs. First step of solution for such problem is to plan and execute migration of multiple
operational systems of the organization to a single integrated application. Next, the ETL procedure needs to be
written to transform data from all the existing operational systems in the data warehouse then design ETL for
the integrated operational system.
iii. Incomplete or partial implementation of the functionalities: upon investigation of different operational
systems in use, it was found that all operational systems were not having all the required functionalities.
Solution for such problem is to first identify the functional modules that have not been implemented
but are actually required. We also need to investigate functionality of the existing functional modules to
determine if they are complete. Accordingly new modules or additional code in the existing modules can be
added in the operational system.
iv. Incomplete or partial submission of data in the operational system from different facility centers:
Identification of such problems in the system is possible by investigating the data submitted by different centres
with the objective to check their completeness. Two fold solution for this problem needs to be implemented.
We need to incorporate feature in operational system to report at pre-specified time intervals about
details of non execution of data submission by different facility centers. We also need to develop and
communicate among the concerned staff, about the business process protocols to ensure that action is taken on
defaults on part of data submission and compulsion is enforced for execution of submission of data.
v. Non submission of data by the centres is similar to partial submission of data and could be resolved in the
same way.
vi. Aggregated data submission formats have been taken in HMIS based formats which is not an online
application but is a reporting facility for the work executed during a specified time interval like month, quarter,
or a year. If aggregated data figures are reported, details cannot be extracted from the data because of loss of
details due to aggregation. The solution for this problem is possible by way of implementation of an online
application with the provisions of recording atomic level data items against facilities being provided at each of
the facility centre.
vii. Variable grain across different reporting centres up in the hierarchy: The solution to the problem of varying
level of grain is similar to the solution for aggregated data reporting. Solution to this problem is possible by
implementation of an online application with the provisions of recording atomic level data items against
facilities being provided at each of the facility centre.
viii. For cases not availing the facilities from the NRHM affiliated centres, a separate survey needs to be
conducted for collection of required data. Such data then needs to be fed into the system and them loaded into
data warehousing solution. An interface could be developed in the operational system to facilitate the centres not
affiliated to NRHM to directly upload data eliminating need of additional surveys.
