  3. 3. 1) IntroductionObjective• Introduce the key concepts of a business-rule driven architecture• Introduce the key concepts of E-LT• Understand what an Oracle Data Integrator (ODI) interface is• Through a business problem case study, understand and evaluate some differentdevelopment approaches including: • Manual coding • Traditional ETL • ODI’s business-rule driven approach combined with E-LTBusiness-Rules Driven ApproachIntroduction to Business rules: - Business rules specify mappings, filters, joins andconstraints. They often apply to metadata to transform data and are usually described innatural language by business users. In a typical data integration project (such as a DataWarehouse project), these rules are defined during the specification phase in documentswritten by business analysts in conjunction with project managers.Business Rules usually define “What” to do rather than “How” to do it. They can very often beimplemented using SQL expressions, provided that the metadata they refer to is known andqualified in a metadata repository.Examples of business rules are given in the table below: Business Rule Type SQL ExpressionSum of all amounts of items Mapping SUM(CASE WHEN SALES.YEARMONTH=2010/05sold during May 2010 THEN SALES.AMOUNT * PRODUCT.ITEM_PRICEmultiplied by the item price ELSE 0 END )Products that start with Filter Upper(PRODUCT.PRODUCT_NAME) like ‘CPU%’‘CPU’ and that belong to the And PRODUCT.CATEGORY = ‘HARDWARE’hardware categoryCustomers with their orders Join CUSTOMER.CUSTOMER_ID = ORDER.ORDER_IDand order lines And ORDER.ORDER_ID = ORDER_LINE.ORDER_IDReject duplicate Customer Unique CONSTRAINT CUST_NAME_PKnames Key PRIMARY KEY (CUSTOMER_NAME) Constraint Business Intelligence Solution Providers | 3
  4. 4. orders with a link to Reference CONSTRAINT CUSTOMER_FKan non-existent customer Constraint FOREIGN KEY (CUSTOMER_ID) REFERENCES CUSTOMER(CUSTOMER_ID)Mappings: A mapping is a business rule implemented as a SQL expression. It is atransformation rule that maps source columns (or fields) onto one of the target columns. Itcan be executed by a relational database server at run-time. This server can be the sourceserver (when possible), a middle tier server or the target server.Joins: A join operation links records in several data sets, such as tables or files. Joins are usedto link multiple sources. A join is implemented as a SQL expression linking the columns(fields) of two or more data sets.Joins can be defined regardless of the physical location of the source data sets involved. Forexample, a JMS queue can be joined to a relational table.Depending on the technology performing the join, it can be expressed as an inner join, rightouter join, left outer join and full outer join.Filters: A filter is an expression applied to source data sets columns. Only the recordsmatching this filter are processed by the data flow.Constraints: A constraint is an object that defines the rules enforced on data sets’ data. Aconstraint ensures the validity of the data in a given data set and the integrity of the data of amodel. Constraints on the target are used to check the validity of the data before integrationin the target.Traditional ETL versus E-LT Approach: Traditional ETL tools operate by first Extractingthe data from various sources, Transforming the data on a proprietary, middle-tier ETLengine, and then Loading the transformed data onto the target data warehouse or integrationserver. Hence the term “ETL” represents both the names and the order of the operationsperformed, as shown in Figure below.Understanding Oracle Data Integrator Interfaces : An interface is an ODI object stored in theODI Repository that enables the loading of one target datastore with data transformed from Business Intelligence Solution Providers | 4

Source Data is defined as a heterogeneous query on the CORRECTIONS file, the Storeand Region tables.A Business Problem case study: Figure describes an example of a business problem to extract,transform and load data from a Microsoft SQL Server database and a file into a target Oracletable.Data is coming from two Microsoft SQL Server tables (Store joined to Region) and. The targetSALES Oracle table must match some constraints such as the uniqueness of the ID column andvalid reference to the SALES_REP table.Data must be transformed and aggregated according to some mappings as shown in Figure Business Intelligence Solution Providers | 5
  6. 6. these business rules from natural language to SQL expressions is usuallystraightforward. In our example, the rules that appear in the figure could be translated asfollows: TYPE RULE SQLEXPRESSION/ CONSTRAINTFilter Only Store marked as Books STORE.store_type=’Books’Join A row from LINES has a matching ORDERS.ORDER_ID= LINES.ORDER_ID ORDER_ID in ORDERSMapping Target’s SALE is the sum of the order lines’ SUM(LINES.AMOUNT+ AMOUNT grouped by sales rep., with the CORRECTIONS.VALUE) corrections applied.Mapping Sales Rep = Sales Rep ID from ORDERS ORDERS.SALES_REP_IDConstraint ID must not be null ID is set to “not null” in the data modelConstraint ID must be unique A Primary Key is added to the data model with (ID) as set of columnsConstraint The Sales Rep. ID should exist in the Target A Reference (Foreign Key) is added in sales Rep table the data model on SALES.SALES_REP = SALES_REP.SALES_REP_IDWe will be looking at an organization that wishes to track sales from various heterogeneous datasources issued from the production systems. The following data sources will be used:The Repository: The Repository contains all of the metadata required for the training examples. Itis hosted, for these evaluation purposes, in a supplied database.Orders Application: An application for tracking customer orders, hosted in a supplied database(the "src_sales" sample database).Sales Administration: The administration or tracking of sales, hosted in another supplied database(the "trg_sales" sample database).

  9. 9. 2) Using ODI in your Data Warehouse ProjectIntroduction The main goal of a Data Warehouse is to consolidate and deliver accurateindicators to business users to help them make decisions regarding their everyday business. Atypical project is composed of several steps and milestones. Some of these are: • Defining business needs (Key Indicators) • Identifying source data that concerns key indicators; specifying business rules to transform source information into key indicators • Modeling the data structure of the target warehouse to store the key indicators • Populating the indicators by implementing business rules • Measuring the overall accuracy of the data by setting up data quality rules • Developing reports on key indicators • Making key indicators and metadata available to business users through ad-hoc query tools or predefined reports • Measuring business users’ satisfaction and adding/modifying key indicators.Organizing the Teams: As Oracle Data Integrator relies on a centralized repository,different types of users may need to access it. The list below describes how ODI may be usedby your teams. 1) PROFILE: Business UserDESCRIPTION: Business users have access to the final calculated key indicators throughreports or ad-hoc queries. In some cases, they need to understand what the definition of theindicators is, how they are calculated and when they were updated. Alternatively, they needto be aware of any data quality issue regarding the accuracy of their indicators.ODI MODULES USED: ODI Console 2) PROFILE: Business AnalystDESCRIPTION: Business Analysts define key indicators.They know the source applications and specify business rules to transform source data intomeaningful target indicators. They are in charge of maintaining translation data from operationalsemantics to the unified data warehouse semantic.ODI MODULES USED: Designer Navigator (limited access) ,ODI Console Business Intelligence Solution Providers | 9
  10. 10. 3) PROFILE: DeveloperDESCRIPTION: Developers are in charge of implementing the business rules in respect to thespecifications described by the Business Analysts. They release their work by providingexecutable scenarios to the production team. Developers must have both technical skillsregarding the infrastructure and business knowledge of the source applications.ODI MODULES USED: Limited access to Models Full access to Projects Operator Navigator ODIConsole 4) PROFILE: Metadata AdministratorDESCRIPTION: Metadata Administrators are in charge of reverse-engineering source andtarget applications. They guarantee the overall consistency of Metadata in the ODI Repository.They have an excellent knowledge of the structure of the sources and targets and they haveparticipated in the data modeling of key indicators. In conjunction with Business Analysts,they enrich the metadata by adding comments, descriptions and even integrity rules (such asconstraints). Metadata Administrators are responsible for version management.ODI MODULES USED: Topology Navigator (limited access), Designer Navigator: Full access toModels Restore access to Projects, ODI Console 5) PROFILE: Database AdministratorDESCRIPTION: Database Administrators are in charge of defining the technical databaseinfrastructure that supports ODI. They create the database profiles to let ODI access the data.They create separate schemas and databases to store the Staging Areas. They make theenvironments accessible by describing them in the TopologyODI MODULES USED: Topology Navigator (full access), Designer Navigator (full access), OperatorNavigator (full access), ODI Console 6) PROFILE: System AdministratorDESCRIPTION: System Administrators are in charge of maintaining technical resources andinfrastructure for the project. For example, they may install and monitor Scheduler Agents backup/ restore Repositories install and monitor ODI Console Setup environments (development, test,maintenance etc.)ODI MODULES USED: Agents, Topology Navigator (limited access), ODI Console 7) PROFILE: Security Administrator Business Intelligence Solution Providers | 10
  11. 11. The Security Administrator is in charge of defining the security policy for theODI Repository. He or she creates ODI users and grants them rights on models, projects andcontexts.ODI MODULES USED: Security Navigator (full access), Designer Navigator (read access), TopologyNavigator (read access), ODI Console 8) PROFILE: OperatorDESCRIPTION: Operators are in charge of importing released and tested scenarios into theproduction environment. They schedule the execution of these scenarios. They monitor executionlogs and restart failed sessions when needed.ODI MODULES USED: Operator Navigator ODI Console Oracle Enterprise Manager Plug-in For ODIThe ODI Master Repository contains built-in default profiles that can be assigned to users.
