Data observability is a collection of technologies and activities that allows data science teams to prevent problems from becoming severe business issues.
Now companies are in the middle of a renovation that forces them to be analytics-driven to
continue being competitive. Data analysis provides a complete insight about their business. It
also gives noteworthy advantages over their competitors. Analytics-driven insights compel
businesses to take action on service innovation, enhance client experience, detect irregularities in
process and provide extra time for product or service marketing. To work on analytics driven
activities, companies require to gather, analyse and store information from all possible sources.
Companies should bring appropriate tools and workflows in practice to analyse data rapidly and
unceasingly. They should obtain insight from data analysis result and make changes in their
business process and practice on the basis of gained result. It would help to be more agile than
their previous process and function.

Over-running volume of data is a problem that should be addressed by data management and storage management. Data is being constantly collected but poorly analyzed which leads to excessive amounts of data occupying storage and delay in operations which inevitably affect production, sales and profits. If this remains unresolved, current data may have to be moved to external storage and recovered if needed. There is also the risk of data not being encoded into computers and thus will remain in manual state. This can be a case of redundant or extraneous data that is not yet cleaned and normalized by operations managers with the guidance of IT. This situation is known as data overload where companies actually use only a fraction of the data they capture and store. Many companies simply hoard data to make sure that they are readily available when they are needed. This negatively impacts the Corporation when assessing data relevance, accuracies and timeliness (Marr, 2016).

The Largo Corporation (LC) seems to running on an enterprise resource planning system that is probably as long as 20 years old. Initially, LC has had success with the old system because they were able to establish themselves in various industries such as healthcare, media, government, etc. But due to various concerns, the Corporation is currently running on an outdated system because it is unable to provide services that keeps the Corporation a float. The LC is losing revenue and customers. Complete data without analysis is invaluable because, no information and insights can be produced that will support decisions. Customer data should lead to the best marketing and sales campaigns. The Corporation needs to recognize its weaknesses and implement changes to their software by incorporating funding for a new system that is reliable, secure, and has the ability to run on integrated systems; all of which will streamline data organization and analysis for the enterprise. (Rouse, n.d).
Network/Telecommunications
The network that was built in the 1980’s has become slow and unreliable affecting business operations. The problems caused by the old network are; lack of integration and communication between departments affecting the work flow, supply vs. demand, and inability to analyze data to carry out these operations. The Corporation should have taken into consideration the growth of the company by expanding and upgrading their networks along with their services. They should also take into consideration the number of departments, the number of users and their skill level, storage and bandwidth, and budget (Rasmussen, 2011). The current network does not allow employees to connect on their mobile devices which restricts flexibility and places limitations on productivity and portability.

DATA VIRTUALIZATION FOR DECISION MAKING IN BIG DATAijseajournal
Data analytics and Business Intelligence (BI) are essential components of decision support technologies that gather and analyze data for faster and better strategic and operational decision making in an organization. Data analytics emphasizes on algorithms to control the relationship between data offering insights. The major difference between BI and analytics is that analytics has predictive competence which helps in making future predictions whereas Business Intelligence helps in informed decision-making built on the analysis of past data. Business Intelligence solutions are among the most valued data management tools whose main objective is to enable interactive access to real-time data, manipulation of data and provide business organizations with appropriate analysis. Business Intelligence solutions leverage software and services to collect and transform raw data into useful information that enable more informed and quality business decisions regarding customers, market competitors, internal operations and so on. Data needs to be integrated from disparate sources in order to derive valuable insights. Extract-Transform-Load (ETL), which are traditionally employed by organizations help in extracting data from different sources, transforming and aggregating and finally loading large volume of data into warehouses. Recently Data virtualization has been used to speed up the data integration process. Data virtualization and ETL often serve unique and complementary purposes in performing complex, multi-pass data transformation and cleansing operations, and bulk loading the data into a target data store.

Data Observability- The Next Frontier of Data Engineering Pdf.pdf
1. With numerous data products relying on hundreds and thousands of external
and internal data sources, modern organizations now have a more significant
number of data use cases. To meet their growing data needs, they have
adopted advanced technologies and big data infrastructures.
The increasing complexity of the data stack, the sheer volume, variety, speed,
and quantity of data generated and collected, opens the door to more complex
issues like schema changes, random drifts or poor data quality, downtimes,
duplicate data, and other complex issues. The complexity of data
management is also exacerbated by the many data storage options, data
pipelines and an array of enterprise applications.
Data engineers and business executives responsible for maintaining and
building data infrastructures and systems are often overwhelmed. They do
their best to keep data systems functional and operational as much as
possible. There are no perfect systems, and data volumes can be
unpredictable. No matter how much money data teams have invested in the
cloud, how sophisticated an analytics dashboard is or how well-designed it is,
everything fails--if unreliable data is ingested, transformed, and pushed
downstream.
Modern data pipelines are interconnected and not intuitive. Because of this,
data from both internal and external sources can become inconsistent,
inaccurate, missing, or change suddenly, which could eventually impact the
correctness and accuracy of dependent data assets. Data and analytics teams
must be able to dig deep to find the root cause of any data issues and then
resolve them.
It isn't easy to achieve this without a comprehensive and complete view of the
entire data stack and its lifecycle. Data observability is valuable for data teams
and organizations to ensure data quality and a reliable data flow throughout
their day-to-day business operations.
Data observability is essential, organizations and teams should pay attention
to it in order to achieve their data-driven visions.
What is Data Observability?
While observability is most commonly used in engineering and software
systems, it is also essential in the data niche. Software engineers can monitor
the health and performance of their applications using tools like DataDog,
AppDynamics and NewRelic -- data teams must also do the same.
2. Data observability is the ability of an organization to keep a constant pulse on
their data systems through tracking, monitoring and troubleshooting issues to
reduce downtime, improve data quality, and eventually prevent issues from
happening.
It is also a collection of technologies and activities that allow data and
analytics teams to track data-related failures and walk upstream to determine
what is wrong at each level (quality, infrastructure, and computation). This
helps data teams to measure the operative and effective use of data and
understand what’s happening across every stage of the enterprise data life-
cycle.
Similar to the three pillars of observability, data observability has 5 pillars.
Each pillar answers a series of questions that allow data teams to get a
holistic view of data health and pipelines when they are combined and
continuously monitored. Let’s have a look at these questions:
Freshness: Was all data received and is it current? What
upstream data was omitted/included? When was the last time
data was extracted/generated? Was the data received on time?
Volume: Has all the data been received? Are all the data tables
complete?
Distribution: To whom was the data sent? How useful and
complete is the data? Is the data reliable? What was the process
of transforming the data? Are the data values within an
acceptable range of value?
Lineage: Who are the downstream ingesters of a data asset?
Who generates the data? Who will use the data to make business
decisions? What are the stages at which downstream ingesters
will use the data?
Schema: Does the data format conform to the schema? What has
changed in the data schema? Who made the changes?
What Is the Importance of Data Observability?
Data observability goes beyond monitoring and alerting. It allows
organizations to understand their data systems fully and allows them to fix or
even prevent data problems in increasingly complex data situations.
3. 1) Data observability increases trust in data so that businesses can
make data-driven business decisions confidently.
While data insights and machine-learning algorithms can be invaluable,
inaccurate or mismanaged data can have devastating consequences.
Public Health England (PHE), which tracks daily Covid-19 infection rates,
found an error in their data collection. This error caused 15,841 cases
between September 25 and October 2 to be overlooked. According to the
PHE, the Excel spreadsheet used to collect data exceeded its data limit. The
result was that the daily number of new cases was much higher than initially
reported. Tens of thousands of people who had tested positive for Covid-19
did not receive contact from the government's "test & trace" program. Data
observability allows organizations to track and monitor situations efficiently
and quickly. This allows them to make more informed decisions.
2) Data observability allows for the timely delivery of high-quality data to
support business workloads.
Every organization must ensure that data is easily accessible and in the
correct format. Almost every department in an organization relies on high-
quality data for business operations. Data scientists, data engineers, and data
analysts depend on the data to provide insights and analytics. A lack of quality
data can lead to costly business process breakdowns.
For example, your company has an ecommerce site with multiple data
sources (stock quantities, sales transactions, user analytics), which
consolidate into a data warehouse. To generate annual reports, the sales
department requires sales transaction data, the marketing department relies
on user analytics data to run effective marketing campaigns and data
scientists rely on data to build and deploy machine learning models that will
help them recommend products. It could cause harm to the various aspects of
the business if one of the data sources is incorrect or out of sync.
Data observability is a way to ensure the quality, reliability, and consistency of
data within the data pipeline. It gives organizations a 360-degree overview of
their data ecosystem. This allows them to drill down and fix any issues that
could disrupt their data pipeline.
3) Data observability allows you to identify and fix data issues before
they affect your business.
4. Pure monitoring systems have a significant flaw that they can only detect
unusual conditions or situations you know about or anticipate. But what about
those cases that you can't see coming?
A mistake caused by Amsterdam's City Council in 2014 led to the loss of
EUR188 million. Inadvertently, the error occurred because the software used
by the council to distribute housing benefits to low-income families was
programmed in cents rather than euros. Families received significantly more
than they anticipated due to the software error. People who were expected to
receive EUR155 received EUR15,500. Even more alarming is that
administrators were not notified of this error by the software.
Data observability can detect situations you don't know about or wouldn't
consider looking for. It can also prevent problems from becoming severe
business issues. Data observability allows you to track the relationships
between specific issues and provides context and pertinent information for
root cause analysis.
Top Data Observability Platforms for Monitoring Data
Quality at Scale
We understand how difficult it can be to find the right observability tool for your

10) Soda
Soda's AI-powered platform for data observability is an environment that
allows data owners, engineers, and data analysts to work together to solve
problems. Soda.ai describes the technology as "a platform that enables teams
to define what good data looks like and handle errors quickly before they have
a downstream impact." This tool allow users to examine their data and create
rules to validate it quickly.
Implementation of a Data Observability Framework
Data observability is an "outcome" of the DataOps movement. Even though
you can have the most advanced automation and algorithms to monitor your
metadata, it will only benefit with organizational adoption. However, anyone
can adopt DataOps as an organization, but it will be a well-documented
philosophy that doesn't impact output without the technology to support it.
So, how do you implement a data observability framework that improves your
data quality at all levels? What metrics should be tracked at each stage of the
data observability framework?
These are the key ingredients for a highly-functional data observability
framework:
7. i) DataOps Culture
ii) Standardized Data platform
iii) Unified Data Observability Platform
Before you can even consider producing high-value data products, you must
have widespread adoption of the DataOps Culture. This requires everyone to
be involved, especially leadership. They will be the ones who create the
systems and processes that support development, maintenance, feedback,
and other activities. A bottom-up movement is powerful, but you still need
budget approvals to make the necessary technological changes to support
DataOps.
Leadership can help the organization move towards a standardized data
platform if everyone buys into the idea. What does this mean? To ensure that
all teams have end-to-end accountability and ownership, infrastructure must
be in place to allow them to communicate openly and speak the same
language. Standard libraries are needed for API and data management (i.e.,
querying the data warehouse, reading/writing to the data lake, pulling
information from APIs, etc.) A standardized library is also required to ensure
data quality along with source code tracking, data versioning, and CI/CD
processes. With all this in place, your infrastructure is ready for success.
You now need an open, unified platform for monitoring your system's health
that allows your entire organization to access it. The observability platform will
act as a central metadata repository. It would include all of the features
mentioned earlier (like monitoring and alerting, tracking, comparison and
analysis), so data teams could view how other platform sections affect them.
To effectively monitor the functioning of the Data Observability Framework,
you should monitor the following metrics:
1) Operational Health:
Execution Metadata
Pipeline State
Delays
2) Dataset Monitoring:
Availability
Freshness
8. Volume
Schema Change
3) Column-level Profiling:
Summary statistics
Anomaly detection
4) Row-level Validation:
Business rule enforcement
Stop "bad data"
To ensure operational health, it's best to collect execution metadata. This
metadata includes information about pipeline states, length, delays, retries,
and the times between runs. You should monitor the completeness and
availability of your data along with the volume and changes to the schema.
You should collect summary statistics for columns and use anomaly detection
to alert you of any changes. The column trends would include the Mean, Max,
and Min. Row-level validation would require you to ensure that previous
checks were valid and adhered to your business rules. This is very contextual,
so you will need to exercise your discretion.
Conclusion
Data observability is essential for any data team to be agile and iterate quickly
on their products. Without data observability it's difficult for teams to rely on
their infrastructure or tools because errors can't be tracked quickly. This
results in less flexibility in developing new features or improvements for
customers. You're effectively wasting money if you are not investing in this
critical piece of the DataOps framework in 2022.
