Active Metadata Management

By Kalyana Chakravarthy Yellapragada

Data offers the promise of many benefits, from profits to efficiency, but in order to realize these benefits, it must be understood and managed. The growth of data of all kinds is exponential, and surpassing an organization’s ability to manage it. Data has universally been recognized in recent years as a valuable asset as well. It has great potential to maximize efficiency, pinpoint new opportunities, and report on the status of mission goals. However, as such, it requires management and tracking, just like other assets.


Data Catalog, which is an automated inventory of data assets, augmented (powered) by machine learning (AI/ML). Data Catalog enables users to discover and explore all the data sources available, enhancing their understanding of these sources, enabling collaboration with other users to enrich the quality of the assets, and achieving more value from the organization’s data.

Industry scenario or Technology evolution What is Data Catalog

Data Catalogs promote intelligent and secure data sharing by centralizing, labelling, and monitoring your organization’s data assets. This single control plane allows for better collaboration, stronger regulatory compliance, and reduced overhead.

What Data Catalog Contains

  • A single source of the truth for the enterprise.
  • Ability to find new data sources monetize Data elements
  • Knowledge Graphs
  • Data Lineage
  • Impact Analysis
  • User Data Monitoring and Auditing the Data Lineage
  • Role-based access control to ensure Data Security
  • Opensource/COTS-On-premise/CLOUD based solutions
  • Integration with the Data Governance

Industry Scenarios

  • Data Usage: Who is using the Data and What is the purpose of using the Data?
  • Data Greenness: Are we using the most up-to-date version of the data we need?
  • Data Security: How do I restrict permissions so that access to data is controlled to only certain rows and columns? Can I grant limited or read-only access easily?
  • Data Overhead: Is there another department in this organization that could use the same data? Is there a way for me to find out if we’re already buying it?
  • Data Redundancies: Are there different departments doing similar work on the same data?
  • Data Discrepancies: How can we link all of the data we have to ensure we’re conforming to the same standards across our whole organization?

Business needs in focus

Data Catalog addresses a variety of business needs. The following are some of them

  • Data Lake modernization: Enterprises store various source systems Data into Data Lake in raw format with minimal metadata information, so it is difficult for the users to identify, understand and access the Data. To overcome this situation Data Catalog on the top of Data Lake would provide desirable information to the users like Business Analysts, Data scientists etc.
  • Cloud Modernization: Many Enterprises are moving towards Cloud Infra and services. Data Catalog provides the visibility of Data across on-premise, Cloud, and Hybrid environments. In addition, data Catalog data lineage provides involved source and target information and ensures that it won't be any data lost during cloud migration and Integration. Data Catalog supports for the Cloud spend analysis based on source data so users can make appropriate decisions related to cost comparison
  • Data Democratization: In Enterprises, Data is spread across multiple departments and stored in different systems. As a result, it is challenging to organize, maintain and utilize the data effectively and efficiently. Data Catalog provides reliable, predefined and pre-approved data. In addition, systems do not need to wait for the required datasets, and it contains a streamlined approval process to utilize any Datasets. This process increases productivity and reduces the timelines to search for the datasets to spread and analyze the findings.
  • Discovering Sensitive Data: Data Catalog supports discovering sensitive data where business doesn’t know the existence of sensitive data objects, which are compliance with PII, GDPR, etc.

Technology Ecosystem, Products and Platforms

There are many products in the industry that supports Data Catalog. Some of them are Data.World, Informatica, Collibra, Alation, etc.
