1. Collibra Catalog

Collibra’s Data Dictionary documents an organization’s technical metadata and how it is used. It describes the structure of a piece of data, its relationship to other data, and its origin, format, and use. The solution serves as a searchable repository for users who need to understand how and where data is stored and how it can be used. Users can also document roles and responsibilities and utilize workflows to define and map data. Collibra is unique because the product was built with business end-users in mind.

5. AWS Glue Data Catalog

AWS Glue Data Catalog is the persistent metadata store in AWS Glue, a fully managed extract, transform, and load (ETL) service offered by AWS. The data catalog enables data management teams to store, annotate and share metadata for use in ETL integration jobs when they create data warehouses or data lakes on the AWS cloud platform. It supports similar functionality and is compatible with the megastore repository in Apache Hive, a popular open-source data warehouse tool. In some cases, organizations can also integrate the AWS data catalog as an external megastore for Hive data.

Users can share access to AWS Glue Data Catalog across an organization using their AWS Identity and Access Management (IAM) credentials. The data catalog tool helps enforce data governance requirements by tracking changes to schemas and data access controls. In addition, it supports data processes that span different AWS services, including AWS Lake Formation, Amazon Athena, Amazon Redshift, Amazon EMR, and more. AWS Glue Data Catalog can also be used to populate business data catalogs in Amazon DataZone, a separate data management service scheduled for a preview release in early 2023.

Other features offered by the AWS software include the following:

  • the ability to write scripts to automatically crawl repositories and capture information on schemas and data types;
  • improved visibility, control, and governance of data assets across various AWS data services; and
  • a settings page in the AWS Glue management console for changing permissions and other data catalog properties.

6. Apache Atlas

Apache Atlas is an open-source data governance and metadata management tool that allows businesses to collect, process, and maintain information more easily.

Why should you consider it?

Apache Atlas allows users to create and classify files, schemas, and tables, as well as to view data lineage through an intuitive user interface.

By enabling advanced data governance, the platform allows users to create new metadata types and instances and share metadata across teams through centralized analytics.
