Businesses of all sizes are dealing with vast amounts of data generated from various sources. The challenge is – how to manage and utilize this data to make informed decisions and gain a competitive edge. Enter the data catalog – a modern data management solution for new-age organizations.  

This blog piece will some important concepts around data catalogs that businesses must know in 2023:  

      • Meaning of data catalog  
      • Its importance  
      • Data catalog use cases  

What is a data catalog?

A data catalog is defined as a specialized tool/application that helps organizations identify, understand, assess, and organize their data assets.  

Let’s try to understand the concept with the help of an example. Think of data catalog as a travel itinerary. The itinerary acts like a catalog as it provides detailed information about your travel plan such as sightseeing spots, local cuisine, transportation options, accommodation details, and more. It helps you quickly comprehend what options are available, discover new places, and make informed choices about what places to visit or what activities to opt for. In the same way, a data catalog helps businesses quickly discover valuable datasets, identify and understand available data assets, and make informed decisions about which data to leverage for different business purposes 

By providing insights into data quality, ownership, access controls, and data usage, data catalogs help streamline data management and governance. With the availability of detailed metadata, enterprises can easily identify responsible entities for each dataset, enabling accountability and adherence to data governance standards and guidelines.  

Informatica’s enterprise data catalog enables organizations to get a clear view of their most relevant data. It supports data discovery via an intuitive interface and helps gain contextual insights from data lineage and profiling. Businesses can leverage AI-powered domain discovery, data similarity, and more.  

Data Catalogs: What they are not

Many individuals mistake a data catalog for a data warehouse, data dictionary, and business glossary. All of them are concepts of data management but serve different objectives. Let’s take a look at them one by one:  

 

Data warehouse – While both data warehouse and data catalog are repositories of information, they have different functionalities. A data warehouse consolidates and stores structured data from various sources for analysis and reporting, while the data catalog offers information about the data assets available in the data warehouse and other data sources.  

 

Data dictionary – Data dictionary offers technical documentation about the data elements such as data type, format, and so on. A data catalog goes beyond the capabilities of a data dictionary. It captures information about data usage, data relationships, and data lineage.  

 

Business glossary – A business glossary is a compilation of business terms and their definitions. It is a single source for commonly used business terms and ensures a consistent understanding of terminologies across an organization. A data catalog focuses specifically on data assets, attributes, and their meanings. It connects business terms to corresponding data elements.
