A data catalog is an assortment of metadata, together with storage and search capabilities, that aids analysts and other users of data in finding the data they want, acts as a list of the data that is currently accessible, and offers information to assess the suitability of the data for the purposes for which it is being used.

Data administration, searching, information inventory, and data assessment are among the points made regarding data catalogs in this succinct description. However, they are all reliant on the basic capacity to give a collection of information.

In the era of big information and self-service business intelligence, data catalogs have established themselves as the industry standard for managing metadata. The metadata we require now is bigger than the metadata from the BI era. In order to enlighten individuals who deal with data, a data catalog first concentrates on datasets (the inventory of readily accessible data).

The files and tables that data workers must locate and access are known as datasets. They might be kept in a master data repository, data lake, warehouse, or any other shared data resource. Data workers such as consumers, curators, stewards, subject matter experts, etc. are all described by people metadata. To assist users in finding data, search metadata includes tagging and keywords.

The application of transformations and derivations as data is handled throughout its lifespan is described by processing metadata. Supplier metadata, which provides information about sources and subscription or license restrictions, is particularly crucial for data obtained from external sources.

The essential capacity of cataloging data—collecting the information that identifies and characterizes the inventory of shareable data—underlies all of the features and functionalities that a contemporary data catalog provides. Cataloging cannot be attempted manually due to practical reasons. The initial catalog development and continuing discovery of new datasets both need automated dataset discovery. In order to maximize the benefits of automation and reduce human work, it is crucial to use machine learning and artificial intelligence for metadata collecting, semantic inference, and tagging.

Numerous more capabilities and functionalities are provided by the data catalog’s strong metadata, the most crucial of which are:

  • Searching a Dataset: Powerful search options include searching by facets, keywords, and business phrases. For non-technical consumers, language-based search capabilities are extremely useful. Particularly helpful and advantageous aspects are the ranking of search results by relevancy and frequency of usage.
  • Dataset Evaluation: Without having to download or collect data beforehand, it is possible to determine which datasets are best for a certain analysis use case. The ability to preview a dataset, examine all related metadata, view user ratings, read feedback from users and curator annotations, and check data quality information are all crucial assessment elements.
  • Data Access—The user experience should be smooth along the process from search to evaluation to data access, with the catalog understanding access protocols and either directly granting access or collaborating with access technologies. Access safeguards for sensitive data related to security, privacy, and compliance are included in data access functions.

In addition to these functions, a strong data catalog software should allow data curation and cooperative data management, track data consumption, provide intelligent dataset suggestions, and offer a wide range of data governance tools.

By considering the value of data and the abilities that are produced with full information, the advantages of a data catalog for data management become clear.

However, the influence on analytical tasks is frequently where the most value may be found. We live and operate in a self-service analytics era. The growing number of individuals who study data cannot be served by IT firms with all the information they require.

However, today’s business and data analysts frequently operate in the dark, without knowledge of the available datasets, their contents, and the caliber and value of each. They take too long to locate and comprehend data, sometimes re-creating datasets that already exist. They typically use poor datasets, which leads to analysis that is poor and erroneous.

Without a catalog, analysts search for data by reading through documents, speaking with coworkers, relying on lore, or just using well-known datasets because they are familiar with them. Trial and error, wastage, rework, and repetitive dataset searching are all risks in the process, which frequently forces workers to use “close enough” data while time is running out.

With the use of a data catalog, an analyst may swiftly search for data, view all datasets that are accessible, assess them all, decide which datasets to utilize based on their merits, and prepare and analyze data quickly and confidently.

It is typical to switch from spending 80% of the time gathering data and just 20% on analysis to 20% data preparation and 80% analysis. Without adding more analysts, organizational analysis capacity has increased and analysis quality has significantly improved.


It can be difficult to manage data in the era of big data, data lakes, and self-service. Data catalogs assist overcoming those obstacles. Active collection of data is a key component of a successful data catalog and a vital procedure for contemporary data management.
