 the collection of metadata associated with the use of data considered in a specific context (business, solution, technological …), which is a use that does not depend on any form of implementation.
The second functionality provides the collection of metadata associated with the use of data in its implementation context (operational data storage system, digital application, transactional system, analytical system…).
As we have seen in the previous chapters, there are several definitions of what is now called a “Data Catalog”.
So for the rest of the document we have decided to write our own definition of the Data Catalog. We will use this definition for the rest of the document.
Companies are using it to:
• Make an inventory and organize the data available in their system,
• Centralize and index business terms and technical data
• Track data and enable them to control the data life cycle
• Link different levels of data modeling,
• Enable data search using business vocabulary.
It can also be used to operate management rules adapted to different categories of data.
Through the use of the Data Catalog, these functionalities enable companies to make the most of the value that data brings.
