What is a DB catalog?
A database catalogue is a server feature that allows users and administrators to look up information on all databases installed on the server. A database catalogue stores metadata on each database, such as how many tables and rows are used in that database, in addition to common information. Going through the catalogue, which preserves all recent database changes as well as information on the people who made the changes, is one approach for administrators to check database modifications. Users usually don't have access to the catalogue, or only have limited access; the catalogue includes an email link that users can use to email administrators and seek access.
If a company or website has a server, it is common for the server to include many databases. These databases could store various sorts of data or be utilized to increase each database's storage capacity. Administrators may find it difficult to use or regulate each database, but the database catalog can assist them. This is due to the catalog's ability to store a file containing all of the databases, ensuring that administrators do not overlook any of them.
A database catalogue may access each database's metadata in addition to the name of each database on the server. This metadata contains basic database information like how many tables are currently being filled with data and how many users have access to the database. While the information cannot be modified, it does make it easier for users and administrators to quickly determine the size of a database.
