A database catalog is a feature in a server that allows administrators to control information about each database, including metadata and recent changes. Users have limited access and can request access via email.
A database catalog is a feature included in a server that allows users and administrators to control information about each database installed on that server. In addition to common information, a database catalog also contains metadata about each database, such as how many tables and rows are used in a particular database. One way for administrators to audit database changes is to browse the catalog, because this saves any recent changes to the database along with information about who made the changes. Users typically have no access, or limited access, to the catalog; the catalog automatically has an email link so users can email admins and request access.
If a business or website owner has a server, usually several databases are included on that server. These databases can contain different types of information or can be used to maximize the storage threshold of each database. It can be difficult for administrators to operate or regulate each database, but the database catalog can help them with this task. This is because the catalog saves a file of all databases, so administrators won’t forget about any of them.
In addition to the name of each database on the server, a database catalog can also access each database’s metadata. This metadata contains basic information about the database, such as the number of tables currently populated with data and the number of users who have access to the database. While the metadata can’t be changed, it’s easier for users and administrators to know how large a database is at a glance.
The database catalog doesn’t just store metadata; it also stores information about recent changes. This section of the catalog displays all changes and displays the user’s name and Internet Protocol (IP) address so administrators know who is responsible for changes. If the change damages the database, administrators will know who is at fault.
While administrators typically have unlimited access to the database catalog, most users have limited or no access. This is because users typically do not need metadata information, nor do they normally need to know the number of databases on a server. If users need to log in, the catalog automatically has an email link that allows users to send emails to administrators to request access. Administrators may or may not grant this access, based on users’ reasons and history.
