What is the database catalog?
The database catalog is a function included on a server that allows users and administrators to check information about each database installed on this server. Along with common information, the database catalog also contains metadata in each database, for example how many tables and rows are used in a specific database. One way to control database changes is to go through the catalog because it will save all recent changes in the database along with information about the people who have made these changes. Users usually do not have access or have limited access to the catalog; The catalog automatically has an e -mail link so users can make the administrators and ask for access. These databases can have different types of information or can be used to maximize the storage threshold of each database. It may be difficult for administrators to use or regulate the database, but the database catalog can help them with this task. This is because the catalog stores a file of all databases, so administrationThey will not forget any of them.
In addition to the name of each database on the server, the metadats of each database can also access the database catalog. This metadata contains basic database information, for example how many tables are currently filled with data and number of users who have access to the database. Although metadata cannot be changed, it makes it easier for users and administrators to know how large the database is in a quick view.
The database catalog not only stores metadata; It also stores information about recent changes. This part of the catalog shows all changes and displays the name and IP address (IP) of the user so that the administrators know who is responsible for the changes. Lizmune is a damaging database, then administrators will know who is to blame.
While administrators usually have unlimited access to the database catalog, most users have limited or no access. This is because users usually nepoMethad information may not even know about the number of databases on the server. If users need access, the catalog has an e -mail link that allows users to require administrators access to administrators. Administrators may or may not grant this approach based on reasons and user history.
