Answer Explanation for Question: The overall description of a database is called
A database schema defines all the constraints that need to be applied to the data, as well as how the data will be organized and arranged. It is a skeleton framework that represents the logical view of a database. Database schemas describe the entities in the database and the relationships between them. The schema offers a description of the database, which can be portrayed by schema diagrams. Schema is designed by database designers so that programmers can understand and make use of the database.
In choosing a database, one of the things you need to consider are the shape of your data, the model you will use, and how the relationships we create will help us develop a database schema. The database schema describes how our data will look. It does not store data directly, but instead describes how the data will be arranged and how other tables or models will be related. Each entry in our database will be an instance of the database schema. The schema describes all properties in the document. A database schema’s complexity and size depend on the scope of your project. The visual style of a database schema allows developers to organize the database and its relationships before writing code.
In relational database management systems (RDBMS), a DBMS is a software system that stores and retrieves user data using a scheme that adheres to the ACID principles. DBMS design and management responsibilities usually fall to the Database Administrator (DBA). DBAs are responsible for ensuring that data analysts and database users can access information easily.
