Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

Question

In the variable-length record format, a null bitmap is used whenever it is necessary to demonstrate that an attribute does not contain any data. Under certain peculiar circumstances, the vast majority of a tuple's attributes are represented by the value null. It is possible to cut the cost of a null attribute down to just one bit by modifying the method in which entries are stored in a database.
The performance of a database depends on how it processes blocks.
