Briefly describe the relational database model.
What will be an ideal response?
The relational database model describes data using a standard tabular format; all data elements are placed in two-dimensional tables called relations, which are the logical equivalent of files. The tables in relational databases organize data in rows and columns, simplifying data access and manipulation. In the relational model, each row of a table represents a data entity or record. Each column represents an attribute or field. After entering data into a relational database, users can make inquiries and analyze data through use of the selecting, projecting, and joining functions. Selecting involves removing rows according to certain criteria. Projecting involves eliminating columns in a table. Joining involves combining two or more tables.
