Define a database management system. What is an entity? Differentiate between records and attributes
What will be an ideal response?
A database management system (DBMS) is a software application with which you create, store, organize, and retrieve data from a single database or several databases. In the DBMS, the individual database is a collection of related attributes about entities.
An entity is something you collect data about, such as people or classes. We often think of entities as tables, where each row is a record and each column is an attribute. This is also referred to as a field. A record is a collection of related attributes about a single instance of an entity. Each record typically consists of many attributes, which are individual pieces of information.
