A database is a software application program that runs on computers and helps end users to create, maintain, retrieve, modify data related to any business or other activity.
A database usually consists of relational data organized in terms of tables. Like student roll number, name , age, institute, address etc. A unique primary key (roll number) is used to create, index, retrieve, modify entries in the table.
Database management system is the controlling software that allows creation, maintenance, modification of databases.
