- A database system aims to achieve a highly organized collection of data along with appropriate tools and applications that facilitate processing and access to that data.
- Early databases were relatively "flat," which means they were limited to simple rows and columns, like a spreadsheet.
- Today's relational databases allow users to access, update, and search information based on the relationship of data stored in different tables. Relational databases can also run queries that involve multiple databases.
Database Key Features :
1. Data consistency
2. Simple data access
3. Integrity constraint
