Database

A collection of integrated and related files

DB table (or file)

A collection of related records

Record

A collection of related fields

Field

A group of characters

Character

Basic building block of information, represented by a byte


Example of relationships among rows

The hierarchy of data with examples

The Hierarchy of Data, with Examples

DB tables


The traditional approach

The Traditional Approach

Separate files are created and stored for each application program.


The database approach

The Database Approach

A pool of related data is shared by multiple application programs. Rather than having separate data files, each application uses a collection of data that is either joined or related in the database.


The database approach1

The Database Approach

Foundational Concepts

  • Database – Highly organized information (Tables, Indexes)

  • DBMS – Database Management Systems (Database, Interface, Tools)

    Use a DBMS software to create, store, organize, and retrieve data from a single database or several databases

    Example: Microsoft Access
