• Components in a single table database. 11 GEN

Background

• A database is a compilation of information that is organized so that it can be easily accessed
• A table is a structured collection of related data within a database
• A single table database is a database that consists of only one table

Single Table Database (Example)

• An example of a single table database is a simple counter. The counter writes its count to a database that contains one table, Table. As the counter increments, the field Counter_Column is updated with the new value, and resets to 0 when reset. The simple database consists of a field value, in the column Counter_Column, in the table Table.

Components of a Single Table Database

• A table stores mass amounts of information in tabular form
• A field (or column) show vertically in a table
  • Each column has a column name
  • This column name also presents the field name in a table
  • The column value makes up the field's value
• A record (or row) holds the particular grouped information for an item in a table
• A key field is a compulsory unique identifying field given to each record
  • It often consists of a unique numeral, such as a Student ID number
