5. Setting up a database table Records REf'l'l) T\'PE ADDRESS! 4 This detached bungalow comprises one reception room, two bedrooms, bathroom, hall, kitchen, garage space and a small walled garden. It is situated in a small village outside a busy market town and is within easy driving distance of shops. There is a regular bus service past the door. Central heating is by electric night store heaters. 2 Using Paradox When using the Paradox database management program you will find that from the start all database files are referred to as tables, and they always are displayed as such.

These are records 4 and 7. ,. 1 2 3 4 5 b 7 B 9. 19, and select the Edit option from this. Highlight the first record to be deleted and press the Delete key. The record disappears. 20 shows the screen after the deletion and when the next record to be deleted is highlighted.

Do not, however, think that tape methods are dead and gone. Magnetic tape provides an easy and cheap way of archiving data. Since many database tables are transient and change from day to day, it is good practice to make backup copies of the data they contain on, very often, a daily basis.
