Field Names

Entering Field Names

0 I entered all of the Field Names that were specified in the Data Item list provided on the Edexcel website

Data Types

Name of Species0 I kept the Data Type for

“Name of Species” as Text, because then this allows an unique text, in either numbers or letters, or a mixture of both

0 I changed the field size to 50 as this is the maximum amount that will be entered into this field. I changed the other properties to make sure that there would be no duplicates (e.g. Indexed Yes (No duplicates).

0 This ensures that each piece of data entered into this field will be individual.

0 The primary key in this field also ensures that each entry is unique.

Group

0 I entered a Lookup Wizard so that the options specified in the Data Item sheet would come up as options when entering data into the database

0 I also changed the Field Size to 18, as this is the maximum characters in any of the options in the drop down list.

Importing Data

Take Two0 I removed
