How to Generate Reports › Function Point Calculation Report › Files/Entity Types

Files/Entity Types

The report counts entity types as files in each business system in which data is maintained. This includes Create, Update, Delete, Transfer, Disassociate and Associate actions.

The entity types maintained in the business system will be counted as files and those entity types which are read-only will be counted as interfaces.

In calculating the number of files, the report counts:

• Number of attributes in each entity type and all subtypes
• The number of relationships in which the entity type participates divided by 2, to avoid counting relationships twice.

The sum of the resulting numbers equals the Number of Data Elements for Function Point calculation in the following table. The Number of Record Types equals the number of subtypes of the entity type plus one for the parent entity type.

The table shows the number of Function Points for a file/entity type.
