Intro  Counting  Data FPs  Transactional FPs  Estimation 
If all data is stored in a database, each table will be an ILF or EIF, with a corresponding number of function points.
Data functions are counted before transactional functions because they clarify issues. If you are storing your input in a database, tables will either be an ILF (a table the application writes/updates) or an EIF (a table the application only reads). If a table is used only to join to tables for a manytomany relationship, don't count it unless it contains additional information about the relationship. These must be groups of logically related, user identifiable, data.
The complexity (low, average, or high) of each ILF or EIF is computed from DETs and RETs.


The number of function points is computed by a matrix based on the numbers of ILFs, EIFs and their complexities.
Determine whether each table is an ILF or EIF, and compute its complexity (low, average, high). Fill in the Counting form to get the number of data function points.
