Few other terminologies of RET and DET are to be understood here as well to determine the function points. A RET (record element type) is a user recognizable subgroup of data elements with as ILF or EIF A DET (data element type) is a unique user recognizable, non-repeated field either maintained in an ILF or retrieved from an ILF or ELF. Identify the transaction functionalities (EI, EO, EQ) All the tree Transactional functionalities are "elementary processes" An Elementary Process is the smallest unit of activity that is meaningful to the user(s). The elementary process must be self-contained and leave the business of the application in a consistent state. An EI (External Input) is an elementary process of the application which processes data that from of the application. enters outside the boundary Maintains one or more ILF. An EO (External Output) is an elementary process that generates data that exits the boundary of the application (i.e. presents information to the user) through processing logic, retrieval of data through ILF or EIF. The processing logic contains mathematical calculations, derived data etc. An EQ (External Query) is an elementary process that results in retrieval of data that is the (i.e. present information to the sent outside application boundary user) through retrieval of data from ILF or EIF. The processing logic should not contain any mathematical formula, derived data etc. Using the above data we can calculate the UFP (Unadjusted Function Points) all the basic data & transactional functionalities of the system have been defined we can use the following set of tables below to calculate the total UFP. Now for each type of Functionality determine the UFP's based on the below table. For EI's, EO's & EQ's determine the FTR's and DET's and on that determine the Complexity and hence the Number of UFP's it contributes. We have to calculate this for all the EI's, EO's & EQ's.
