make detailed errors as they write application code, but they are less likely to make deep errors that are difficult to resolve.
Master files They are used for the storage of permanent , or semi-permanent , data, which is used in applications such as stock, sales or payroll. Some of the fields tend to contain data which is fairly static, for example, customer name and address, whilst data in some fields is continually changing, for example, customer balance, as transactions are applied to the file. Such updating is carried out, either through the direct entry (on line) of individual transactions, or from an accumulated set of entries stored on a transaction file. Transaction File These are transient and only exist to allow the updating of master files. Each transaction record contains the key field value of the master record it’s to update (to allow correct matching with its relevant master record), together with data gathered from source documents, for example, invoice amounts which update the balance field in customer accounts
- transaction file is sorted into the same order as the master file
- each transaction record is read and used to update the corresponding record in the master file
- new master record is written to the new master file
- after the last transaction record is processed, remaining old master records are written to the new master file

Question 4 Question 5 5.1 Program documentation - describes the inputs, outputs, and processing logic for all program modules. The program documentation is a kind of documentation that gives a comprehensive procedural description of a program. It shows as to how software is written. Program documentation even has the capability to sustain any later maintenance or development of the program. The program documentation describes what exactly a program does by mentioning about the requirements of the input data and the effect of performing a programming task. Thus, if you want to know what a program is meant to do and how it has to be executed, you should refer to the program documentation. The most common examples would be the instruction manuals for a software product, which is given to the end-user. Thus the instruction manual for a programming language like Java or for understanding a word processor can come under the purview of program documentation. The description languages used are informal and are intended to make life easy for the end-user. http://kninn.blogspot.co.za/2010/03/what-is-program- documentation.html E-R diagram for the registrar’s of_ PC Training.
