Answer / sikander

In programming, classification of a particular type of
information. It is easy for humans to distinguish between
different types of data. We can usually tell at a glance
whether a number is a percentage, a time, or an amount of
money. We do this through special symbols -- %, :, and $ --
that indicate the data's type. Similarly, a computer uses
special internal codes to keep track of the different types
of data it processes.
Most programming languages require the programmer to
declare the data type of every data object, and most
database systems require the user to specify the type of
each data field. The available data types vary from one
programming language to another, and from one database
application to another, but the following usually exist in
one form or another:

In a Cobol-DB2 program, I am fetching rows from 4 tables using cursor and then based on the a field present in that table, It processes the information accordingly..for example stat-c is one digit field..if stat-c is 'D' then the a row is deleted from table and written those details in to a file. If the stat-c is 'U' then a row is updated (hardcoded what to update)in a table and written those details in to a file. If the stat-c is 'I' then a row is inserted in a table and written those details in to two files. The issue is i have to include the intermediate commits. When an abend occurs, due to commit statement db2 tables will be saved, But there will be lose of file contents. When we resubmitting the job associated with this program there will be insert ,update and delete anomolies to avoid that what measures could be taken?. The intermediate commit is nothing but issuing commit after massive inserts, updates and deletes(sum of 500actions)
