22.   Simulation techniques have been developed to allow scientists and planners to build working models of the systems which they are studying.

23.   At the same time, both Iran and Iraq were developing new techniques.

24.   Data analysis techniques were largely developed to cater for the implementation of database systems, although that does not mean that they cannot be applied to non-database situations.
