Gartner Glossary

Ie (information Engineering)

A methodology for developing an integrated information system based on the sharing of common data, with emphasis on decision support needs as well as transaction-processing (TP) requirements. It assumes logical data representations are relatively stable, as opposed to the frequently changing processes that use the data. Therefore, the logical data model, which reflects an organization’s rules and policies, should be the basis for systems development.
