Company organizers and architects can describe operations using HOPEX Information Architecture by modeling data used when implementing business processes and applications. To this end, HOPEX Information Architecture makes available a number of tools and notations.

Using logical data models, you can build corresponding physical models, that is, create database tables, with its columns, indexes and keys as well as the relational diagram drawings. See Synchronizing logical and physical models.

You can also inventory applications that use the modeled logical data. See "Use of Data by the Information System".
