Part of a technical system, isolated at the logical level, so that it reflects an aspect
Introduction to the notion
By applying architecture rules, the information system is decomposed into three strata:
- A core, called the “Foundation” stratum and made up of logical constituents that have been derived from the semantic aspect.
- An intermediary level isolating the organizational choices, called the “Activation” stratum.
- A periphery that provides the entry points into the system, with a variety of workstations or other interfaces (potentially towards other systems), called the “Interaction” stratum.
Related terms: stratification, logical aspect, logical architecture, Enterprise System Topology.
