Access Data Stores supports
A Data store can be supported by different object types:

A file structure represents a file folder or a single file used in the technical architecture of an application. • A NOSQL data domain
NoSQL data domain represents a set of data stored in a NOSQL database management system and used in the technical architecture of an application. • A Relational Schema
Relational schema represents a set schema stored in a database management system and used in the technical architecture of an application. Accessing to data areas with HOPEX IT Architecture
