NORMA supports ORM2 (second generation ORM), and can map object-role models to implementation targets, such as database engines, object-oriented code, and XML schema. Dr. Terry Halpin 's 2008 book, Information Modeling and Relational Databases: From Conceptual Analysis to Logical Design [ 3 ] "...explains the ORM2 notation, as supported by the ...
The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term " schema " refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases ).
which looks like this: The complete XSD schema for DGML is available at .DGML not only allows describing nodes and links in a graph, but also annotating those nodes and links with any user defined property and/or category.

"Examples of artifacts include model files, source files, scripts, and binary executable files, a table in a database system, a development deliverable, a word-processing document, or a mail message." [1] Artifacts are the physical entities that are deployed on Nodes [1] (i.e. Devices and Execution Environments). Other UML elements such as ...
A conceptual schema or conceptual data model is a high-level description of informational needs underlying the design of a database. [1] [2] It typically includes only the core concepts and the main relationships among them. This is a high-level model with insufficient detail to build a complete, functional database. [3]
Physical data model options. [1] A physical data model (or database design) is a representation of a data design as implemented, or intended to be implemented, in a database management system. In the lifecycle of a project it typically derives from a logical data model, though it may be reverse-engineered from a given database implementation.
Database design is the organization of data according to a database model. The designer determines what data must be stored and how the data elements interrelate. With this information, they can begin to fit the data to the database model. [1] A database management system manages the data accordingly.
