Uniface was developed on the principles of the American National Standards Institute, (ANSI), 3-schema architecture. First proposed in 1975, this was a standard approach to the building of database management systems consisting of 3 schema (or metamodels): Conceptual schema—definition of all the data items and relationships between them.
The CIM Schema is a conceptual schema which defines the specific set of objects and relationships between them that represent a common base for the managed elements in an IT environment. The CIM Schema covers most of today's elements in an IT environment, for example computer systems, operating systems, networks, middleware, services and storage.
For this, the service provider publishes the structure of the data that it expects within the incoming message from the service consumer. In case of services being implemented as web services, [4] this would be the XML schema document. Once the service consumer knows the required data model, it can structure the data accordingly.
Architect Perspective (System Logic) – The architect's plans are the translation of the drawings into detail requirements representations from the designer's perspective. They correspond to the system model designed by a systems analyst who must determine the data elements, logical process flows, and functions that represent business entities ...
The Enterprise Continuum is a way of classifying solutions and architectures on a continuum that range from generic foundation architectures through to tailored organization-specific both within and outside the Architecture Repository. [19] These include architectural models, architectural patterns, architecture descriptions, and other artifacts.
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]
The service-orientation design principles help in distinguishing a service-oriented solution [14] from a traditional object-oriented solution by promoting distinct design characteristics. The presence of these characteristics in a service-oriented solution greatly improves the chances of realizing the aforementioned goals and benefits.
The notion of a three-schema model was first introduced in 1975 by the ANSI/X3/SPARC three level architecture, which determined three levels to model data. [1]The three-schema approach, or three-schema concept, in software engineering is an approach to building information systems and systems information management that originated in the 1970s.
