Information Engineering Methodology
An information engineering methodology has many advantages. The methodology is based on data modeling and the concept of a data model. The data model defines the Entity types, attributes and relationships between the entities. The Information Engineering Facility is a computer-aided software engineering toolkit developed by Texas Instruments. The software engineering toolset provides one model implementation, consistency checking, management tools for application developers, and a fourth-generation programming language with numeric functions, security within the data model, and inherent database management facilities.
Data model
Data models are representations of data in a given domain. They assume underlying structures and are expressed using a dedicated grammar. A data model represents classes of entities, attributes of information, and relationships between entities. It is a representation of the organization of data and is used in information engineering methodology. There are several different types of data models. In this article, we’ll discuss three of them. …
