This model was devel­oped to overcome the problems of complexity and inflexibility of the earlier two models in handling databases with many-to-many rela­tionships between entities. This model has been used by the ADABAS database management system of Software AG since 1970, and it is still supported today. The evolution of data models has gone on since the 1960s. In Enterprise Architect, a Logical data model is typically represented using the UML Class notation. These kinds of models are usually just a tiny bit better in terms of their fit to the data, but they can take a lot longer to optimise because you are optimising additional parameters (a lot of them in the case of protein datasets). The paper is written at a level suitable for a broad audience, and emphasizes how modeling has grown in scope to encompass not only structures imposed on data, but the operations on the data that form an important part of many environments in which databases are used. Application-oriented DBMS (spatial, scientific, engineering, etc.) Data Modeling and Data Models • Data modeling: Iterative and progressive process of creating a specific data model for a determined problem domain Data models: Simple representations of complex real-world data structures Useful for supporting a specific problem domain Model - Abstraction of a real-world object or event 4 The Evolution of Data Models Fourth Generation Object- Oriented (OO) Model Third Generation Relational Model It represented as objects that contain both data and operations.
