AC-systems enterprise resource planning - system in comparison to object-orientation
2002 (English)Independent thesis Advanced level (degree of Master (One Year))Student thesis
Abstract [en]

The company AC-Systems has encountered some problems while demonstrating their Enterprise Resource Planning-system Even(t)AC to IT-professionals; they tend to initially have trouble understanding the system. The objective with this report is therefore to facilitate the understanding of Even(t)AC (Even events with administration and control) for IT-professionals. A description of Even(t)AC’s four concepts; item, object, person and event is presented. These four classes of concepts are defined and compared to object-oriented objects. Objects in Even(t)AC are similar to object-oriented objects. Items with connected objects are similar to object-oriented classes, while items without connected objects are similar to objects in an object-oriented approach, but without an associated class, this is not possible in object-orientation. Persons in Even(t)AC are also similar to object-orientated objects, but are represented without a connected class. Events in Even(t)AC are quite comprehensive. They are built of a condition, a decision-making, a trigger and an action. One result of this study is the comparison represented in a number of metamodels of Even(t)AC’s concepts using the Unified Modeling Language. Parts of these metamodels are merged together in one metamodel, representing the concepts and their relationships. The metamodel representing the concept event in the coding process is the base for a representation of the coding process. Two parts of the coding process are represented, the “normal closing order” and the “payment bank giro, postal giro, and balance”. The metamodel of Even(t)AC’s concepts facilitated the understanding of the systems fundamental, the concepts usage and their relationships to each other. The representation of the coding process helped to understand its construction and potential. It facilitated the understanding of how items’, objects’ and persons’ properties are used as evaluation conditions during decision-making in events. It also helped to understand what is being processed in the coding process. We hope the metamodel will facilitate the understanding of Even(t)AC for IT-professionals. That it will relieve difficulties understanding the system’s concepts and the systems construction. We also hope that the model will help IT-professionals to understand the coding process’ construction and potential.
