Stepwise Re-Engineering and Development of Object-Oriented Database Schemata
نویسندگان
چکیده
We present a general approach for re-engineering of object-oriented database schemata. The approach consists of four dependent steps: (1) description of the data within the underlying basic data format, (2) application of a powerful semantic data model in order to construct a semantic database schema, (3) translation of the achieved schema into a general object model, and (4) implementation of the object schema in a concrete object-oriented database system. As an instantiation of this general procedure we report on a case study carried out in an industrial context where an Extended Entity-Relationship model was used as the semantic data model and ObjectStore as the implementation

The Reengineering of Relational Databases Based on Key and Data Correlations
This paper addresses the problem of recovering object-oriented schemata from relational databases. Solutions to this problem are particularly useful for designing wrappers for federated database systems. Our goal here is to describe a reverse engineering methodology for the DOK federated database system (Tari et al. 1996), enabling the wrappers to express relational schemata as object-oriented ...
متن کاملDeclarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey
One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...
متن کاملObjects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...
متن کاملOn Mapping Between UML and Entity-Relationship Model
Nowadays, the Entity-Relationship Model (ERM) is the most important and widely used method for modeling data and designing databases. On the other hand, the Uniied Modeling Language (UML) is expected to become more and more popular in object-oriented analysis and design (OOA/OOD). As a by-product of OOA/OOD, a database design can be derived by mapping of objects to entities. The purpose of this...
متن کاملFlexible Generation of Global Integrated Schemata using GIM
The integration of schemata is a very essential but also a very complex task in a federated database environment. Especially the integration of diierent inheritance hierarchies into one hierarchy is not satisfactorily solved up to now. We show, why some existing approaches fail and propose a new algorithm, which further meets the demand for complete, correct and minimal integrated schemata. Fur...
