Application generation for the simple database browser based on the ER diagram
نویسنده
چکیده
This paper describes a development technique for the rough browser of a database. The offered data browser or data management system can be generated automatically from the a physical data model represented by an ER diagram. The ER diagram used to generate a target application source text is described by common simple concepts and by some additional attributes with default changeable values. All the ER diagram elements are mapped to standard screen object groups and are the main components in the target system screens. Various screen templates for generated applications are defined depending on the entities, the relationships between them and an acceptable user interface. The generated application can be used for database browsing, data manipulating, system prototyping, fast developing of simple information systems and data analyzing.

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 کاملSchema Evolution through the Speci cation and Maintenance of Changes on Entities and Relationships ?
A exible database system needs to support changes to its schema in order to facilitate the requirements of new applications and to support interoperability within a multidatabase system. In this paper, we present an approach to schema evolution through changes to the EntityRelationship (ER) schema of a database. We enhance the graphical constructs used in ER diagrams, and develop EVER, an EVolu...
