... Introduction to LOGOB
LOGOB is a deductive database model and is similar to DATALOG. LOGOB predicates represent objects without methods. ... LOGOB has been designed and implemented in C. There are user interfaces, two centralized database management systems and a distributed database management system in LOGOB [1].
LOGOB integrates Object-oriented and deductive database models. ...
In the LOGOB database model, the results of queries are objects and methods are not associated with objects as known ‘declarativeness’. LOGOB supports rules and objects which are stated in a hierarchy. ... Moreover, LOGOB is embedded in an Object Oriented Language and a distributed DBMS for LOGOB is the best implementation in these models. ... LOGOB Data Model
Data model in LOGOB consists of objects and object types. ... Referential Integrity is included in LOGOB. ... 2 Object Reachability Graph
LOGOB Database model includes rule definitions. ...
In the next section, Storage Implementation and management of LOGOB Database model is described in the project. ... LOGOB Storage Implementation
In Logop, all the information is stored in the object and rule forms. ... 1 Object Type Storage
Object types are stored in the form of records. ... Storage format for a property definition in turn is shown in the following figure:
Figure 3. ... Conclusion
LOGOB is a deductive database model, whose predicates represent objects without methods. In this view, LOGOB is similar to DATALOG. LOGOB is implemented in C /C++ Object Oriented Programming language. ... Object and rules store all the information in LOGOB. ... In this project, we deal with the implementing of the LOGOB storage management. We create an object and its properties according the LOGOB data model. The operations in the implementation are to create objects, list objects and its’ properties, search and delete the object by name. ... “The Design and Implementation of a DBMS for LOGOB, A Deductive DataModel with Object Predicates”, 1995
