| Summary: | ObjectStore is an object oriented database management system. It provides a tightly integrated language interface to the traditional database management system features such as persistent distributed data access and associative queries. ObjectStore enables "ordinary" C and C++ programmers to add persistent database to their applications without having to learn a new language and without sacrificing any performance. This is an advantage over the relational database approach in which there is an impedance mismatch between database query language and the high level programming languages. ObjectStore and C++ programming language share the same data model, for instance base types, such as integers, characters, and pointers, as well as more complex types, such as structures and classes. The operators defined on the data types are also equivalent. Actions such-as pointer dereferencing (- >) are valid for both persistent and transient data, with no difference to the programmer. ObjectStore also ensures that the resulting unified interface yields access speed for persistent objects that are usually equal to that of in-memory dereferences of transient data. Our objective in this report is to describe how to create database applications, using the fundamental features of ObjectStore such as, Database access, Transactions Exceptions, Collections, Queries, Indexes and Relationship facilities. The general information and instructions for generating schemas, compiling, linking and debugging ObjectStore are explained in details. We develop an application, Airline Reservation to examine most of the database functions in ObjectStore system. This application has written in C++ language and uses ObjectStore API whenever needed to use database |
