Object Oriented Database - 5350 Words

Introduction â€Å"Choosing the right OODB architecture can mean orders of magnitude difference in performance and scalability characteristics rather than a few percentage points as found in relational implementations.† To achieve maximum performance and scalability the most important thing is choosing the right application architecture. OODBs give applications much more direct access to the persistent data, so application architecture has much more impact on performance than is the case with an RDB. Or to put it another way, when using an OODB the application architect has much more power to optimize performance than when using an RDB. Consequently the application architecture has more effect on performance and scalability than the choice of†¦show more content†¦Thus, a database system contains the five following features: Persistence As in a conventional database, data must remain after the process that created it has terminated. For this purpose data has to be stored permanently on secondary storage. Secondary Storage Management Traditional databases employ techniques, which manage secondary storage in order to improve the performance of the system. These are usually invisible to the user of the system. Concurrency The system should provide a concurrency mechanism, which is similar to the concurrency mechanisms in conventional databases. Recovery The system should provide a recovery mechanism similar to recovery mechanisms in conventional databases. Ad hoc query facility The database should provide a high-level, efficient, application independent query facility. This needs not necessarily be a query language but could instead, be some type of graphical interface. The above criteria are perhaps the most complete attempt so far to define the features of an object-oriented database in 1989. Further attempts to define an OODBS standard were made variables of researchers. One of them is a group called Object Data Management Group (ODMG). They have worked on an OODBS standard for the industry. The recent release is ODMG-2 in1997.

Partitioning of the dataset should aim to identify which objects are accessed by which of these processes. Transactional analysis should analyse the transactional requirements of each use-case, and the objects that are accessed in each transaction. Object interaction diagrams are useful in this respect. The OO design phase should include the design of optimal access and index structures to support the navigationRead MoreThe Object Oriented Database Model1990 Words   |  8 Pages History of Object Oriented Databases Miral Patel IST 7000: Data Management Wilmington University Frank Richey Date: 11-27-2016 Introduction The Object oriented databases models have been around since the seventies when the concept of object oriented programming was first explored.

The interest for the development of such systems stems from the need to cover the modeling deficiencies of their predecessors, that is the relational database management systems. They were intended to be used by applications that have to handle big and complexRead MoreBenefits Of Using Object Oriented Database1352 Words   |  6 Pagestable record in the database as it has many to many relationships. It is flexible so it is easier to navigate and search for information. ImageDisadvantages If you are a first time user it can be difficult to use. Difficulties can occur when adding information because this can change the whole database. Object oriented database Object databases store objects instead of data like integers or strings. Objects are made up of attributes and methods which is how the object behaves and the functionsRead More Relational and Object-oriented Database Management Systems Essay2156 Words   |  9 PagesRelational and Object-oriented Database Management Systems A database is a â€Å"shared collection of logically related data designed to meet the information needs of multiple users in an organization† (Hoffer 709). Databases contain data records or files, such as sales transactions, product catalogs and inventories, and customer profiles. Databases allows multiple users in an organization to easily access, manage, store, and update data when needed.

Secondly while the relational data base stores data as tables, the object model stores data as objects and creates associations. This can create a multiple set of attributes for each object such that the data base is moreRead MoreDatabase And Knowledge Base Management System1364 Words   |  6 Pages Trident University Rondia Riles Module 1 Case Assignment ITM 540: Database and Knowledge-Base Management Dr. Ying Liu August 16, 2013 Introduction Information and data have become the cornerstone of business enterprises today.
