Object Oriented Database - 5341 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†¦show more content†¦In other words, the schema of an object is not in first-normal-form. Examples of attributes that can comprise a complex object include lists, bags, and embedded objects. Object identity Every instance in the database has a unique identifier (OID), which is a property of an object that distinguishes it from all other objects and remains for the lifetime of the object. In object-oriented systems, an object has an existence (identity) independent of its value. Encapsulation Object-oriented models enforce encapsulation and information hiding. This means, the state of objects can be manipulated and read only by invoking operations that are specified within the type definition and made visible through the public clause. In an object-oriented database system encapsulation is achieved if only the operations are visible to the programmer and both the data and the implementation are hidden. Class or type hierarchies Any subclass or subtype will inherit attributes and methods from its superclass or super type. Support for types or classes âž ¢ Type: in an object-oriented system, summarizes the common features of a set of objects with the same characteristics. In programming languages types can be used at compilation time to check the correctness of programs. âž ¢Show MoreRelatedThe 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 MoreObject Oriented Database5350 Words   |  22 Pagesprocess architecture design should consider which processes are responsible for which use-cases. 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 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.
