For many years, businesses in various sectors have been using relational database systems to effectively represent their data and information. A typical relational database stores data in a collection of tables with rows and columns. As interest in the utilization of better database systems increased, many organizations have started to use a wide range of new applications in various fields including engineering design, telecommunications, and geographic systems. Moreover, organizations have been dealing with huge amounts of complex data and that’s why it’s extremely important to invest in applications that can handle this kind of data. It is difficult to represent complex data in an ordinary relational database because of the database’s restricted attributes. Object databases emerged to solve this problem and other problems associated with the relational database model and other database models. Object databases are known for their high performance and the ability to handle complex data effectively.

Top Object Databases : ObjectDatabase++, ObjectStore, GemStone/S, Perst, ZODB, Wakanda, ObjectDB, ODABA, Objectivity/DB are some of the Top Object Databases.

What are Object Databases?

An object database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. Object database combine database capabilities with object-oriented programming language capabilities. Object databases based on persistent programming acquired a niche in application areas such as engineering and spatial databases, telecommunications, and scientific areas such as high energy physics, molecular biology, embedded use in devices, packaged software, and real-time systems. Most object databases also offer some kind of query language, allowing objects to be found using a declarative programming approach.

An object database refers to a database system that represents data or information in the form of objects. The objects used to represent information are essentially the same objects used in object-oriented programming. Unlike relational databases, object databases do not use tables to represent information. They are basically a combination of the capabilities of object-oriented programming and databases. This means object databases use object-oriented languages and have the key features of a database system such as storage, querying, and transactions. The object-oriented concepts of a typical object database include complex objects, object identity, classes, class hierarchies, encapsulation, overriding, late binding, and overloading. One of the key objectives of an object database is to provide support for the persistence of objects in addition to supporting most of the features of a database system. That’s why object databases are often used to handle complex data in scientific fields, engineering, telecommunications, and real-time systems.

There are different types of object database products to suit the needs of your organization, company, or business. Each product has its own features, but almost all object databases have the following features.

Top Object Databases

  • Query Language – Most object databases use a query language. This language uses declarative programming techniques to find objects or retrieve data from the database.
  • Transparent Persistence – This is a very important feature of object databases. It refers to the database’s ability to use an object programming language to manipulate data.
  • ACID Transactions – Every effective database system can perform transactions. Object databases can perform ACID (Atomicity, Consistency, Isolation, Durability) transitions. This means all transactions are complete and there are no conflicting changes. Moreover, users can abort transactions in case of an error.
  • Database Caching – Object database systems have a caching mechanism that creates a partial replica of the database. Caching is a data retention method that makes it possible to minimize disk access or network traffic flow. It allows applications to access objects from program memory instead of disks.
  • Recovery – Object databases include a feature that allows users to recover information in case of a system or application failure.

Some of the benefits include:

  • Object databases handle complex data.
  • Transparent persistence means higher performance.
  • Object databases are reliable because they support ACID transactions.
  • Less code and more efficient coding.
  • Quick data access.

ODABA

The theoretical base for ODABA is Unified Database Theory, which defines abstract database model levels for different types of databases. ODABA combines the flexibility of key/value stores (P0) with the simplicity of relational databases (P1), the complexity of object-oriented databases (P2) and analytical features of data warehouse technologies (P3). Relational databases (entity-relationship models) are considered to be P1 database models, which store data in well-structured instances that are collected in tables. P1requirements are also fulfilled by object-oriented databases, which may store data in well-structured object instances collected in extents. This way, ODABA also supports P1requirements. Besides an instance schema, P2…

Bottom Line

ODABA is an object-oriented database management system (OODBMS) on a high conceptual level.
