Data Processing On Internet and Object Oriented Database Systems

  • Data Processing On Internet
The Internet was introduced in 1969 by Advanced Research Projects Agency (ARPA) of USA. Today, most the database systems are online. It means that databases, DBMS software and database application are stored on the Web server. The database technology is used in conjunctions with Internet technology to access data on the Web server. The database application are developed using Internet technology to access the database on the Web server. The database on the Internet uses the hypertext transfer protocol (HTTP), dynamic, hypertext markup language (DHTML), and extensible markup language (XML), to communicate information between database application and database stored on the Web server.
  • Object Oriented Database Systems
In the middle of 1980s, it had become clear that there were several fields where relational databases were not applicable, due to the types of data involved. These included medicine, multimedia and high-energy physics, all of which needed more flexibility in how their data was represented and accessed. This let to research being started in object-oriented databases where users could define their own methods of access to data and how it was represented and manipulated. In the start of 1990s, two systems had appeared: the Object-Oriented DBMS (OODMBS) and the object-relational database management system (ORDBMS). However, unlike previous models, the actual composition of these models are not clear. This evolution represents third generation database management system.
