Current trends

In 1998, database management was in need of new style databases to solve current database management problems. Researchers realized that the old trends of database management were becoming too complex and there was a need for automated configuration and management[5]. Surajit Chaudhuri, Gerhard Weikum and Michael Stonebraker, were the pioneers that dramatically affected the thought of database management systems [5]. They believed that database management needed a more modular approach and that there are so many specifications needs for various users [5]. Since this new development process of database management we currently have endless possibilities. Database management is no longer limited to “monolithic entities” [5]. Many solutions have developed to satisfy individual needs of users. Development of numerous database options has created flexible solutions in database management.

Today there are several ways database management has affected the technology world as we know it. Organizations demand for directory services has become an extreme necessity as organizations grow. Businesses are now able to use directory services that provided prompt searches for their company information [5]. Mobile devices are not only able to store contact information of users but have grown to bigger capabilities. Mobile technology is able to cache large information that is used for computers and is able to display it on smaller devices [5]. Web searches have even been affected with database management. Search engine queries are able to locate data within the World Wide Web [5]. Retailers have also benefited from the developments with data warehousing. These companies are able to record customer transactions made within their business [5]. Online transactions have become tremendously popular with the e-business world. Consumers and businesses are able to make payments securely on company websites. None of these current developments would have been possible without the evolution of database management. Even with all the progress and current trends of database management, there will always be a need for new development as specifications and needs grow.

As the speeds of consumer internet connectivity increase, and as data availability and computing become more ubiquitous, database are seeing migration to web services. Web based languages such as XML and PHP are being used to process databases over web based services. These languages allow databases to live in "the cloud." As with many other products, such as Google's GMail, Microsoft's Office 2010, and Carbonite's online backup services, many services are beginning to move to web based services due to increasing internet reliability, data storage efficiency, and the lack of a need for dedicated IT staff to manage the hardware. Faculty at Rochester Institute of Technology published a paper regarding the use of databases in the cloud and state that their school plans to add cloud based database computing to their curriculum to "keep [their] information technology (IT) curriculum at the forefront of technology.[6]

Advanced DBMS: (i.e)D DBMS: Distributed Data Base Management System:A distributed database is a collection of data which belong logically to the same system but are spread over the sites of the computer network.The two aspects of a distributed database are :
