8、he retail sector. </p><p>　　Current status</p><p>　　Four or five years ago DBMS was just like a data store, with medium and large companies only looking at it as a tool for storing data. Then ar

9、ound three years ago it really moved into what is called the relational database space. This is where the concept of applications on databases came into the picture.</p><p>　　In terms of users there has been

10、 a shift from meagre database administrators to developers to data warehouse managers and also towards business intelligence usage that involves a whole lot of people and not just CIOs. This means users have also evolved

11、 with the evolution of the product, its usage and market. Till the time it was a data store, database administrators could have managed it. But when it became a data warehouse, CIOs and skilled technical experts got invo

12、lved.</p><p>　　That is why DBMS is now an integral and crucial part of the overall IT policy of large enterprises. The importance of DBMS has come to fore especially after the adoption of ERP and CRM solutio

13、ns. If you look at the top of the pyramid, for the top few IT spenders, DBMS has become as important as network infrastructure. “As a matter of fact, that is why it is also driving the platform strategy of vendors,” says

14、 Malik. However, the trend is still evolving in the SME space. </p><p>　　One can now see a very strong momentum in the marketplace. As data continues to grow exponentially, one witnesses the type of informat

15、ion changing from record-oriented to content-oriented data. Databases have become content or information repositories. Handling that and supporting applications is not only transaction-oriented but analysis-oriented. Mix

16、ed content is going to be a way in which databases differentiate themselves. There is the trend to push more analytics into the database, with abi</p><p>　　XML will be important as users now store and build

17、content repositories to represent that kind of content. In terms of topology of database performance, the ability to get performance, scalability and high availability in different environments is also gaining importance

18、. </p><p>　　Another clear trend in the database space is towards building infrastructure that is robust, secure and low-cost. That is why almost all vendors are looking at offering unlimited scalability and

19、reliability on low-cost computers.</p><p><b>　　Drivers</b></p><p>　　Apart from the increasing adoption of databases in different verticals, the return on investment (RoI) and functio

20、nality of databases are also fuelling the growth of DBMS in the country. Consumers, especially after the dot-com debacle, have started looking at spending less and deriving more RoI from new technology, products and soft

21、ware. Any vendor who relates his offering to RoI would be a successful vendor.</p><p>　　Open Source</p><p>　　No one has so far dumped a clustered Oracle 9i database and replaced it with a free,

22、open source database downloaded from the Web and running on a bunch of Intel-based Linux/free OS servers. But a growing number of users are pioneering these freely available databases. These users say that open source da

23、tabases are reaching a stage where they can become the latest addition to their inventory of open source tools, including the Linux operating system, the Apache Web server and the Tomcat Java ser</p><p>　　Ac

24、cording to these users, the main attractions of an open source database are:</p><p>　　?Very fast performance, especially in read-only applications. </p><p>　　?No or nominal licensing costs. &l

25、t;/p><p>　　?Low administrative and operational costs. </p><p>　　As to the back-end servers, users are still ingrained with Oracle or DB2, which has a fair amount of support for Linux. </p>

26、<p>　　It is a typical pattern in companies that are experimenting with open source databases. High-volume database updates, which are the essence of transaction-processing applications, remain anchored on products s

27、uch as Oracle’s 9i and IBM’s DB2 Universal Database, and increasingly Microsoft’s SQL Server. But there are a host of new application areas that don’t require the complex and equally expensive features of conventional da

28、tabases. </p><p>　　MySQL open source database from MySQL has spread from being used by a few groups to the core infrastructure of the Internet portal. MySQL is a core piece of the content-generation system f

30、rs typically have the freedom to change any part of the source code and use it without charg</p><p>　　An alternative arrangement is the Berkeley Software Development licence which is used by PostgreSQL.org.

31、Developers can use, copy, modify, and distribute this software free of cost. </p><p>　　There is an array of open source databases. Firebird, based on Borland’s venerable Inter Base database is one of the few

32、 that have the support and blessings of vendors and the well-organised community of coders. </p><p>　　MySQL is also proving to be popular among open source communities. Every time a new programming language

33、comes out, the first thing that developers usually do is add database connectivity to MySQL. PostgreSQL is the most matured of the open databases, and PostgreSQL.org maintains an extensive Web presence for its developer

34、community. It is a Canadian company that offers applications along with support services. Red Hat bases its product offerings on PostgreSQL. </p><p>　　The open databases are often storehouses of innovation.

35、MySQL has an architecture that has a core relational manager that can be used by different kinds of plug-in data handlers. These open databases tend to be far simpler than their conventional counterparts in all these are

36、as. They also have low operational overheads. </p><p>　　A common criticism of open source databases is that they don’t support transactions or don’t do as well as commercial products. For example, MySQL has

37、a fast database for content store, but it is still immature in terms of transaction processing at the back-end. However, immaturity in some areas of an open database might not be a problem if the software has what you ne

38、ed in other areas, or has a credible track record of delivering new features on a regular basis. </p><p>　　Conclusion</p><p>　　The database segment will continue to grow as businesses rely more

39、and more on information as a source of competitive advantage. However, the market has definitely evolved over the years though it has not yet reached high maturity levels. As the SME segment has started adopting the tech

40、nology, experts opine that there is going to be huge momentum in the market. The Indian SME market is no longer just a PC market; rather, it has become a well-networked and well-connected segment, which is why it </p&
