The market is growing bigger in terms of size, and will continue to gain prominence in 2020. With the consolidation, standardisation and centralisation of IT systems underway in most organisations, the demand for highly scalable and reliable database systems is on the rise. According to reliable industry estimates, the Indian database market is currently at about $100 million, and the top three players put together have a market share of more than 70 percent. IDC expects the information and data management software segment to grow at a pounded annual growth rate (CAGR) of 17 percent till 2020. “There will be independent solutions like business intelligence that are largely going to drive the use and adoption of databases,” says Tarun Malik, product marketing manager, Microsoft India. The importance of having a database and data warehouses for various specific applications will also be a factor of growth to drive the market. Early adapters of sophisticated database management and business intelligence tools would be large puting verticals like the government, the banking, financial services and insurance (BFSI) sector, tele, IT services, manufacturing and the retail sector. Current status Four or five years ago DBMS was just like a data store, with medium and large panies only looking at it as a tool for storing data. Then around 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. In terms of users there has been 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 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 involved. That is why DBMS is now an integral and crucial part of the overall IT policy of large enterprises. The importance of DBMS has e to fore especially after the adoption of ERP and CRM solutions. If you look at the top of the pyramid, for the top few IT spenders, DBMS has bee as important as work infrastructure. “As a matter of fact, that is why it is also driving the platform strategy of vendors,” says Malik. However, the trend is still evolving in the SME space. One can now see a very strong momentum in the marketplace. As data continues to grow exponentially, one witnesses the type of information changing from recordoriented to contentoriented data. Databases have bee content or information repositories. Handling that and supporting applications is not only transactionoriented but analysisorie
