Editor's note

The database management system is the heart of modern applications, and choosing the best DBMS software for your organization is imperative to the success of your IT projects and systems. Although the database landscape can be complex and confusing, this buyer's guide has simplified the process to help you sort through the different types of database management system (DBMS) software to determine which technology or technologies will best fit your organization.

And, in some cases, IT departments will want to consider combining multiple database technologies for some processing needs.

We will also show you how other companies are using DBMS software, and identify some of the leading vendors and the products they offer.
