Old-style database systems solve old-style problems; we need new-style databases to solve new-style problems. While the need for conventional database management systems isn't going away, many of today’s problems require a configurable database system. Even without a crystal ball, it seems clear that tomorrow’s systems will also require a significant degree of reconfigurability. As programmers and engineers, we learn to select the right tool to do a job; selecting a database is no exception. We need to operate in a mode where we recognize that there are options in data management, and we should select the right tool to get the job done as efficiently, robustly, and simply as possible.
