Database Management

Relational Database Management Systems (RDBMSs) continue to do the heavy lifting in data management, while newer database management systems are taking on prominent roles as well. NoSQL database systems such as Key-Value, Column Family, Graph, and Document databases, are gaining acceptance due to their ability to handle unstructured and semi-structured data. MultiValue, sometimes called the fifth NoSQL database, is also a well-established database management technology which continues to evolve to address new enterprise requirements.

The optimizer is the heart and soul of a relational DBMS. It analyzes SQL statements and determines the most efficient access plan for satisfying each statement. The optimizer accomplishes this by parsing the SQL statement to determine which tables and columns must be accessed. It then queries system information and statistics stored in the system catalog and directory to determine the best method of accomplishing the tasks necessary to satisfy the request.

Now, they are commonplace, while databases in the hundreds of terabytes inhabit the part of the map that says "there be dragons." While VLDBs are quite common on SQL Server today, highly scalable systems that can be flexibly extended in the same fashion as Oracle/RAC are less so.
