Combine different datasets easily and efficiently

Query builder With a database you can combine different data easily. No more error-prone cut-and-paste to force the data into a different format. Do away with all the intermediate Excel spreadsheets that are often generated when manipulating data. (And which you often daren't delete just in case they contain important information.)

Data manipulation is performed using Queries. These use Structured Query Language, SQL, to combine, update and manage data, but often the user need not know any SQL to perform complex tasks. In Microsoft Access, for example, the visual Query Builder provides an intuitive interface that makes most queries simple.
