QaoS serves as gateway within GAP to the QaoS databases of Algebraic Objects in Berlin. The database frontend is able to output internal data in a GAP-conform format. This GAP package both triggers the database and retrieves the data. Beyond that, it is also able to retransform received information into GAP objects which then could be used in the `normal way'.

QaoS itself is a backend/frontend combination of an SQL database which is designed to grant public anonymous access via HTTP for reading operations, and restricted access via HTTP and TCP/IP for writing operations.

The package functionality is partly driven by external utilities. At the moment we support cURL only. cURL is used for network communication, HTTP GET and POST requests and reading results from the network socket, while the GAP part is used for content dependent operations.

Data for Transitive Groups has been taken from the current GAP distribution. We like to thank Alexander Hulpke for his permission to offer transitive group data in our databases.
