Making data available from a database is disclosed. Making data available includes specifying a query function having a query function name, wherein the query function includes a structure and a member, determining the structure and the member included in the query function, wherein the query function has a query function name and includes the structure and the member, creating an index for the structure on the member, and compiling the query function to be available to a user by invoking the query function name without the user having to specify the structure and the member. Retrieving data from a database is disclosed. Retrieving includes invoking a query function that specifies a plurality of structures and a value, accessing a cross index of the plurality of structures, and using the cross index to access the data.
