Claim 14:
15. A remote database system being a part of a federated server comprising:
at least one processor; and
a memory storing an application program, which, when executed on the at least one processor, performs an operation comprising:
compile a query received from a client computing system to generate a query statement and a query access plan, wherein the query access plan incorporates a modified database access API that supports data serialization;
execute the query access plan to transmit the query statement to a remote database system of the federated system by calling the modified database access API to send the query statement and a data type mapping to a remote database system, wherein the data type mapping includes at least one data conversion definition for adapting respective remote database system data type formats to corresponding respective federation server system data type formats;
fetch from the remote database system a query result set including serialized BLOB data compatible with the federation server system; and
deserialize the serialized BLOB data and populate an in-memory data structure with deserialized query results
create and distribute a serialization library to be used by different components of the federated server system.
