Claim 6:
7. A database server, comprising a processor, a memory, and a computer program that is stored in the memory and executable by the processor, wherein when the processor executes the program the processer is configured to:
receive a fusion query submitted by a client, wherein the fusion query comprises a first type of query and a second type of query;
process, by using a main execution engine, the first type of query to obtain a first processing result;
determine, based on metadata, a first extensible execution engine configured to process the second type of query, and an interface corresponding to the first extensible execution engine wherein the metadata comprises information about an extensible execution engine supported by a multi-model database management system, and the information about the extensible execution comprises a type of the extensible executing engine and an address of a server on which one or more instances of the extensible execution engine are located;
pass, by using the interface, the second type of query to the first extensible execution engine;
process, by using the first extensible execution engine, the second type of query to obtain a second processing result; and
generate a query result based on the first processing result and the second processing result, and returning the query result to the client.
