To address the issue of latency in relational database systems, a computerized database management system comprising a database server, a processor, and associated random access memory is provided. The processor may configure an in-memory database in the random access memory to have tables, each containing a plurality of cells associated memory addresses, establish a direct table association between an origin cell and a target cell within the tables, receive a request to perform a join database operation of a first table including the origin cell on a second table including the target cell, dereference the direct table association for the origin cell to obtain a value of the target cell stored at the memory address for the target cell, execute the join database operation to produce a joined table including the value, and store the joined table at a new location in the random access memory.
