A request for at least a portion of a business object is received by a database from a client in a first half of a roundtrip between the client and the database. Each of the tables includes a primary key column and a plurality of records. The primary key column provides, for each record in the table, a primary key for one of a plurality of business objects. Thereafter, the database identifies records within a set of tables among a larger number of tables in the database by matching a primary key associated with the business object with the primary key in the primary key column. Once this identification has been made, the database obtains all values responsive to the request from the identified record and transmits, in a second half of the roundtrip between the client and the database, the obtained values for the business object to the client. |
