Abstract
This invention relates to query management. A query management method includes receiving a database query, generating an abstract syntax tree representation of the database path query into a set of java objects, and processing the abstract syntax tree representation of the database path query. The method further includes determining a selector upon processing the abstract syntax tree representation of the database path query and deriving a SELECT clause from the selector clause, where the SELECT clause indicates a portion of an expression from an XMeta Query Language (XMQL) query. The method yet further includes appending a FROM clause to the expression for the XMQL query, appending a WHERE clause to the expression for the XMQL query, and executing the expression for the XMQL query including the appended FROM clause and also the appended WHERE clause to access objects in an object repository.
