Abstract
A system and apparatus is disclosed which stores, retrieves and analyzes relational and non-relational data. An application program provides a data query statement containing both relational and non-relational portions to a relational server. In an embodiment, the query statement is a Structured Query Language ('SQL') CONTAINS stored procedure or CONTAINS function statement. The relational data server then provides the non-relational query to either a text queue or database management language ('DML') queue. A non-relational data server then accesses either the text queue or the DML queue. The non-relational data server obtains pointers to the non-relational data and stores them in a temporary table. The pointers and relational data portion are processed by the relational server to obtain the relational and non-relational data. In an embodiment, the non-relational data server is a text server including an engine, filter, lexer, data storage and word list.
