Structured query language server data sources often times have different language constructs for interacting with software data consuming clients. A unified structured query language data server is interposed in the network chain between the structured query language server data sources and the networked data consuming software clients to present an interface to retrieve networked data from different SQL database server types in one single structured query language to software consumers in the form of computer programs accessing the data on a network. These data consuming clients can now access any number of SQL database sources with one single set of structured query language commands through the invention which acts as a query language translating device, though not exclusively. The invention also provides a unified authentication method to access data in structured query language server data sources connected to it. Data consuming software clients can also use the invention to collate several requests from same or different types of structured query language data servers into one single structured data response based on a set of requests using one structured query language based on the ISO/ANSI SQL standard.
