Abstract: A method, computer program product and system for converting Structured Query Language (SQL) statements into the Open Database Connectivity (ODBC) standard. The source code of a database application may be parsed to identify one or more keywords. These keywords may be used to identify SQL statements as well as variables that are used to process the SQL statements. Upon identifying the SQL statements, the SQL statements may be evaluated. The SQL statements evaluated may then be matched with particular functions in a function library, i.e., a collection of functions stored in data files. These functions may implement particular ODBC calls thereby enabling SQL statements to be converted into the ODBC standard. A function call, i.e., a call to that function, may be substituted for the corresponding SQL statement. The function call may then be implemented resulting in the execution of the ODBC calls.

Abstract: The method and system of the present invention provides improved access to databases in a computer system. The present invention includes a plurality of data sources, the data sources including at least one non-relational data source; a server coupled to the plurality of data sources, the server capable of providing client access to the plurality of data sources; and a store place data access layer (SPDAL) coupled to the server and the at least one non-relational data source, the SPDAL providing relational features to the at least one non-relational data source. In the preferred embodiment, the relational features provided include a two-phase commit process; a process for performing Structured Query Language (SQL) operations from within a single application; a referential integrity process; and a process for providing indices for non-relational data source files.

Abstract: Methods, systems and computer program products are provided which allow for accessing at least one data source by intercepting a command to a standard relational database management system and determining if the intercepted command accesses the data source utilizing a logical table name. If the intercepted command accesses the data source utilizing the logical table name, then the logical table name is translated to a physical table name. The intercepted command is the provided to the relational database management system utilizing the physical table name translated from the logical table name so as to provide access the data source utilizing the logical table name. Furthermore, if the intercepted command accesses the data source utilizing a logical table name and a logical column name, then the logical table name is translated to the physical table name and the logical column name translated to a physical column name.

Abstract: A system and method for allowing a user to characterize an application are disclosed. In one aspect, the method and system allow a user to characterize a database engine. The database engine utilizes a particular interface for communicating with an application. The method and system include determining a query spectrum including plurality of queries corresponding to a plurality of query types. The plurality of query types are chosen such that any possible query can be classified as being of one query type. The plurality of queries is compatible with the particular interface. The method and system include running the query spectrum on the database engine and determining a time taken to run each of the plurality of queries on the database engine. In another aspect, the method and system are for characterizing the application. In this aspect, the method and system include characterizing the database engine using a query spectrum including a first plurality of queries compatible with the particular interface.
