ACCESSING NON-RELATIONAL DATA STORES USING STRUCTURED QUERY LANGUAGE QUERIES

摘要

The present invention provides a method and system for accessing non-relational data stores (108) using a structured query language queries. In an embodiment, an information server (106) generates a query based on user inputs received from a client device (102). The information server (106) determines an optimal query plan for the query and generates data store interface layer (DSIL) calls using the optimal query plan. Furthermore, the information server (106) generates Application Programming Interface (API) calls specific to one or more non-relational data stores (108) based on the corresponding DSIL calls. Consequently, the information server (106) obtains result sets from the one or more non-relational data stores 108 using the associated API calls and aggregates the result sets to generate a response to the query. Moreover, the information server (106) provides the response to the query to the client device (102).
