  Abstract:  

This paper proposes some solutions and discusses some issues related to the mapping of relational data and queries to a Key-Value store.The problem is stated for Location-based services (LBS), which deal with millions of users and thus millions of database records. The mapping process of a relational table consists in a transformation that assigns a part of the tables`s row to the Key part and another part to the Value. We discuss two approaches to the mapping: generic and a LBS specic.The generic approach is a universal solution that can be applied to any relational to Key-Value mapping process.

Key words and phrases. Key-Value store, relational model, data design, query mapping.
