41 CHAPTER 2 ■ The New Information Management Paradigm Query Developing map-reduce jobs to execute your queries is not a trivial task and certainly not as simplistic as writing SQL. To overcome this challenge, SMAQ systems incorporate a higher-level query layer to simplify both the specification of the map-reduce operations and the retrieval of the result. Query layers typically offer features that handle not only the specification of the computation but also the loading and saving of data and the orchestration of the processing on the map-reduce cluster.
