Hadoop
Parallel DBMSs system which improves performance through parallelization of various operations, such as loading data, building indexes and evaluating queries. Vertica and Oracle 11g-r2 fall into the parallel DBMS trend.
Hadoop has been touted for big data analysis but it is well suited for small data analysis as well.
We help clients choose the best tools for their data analysis and data mining requirements. If your company is small and is expected to have less than 100 nodes traditional RDBMS with Parallel processing capabilities seem to be justified
If, however with large data of the order of 300-400 TB, MapReduce framework built on Hadoop gives best results both in terms of simplicity and cost effectiveness.
