1. A system comprising two modules, which perform automation procedures of the data store arrangement and queries treatment in a data store system; wherein said automation procedures are based on creation and continuous updating of a hierarchical set of HRBlobs and said two modules are: a. an Analytical Dynamic Mechanism (ADM) module, which comprises components adapted to be able to decide how to act on each query, to collect the statistics from both said complementary system and said existing system, to manage the configuration of said complementary system, to update said hierarchical set of HRBlobs, and to process instructions from the supervisor; said components of said ADM comprising: a Query Analyzer; a Statistics Collector; and a Decision Maker; and optionally comprises one or both of the following components: a Queries Cache; and a Query Router; b. a Data Arrangements Module (DAM), which comprises components adapted to be able to handle the data in the Data Store of said existing data store system and said HRBlob set, to load data from said Data Store into said complementary system, to perform the configuration and the updates of said HRBlobs according to instructions received from the ADM, to extract the relevant HRBlob to provide the response to said query, and to provide query execution statistics; said components of said DAM comprising: a Control Module; a Query Handler; a HRBlobs Storage component; a HRBlobs Handler component; a HRBlobs Arrangement Engine component; a Base Data Loader component; and an Execution Statistics Provider component.
