##DHP-Aggregation

|
This module defines a set of oozie workflows for the **collection** and **transformation** of metadata records.
|
|
|
|
Both workflows interact with the Metadata Store Manager (MdSM) to handle the logical transactions required to ensure
|
|
the consistency of the read/write operations on the data as the MdSM in fact keeps track of the logical-physical mapping
|
|
of each MDStore.
|
|
|
|
It defines [mappings](mappings.md) for transformation of different datasource (See mapping section). |
