Somebody could tell me what is the connection or difference between these 3 technologies. Appreciate all your inputs.
<i>difference between these 3 technologies.</i>
MDM--> Master Data Management. It is key enabler of consistent master data within a heterogeneous system landscape. It ensures cross-system data consistency through streamlined data import, consolidation, and distribution mechanisms.
Data WareHousing--> It is BW concept that talks about storing of historical data, data that is not frequently used but required sometimes for operational use. it maintains master data as well as transactional data. Data warehousing has own ways of preserving this data. for example master data is stored in infocubes etc.
XI--> It is integration technology and platform for SAP and non- SAP applications,cross component business process management. Take an example where sender system is sending and IDOC and receiver system demands this information in file format.. so here comes role of XI to manage mapping and configuration between these 2 systems
<i>connection between these technologies</i>
Imagine a scenario wherein R/3 is sending IDOC which contains master data that needs to be updated on MDM repository.. then in this case R/3 will send IDOC to XI , Xi will convert it to XML file, and this XML file will be picked by import manager of MDM and hence the data is saved to repository for further use and thereby ensuring consistancy if remote systems are using this data
Hope this satisfies your curiosity.
