Thanks a lot for this information.Instantly The term " Financial domain " became clear to me.
I have never thought that it may split into many services you mentioned.I was thinking each of them a separate entity.
Please clear that industries/companies can deal with any number of services or retricted to one service.I mean , as a BA do we have to focus only on one specific area at a time or it may be combination of many.Like requirement gathering , making a documentation, forecasting etc.
It will be a great help if you can post some relevant information on each of this financial services in a separate folder/area.
Thanks
