ESA = SOA + business context. So when we are talking about ESA adoption, it means SOA plus business process oriented view of technology. ESA, itself is not a technology layer. It is a business focused approach to a services-oriented enterprise architecture adoption. So while all the patterns of SOA apply, ESA will talk about how to align business and IT. It will talk about IT governance models, for that matter. It will talk about how organizations need to realign for transforming into an agile enterprise. The ESA composer (can be compared to ASAP roadmap content) has a lot of content for organizations on ESA adoption phases.

Master data are data which is used long term in the SAP system for several business processes and ensures NO redundancy of data in the system. Master data has an organizational aspect as the information is organized into VIEWS which are assigned to organizational elements. e.g.: Customer master = 3 views:
- (Client): General data
- (Company code): Financial Accounting data
- (Sales Area): Sales data
Document is a data record that is generated when a transaction
is carried out. Every transaction creates a document which contains all
relevant predefined information from the master data and
organizational elements assigned.
OLTP
OLTP(Online transaction Processing) database contains detailed transaction data. Such database may contain some derived data, which is calculated from the basic data elements, e.g. the primary element can be the item price while the derive data can be the item's average price over a period of time.
The data in OLTP database is structured and organised
so it favours speed, performance, reliability, data integrity and security.
