19. Define Business layer
Business layer is responsible for supporting business process life cycle. Business
process lifecycle consists of five stages: design, model, simulate, monitor, manage, and
optimize business processes. Business layer users are either business analysts, or business
managers. Business analysts create the initial drafts of the business processes, and business IT6801 Question Bank Service Oriented Architecture
managers will manage and monitor those business processes.

20. Define Business services layer
Business services layer holds orchestration and choreography engines under
governance mechanisms to map business processes to composing Web services.
Orchestration and choreography engines are the mapping enablers of business processes into
executable services. Web services are stateless services that can not maintain business logic,
operation flow, or user state; so, the need of an orchestration layer to include business logic is IT6801 Question Bank Service Oriented Architecture
addressed. Orchestration and choreography engines maintain business process workflow
logic, performance requirements, and system/user state. Business services layer has access to
business rules repository.

21. Define Orchestration service
Orchestration services encapsulate the entire business process. For example, a service
containing the entire flow of the Employer Registration” business process is an orchestration
service. The complete registration process identifying the employer type, determining
liability and registering the employer in the database and various other steps. IT6801 Question Bank Service Oriented Architecture

16. List out OLAP operations in multidimensional data model. (May/June 2009)
 Roll-up – performs aggregation on a data cube
 Drill-down – is the reverse operation of roll-up.
 Slice and dice – Slice operation selects one particular dimension from a IT6702 Question Bank Data Warehousing and Data Mining
given cube and provides a new sub-cube. Dice selects two or more
dimensions from a given cube and provides a new sub-cube.
 Pivot (or) rotate – The pivot operation is also known as rotation. It rotates
the data axes in view in order to provide an alternative presentation of data.
17. Mention the functions of OLAP servers in the data warehousing architecture.
(Nov/Dec 2010)
The OLAP server performs multidimensional queries of data and stores the
results in its multidimensional storage. It speeds the analysis of fact tables into IT6702 Question Bank Data Warehousing and Data Mining
cubes, stores the cubes until needed, and then quickly returns the data to clients.
