Q1➡|UML(Unified Modeling Language) Match each UML diagram in List-I with appropriate description in List-II CODE:
i ➥ (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)
ii ➥ (a)-(iv), (b)-(ii), (c)-(i), (d)-(iii)
iii ➥ (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
iv ➥(a)-(i), (b)-(iv), (c)-(ii), (d)-(iii)
Show Answer With Best Explanation
Answer: iii Explanation: Activity diagram: Used to show the flow of a business process, the steps of a use case or the logic of an object behavior
Class diagram: The purpose of class diagram is to model the static view of an application. Class diagrams are the only diagrams which can be directly mapped with object-oriented languages and thus widely used at the time of construction. Use case diagram: Describe how the external entities (people, devices) can interact with the system. Use case diagrams are used to gather the requirements of a system including internal and external influences.
State diagram: Used to describe the dynamic behavior of objects and could also be used to describe the entire system behavior. State-chart diagram describes the flow of control from one state to another state. States are defined as a condition in which an object exists and it changes when some event is triggered. The most important purpose of State-chart diagram is to model lifetime of an object from creation to termination.

Q6➡|UML(Unified Modeling Language) The sequence diagram given in Figure 1 for the Weather Information System takes place when an external system requests the summarized data from the weather station. The increasing order of lifeline for the objects in the system are:
i ➥ Sat comms → Weather station → Commslink → Weather data
ii ➥ Sat comms → Comms link → Weather station → Weather data
iii ➥ Weather data → Comms link → Weather station → Sat Comms
iv ➥ Weather data → Weather station → Comms link > Sat Comms
v ➥ from UGC side Question remains cancelled
Show Answer With Best Explanation
Answer: v marks awarded to all Explanation: A connection is established in order to send and receive data between sender and receiver. And a link is disconnect after completion of data transfer.
Given diagram, Sat Comms requests data to whether station, whether station requests data to Comms link and comm link requests data from whether data.
Comm link gets data first from whether data then the link between comm link and whether data is smallest. Similarly lifetime if connection between Sat comms and whether station is largest.
Hence the increasing order of lifeline for the objects in the system are Weather data → Comms link → Weather station → Sat Comms. Note: Most appropriate answer is option-C.

Q7➡|ERP Which of the following statements about ERP system is true ?
i ➥ Most ERP software implementations fully achieve seamless integration
ii ➥ ERP software packages are themselves combinations of separate applications for manufacturing, materials, resource planning, general ledger, human resources, procurement and order entry.
iii ➥ Integration of ERP systems can be achieved in only one way
iv ➥ An ERP package implemented uniformly throughout an enterprise is likely to contain very flexible connections to allow charges and software variations.
Show Answer With Best Explanation
Answer: ii Explanation: ERP stands for Enterprise Resource Planning and refers to software and systems used to plan and manage all the. ERP software packages are themselves combinations of separate applications for manufacturing, materials, resource planning, general ledger, human resources, procurement and order entry.
