SUBJECT CODE & NAME	BT8901, Object Oriented Systems
BK ID	B1185
CREDITS	4
MARKS	60

Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

Question. 1. Explain State charts and Activity Diagrams with examples.

Answer:A program with a graphical user interface is a good example of an event-driven system, as the program must react to user input events. The timing and type of these events is unpredictable. A server is another good example because the timing and types of client requests can be unpredictable.

Statechart Machines

Harel introduces the concept of a statechart machine as an abstract model of a reactive system. A statechart machine is an example of a finite-

Question. 2. What is Booch methodology? Explain its macro and micro development processes.

Answer:Booch system development process is a widely used object oriented process, covers the analysis and design phases of an object – oriented system.

The Booch method consists of the following diagrams:

Question. 3. Explain the structural things in UML.

Answer:To understand the UML, you need to form a conceptual model of the language, and this requires learning three major elements: the UML's basic building blocks, the rules that dictate how those building blocks may be put together, and some common mechanisms that apply throughout the UML. Once you have grasped these ideas, you will be able to read UML models and create some basic ones. As you gain more experience in applying the UML, you can build on this conceptual model, using more advanced features of the language

Question. 4. Discuss about Extracting Entity Classes. Draw necessary diagram.

Answer:An entity relationship diagram (ERD) is a representation of data within a domain. It consists of entities as well as relationships between entities.

An entity can be a tangible, physical object such as a school or student, or a concept such as a reply or a transaction. Entity can be identified by extracting objects that are relevant and meaningful to the problem domain and the system to develop. In entity relationship modeling, the term entity has synonyms "table", "database table", "entity-type

Question. 5. Explain the Elaboration Phase and Construction Phase of unified process.

Answer:The life of a software system can be represented as a series of cycles. A cycle ends with the release of a version of the system to customers.  Within the Unified Process, each cycle contains four phases. A phase is simply the span of time between two major milestones, points at which managers make important decisions about whether to proceed with development and, if so, what's required concerning project scope, budget, and schedule.

Question. 6. Explain Synchronize-and-Stabilize Team Organization with an example.

Answer:Synchronize-and-stabilize is a software life cycle development model. It allows the teams to work efficiently in parallel on different individual application modules. This is done while frequently synchronizing the work as individual’s and as members of parallel teams and periodically stabilizing and/or debugging the code through out the
