ICT2622 MOCK EXAM QUESTIONS 2021. Object-Oriented Analysis. In a workflow diagram, the arrows that cross the center line are used to identify what? Actor and use case relationships From this list, the developer will then create a use case diagram. A use case diagram is used to graphically portray the use cases and users involved in the subsystem. Figure 1-14 illustrates a simple use case diagram for the Supplier Information Subsystem showing the four use cases as ovals and the two users as stick figures. The lines connecting users and use cases shows who uses the system for the use case: The purchasing agent carries out all four use cases, but the manager also looks up suppliers or contacts. PG 19 Relationships between objects The arrows that cross the line between users (center) represent the interactions between the user and the system. These are critically important because they designate situations where the developers must provide a screen or Web page that either captures or displays information. PG 20 2. Clients play what role in the development of the new system? Fund the project The client is the person or group that provides the funding for the project. In many cases, the client is senior management. However, clients may also be a separate group, such as a corporation’s board of directors, executives in a parent company, or the board of regents of a university. PG 48 3. The technique used to identify use cases based on external, temporal, and state events is the _______. Event decomposition technique There are three types of events to consider when using the event decomposition technique to identify use cases: external events, temporal events, and state events (also called internal events). The analyst begins by trying to identify and list as many of these events as possible, refining the list while talking with System users. PG 76 4. A synonym for cardinality (used with UML class diagrams) is ____. Multiplicity Relationship relationship a term, in database management, that describes a naturally occurring association between specific things multiplicity in UML, a measure of the number of links in a particular association between a thing (object) and one or more other things (objects) cardinality a measure of the number of links in a particular relationship between a thing (database data entity) and one or more other things (database data entities) PG 99 5. In a sequence diagram the syntax of a message is given by the following: [A] B := C (D) The letter B represents what? Return value [true/false condition] sequence-number: return-value: = message-name (parameter-list) PG 402 This study source was downloaded by from CourseH on 11-08-2021 01:05:55 GMT -06:00 This study resource was shared via CourseH 6. A relational database table is in ____ normal form if every non-key field is functionally dependent on the primary key. Second first normal form (1NF) a restriction that all fields must be atomic, or single valued second normal form (2NF) a restriction that a table is in 1NF and that each non-key attribute is functionally dependent on the entire primary key third normal form (3NF) a restriction that a table is in 2NF and that no non-key attribute is functionally dependent on any other non-key attribute PG 275 7. The UP life cycle model includes all of the following: Phases, disciplines, and iterations UP life cycle: phases, iterations, and disciplines. It includes all the key UP life cycle features and is useful for understanding how a typical information system development project is managed. PG 310 8. Which diagram is directly used to identify methods and write programming code for objectoriented systems? Design class diagram An object-oriented system designer must provide enough detail so a programmer can write the initial class definitions, including the method code. PG 374 9. When denoting a specific object in a sequence diagram, a ____ serves as the divider between the object name and the specific object identifier. Colon 10. Those activities that enable a person to understand and specify what the new system should accomplish are usually referred to as system . Systems analysis PG 160 11. The Interface requirements requirements describe interactions between systems, e.g. the method of communication between one system and another system. PG 46 12. An event that occurs simply by reaching a point in time is called a temporal event event PG 77 13. A UML class that is allowed to have a set of actual objects within it is called a concrete class class. PG 109.
