What is coupling?

refers to the level of interdependency or interrelationship among the modules in a system.

What is Request for Proposal (RFP)?

- A binding offer to accomplish described in it. - A document that solicits a formal proposal from a potential vendor, developer, or service provider.

False

Contracts document the message passing that takes place between objects.

What is convention?

A class has an attribute in which a range of values has a semantic meaning. This class has __________ consistence.

What is cohesion?

A class/object should only represent one thing, and a method should only solve a simple task. This principle is often referred to as?

False

A precondition is a constraint that must always be true for all instances of a class. T/F?

What is storage efficiency and speed of access?

A relational database may be optimize for _______?

False

A walkthrough is a custom-built add-on program that interfaces with the packaged application to handle special needs. T/F

True

Abstraction and refinement are two processes closely related to factoring T/F?

What is an alternative matrix?

Can be used to organize the pros can cons of the design alternatives so that the best solution will be chosen in the end.

True

Concept maps are used to discover the structural and behavioral models

What does the Human-Computer interaction layer do?

Contains classes associated with the View and Controller idea from Smalltalk. Keeps the specific user-interface implementation separate from the problem domain classes.

False

Custom development allows developers to speed up the way they solve business problems. T/F?

What are files and databases?

Data may be stored in ____________?

False

Dynamic binding refers to the ability of object-oriented systems to have data types before run time. T/F

False

Enterprise resource planning (ERP) Applications are small single function software packages that are inexpensive and easy to install and have only minor problems and fast, easily recognizable benefits. T/F

True

Functional method is the best type of method cohesion T/F?

What does the problem domain layer do?

Further detail the classes so we can implement them in an effective manner.

3

How many different types of constraints are typically captured in object-oriented design

What is first normal form.

If the data does not have any repeating fields it is in __________

What is third normal form.

If the logical data model contains fields that depend on another nonprimary key field, then it is in violation of the rules of

In terms of abstraction, what is the lowest level?

True

In the design phase we address the functional and nonfunctional requirements T/F

What is customization?

Manipulating certain parameters to refine the way features work in a software package.

True

Object wrappers enable object oriented systems to interact with legacy systems through an Application Program Interface (API). T/F

What is method, class and generalization/specialization?

Object-oriented systems have three general types of cohesion:

True

Partitions are based on the pattern of activity among the objects in an object-oriented system. T/F?

What is Object-Relational database management system.

Relational database which support user-defined data types is an example of what database management system?

False

The only issue associate with implementing problem-domain is?

True

The physical architecture layer will include the classes that interact with middleware applications T/F?

What is system integration?

The process of building new systems by combining packaged software, existing legacy systems, and new software written to integrate everything together.

What is factoring?

The process of separating out a module into a stand-alone module.

What are interaction and inheritance?

The two types of coupling in object oriented systems.

What does the foundation layer do?

This layer contains the classes that represent the fundamental data types.

What is many?

Transaction-processing systems are designed to accept ________ transactions

What is an object wrapper?

an object that "wraps around" a legacy system, enabling an object-oriented system to send messages to the legacy system.

What is connascence?

generalizes the ideas of cohesion and coupling, and it combines them with the arguments for encapsulation.
