The design model consists of the data design, architectural design, interface design, and component-level design.

Characteristics of a good software design:
– The design must implement all of the explicit requirements contained in the analysis model, and it must accommodate all of the implicit requirements desired by the customer.
– The design must be readable, understandable guide for the whose generate code and for those who test and subsequently support the software.
-The design should provide a complete picture of the software, addressing the data, functional and behavioral domains from an implementation.

Transform mapping is a set of design steps that allows a DFD with transform flow characteristics to be mapped into a predefined template for program structure.

Object-Oriented Design
1) Subsystem layer
2) Class and object layer
3) Message layer
4) Responsibilities layer

Object oriented programming languages used for software development are: Python, Ruby, Scala, Smalltalk, Eiffel, Emerald, JADE, Self, Ada 95, Pascal, etc.

Software restructuring modifies source code and/or data in an effort to make it amenable to future changes. Restructuring does not modify the overall program architecture. It tends to focus on the design detailed of individual modules and a local data structure defined within modules.

The Rapid Application Development(RAD) model was proposed by IBM in 1980s.

The main cost of producing software is the manpower employed and the cost of developing software is generally measured in terms of person-months of effort spent in development.

n(n-1)/2 is the formula to calculate the number of communication channels on a project where N=the number of team members or stakeholders on a project.

Spiral model was introduced by Boehm in 1980s.

frankly speaking,mala pn answer mahit nahiye:)

Metric is a quantitative measure of the degree to which a system, system component, or process possesses a given attribute.

An object can instantiate two classes is not true about the object oriented design of software.

Perfective maintenance: Modification of a software product after delivery to improve performance or maintainability.

Project metrics enable project manager to-
-Assess status of ongoing project.
-Track potential risks.
-Uncover problem are before they go critical.
-Adjust work flow or tasks.
-Evaluate the project team’s ability to control quality of software wrok products.

Types of Process Performance Metrics:
– Efficiency Indicators
– Effectiveness Indicators
– Capacity Indicators
– Productivity Indicators
– Quality Indicators
– Profitability Indicators
– Competitiveness Indicators
– Value Indicators

Product metrics describe the characteristics of the product such as size, complexity, design features, performance, and quality level.

In functional decomposition, the data flow diagram is partitioned according to the logical closeness of the actigram.

Functional Decomposition is the process of taking a complex process and breaking it down into its smaller and simpler parts.

The spiral model is based on continuous refinement of key products for requirements definition and analysis, system and software design, and implementation. At each iteration around the cycle, the products are extensions of an earlier product. This model uses many of the same phases as the waterfall model, in essentially the same order, separated by planning, risk assessment, and the building of prototypes and simulations.
