What are the phases stages of it?
Which phase requires maximum efforts? Also explain why domain analysis i. Under what situation activity diagram should not be used? Which diagrams are preferable under such situations? Also give practical situations, when to use the following diagram:a. Use-Case Diagram, b. Object Diagram, c. Design a large number of simple numbers of simple classes, rather than a small number of complex classes. Design methods. Critique what we have proposed. It possible go back and refine the classes.
Prototyping: It is important to construct a prototype of some of the key system components shortly after the products are selected. A prototype is a version of a software product developed in the early stages of the products life cycle for specific, experimental purposes. It enables to fully understand how easy or difficult it will be to implement some of the features of the system.
It gives users a chance to comment on the usability and usefulness of the user interface design, it can define use cases and it makes use Case modeling much easier.
Prototyping was used as a quick and dirty way to test the design, user interface and so forth, something to be thrown away when the industrial strength version was developed. The rapid application development RAD refines the prototype into the final product. Prototypes have been categorized in various ways. This has the advantages of being very quick to implement, providing a good overall feel of the system and allowing users to evaluate the interface on the basis of their normal, expected perception of the system.
Vertical Prototype: It is a subset of the system features with complete functionality.
The advantage of this method is that the few implemented functions can be tested in great depth. The prototypes are hybrid between horizontal and vertical, the major portions of the interface are established so the user can get the feel of the system and features having a high degree of risk are prototyped with much more functionality.
Analysis Prototype: It is an aid for exploring the problem domain. This class of prototype is used to inform the user and demonstrate the proof of a concept. It is not used as the basis of development and is discarded when it has served its purpose.
Domain Prototype: It is an aid for the incremental development of the ultimate software solution.
It demonstrates the feasibility of the implementation and eventually will evolve into a deliverable product. The typical time required to produce a prototype is anywhere from a few days to several weeks, depending on the type and function of prototype.
The prototype makes the end users and management members to ascertain that the general structure of the prototype meets the requirements established for the overall design.
The purpose of this review is To demonstrate that the prototype has been developed according to the specification and that the final specification is appropriate. To collect information about errors or other problems in the system, such as user interface problems that need to be addressed in the intermediate prototype stage www. Prototyping is a useful exercise of almost any stage of the development.
Prototyping should be done in parallel with the preparation of the functional specification. It also results in modification to the specification.
Implementation: Software components are built and tested in-house, using a wide range of technologies. Computer aided software engineering CASE tools allow their users to rapidly develop information systems. The main goal of CASE technology is the automation of the entire information systems development life cycle process using a set of integrated software tools, such as modeling, methodology and automatic code generation. The code generated by CASE tools is only the skeleton of an application and a lot needs to be filled in by programming by hand.
Component-Based Development is an industrialized approach to the software development process. Application development to assembly of prebuilt, pretested, reusable software components that operate with each other: The two basic ideas of using Component-Based development.
The application development can be improved significantly if applications can be assembled quickly from prefabricated software components.
An increasingly large collection of interpretable software components could be made available to developers in both general and specified catalogs. A CBD developer can assemble components to construct a complete software system. The software components are the functional units of a program, building blocks offering a collection of reusable services. The object-Oriented concept addresses analysis, design and programming, where as component-Based development is concerned with the implementation and system integration aspects of software development.
Rapid Application Development RAD : RAD is a set of tools and techniques that can be used to build application footer than typically possible with traditional methods.
RAD encourages the incremental development approach of grow, do not build software. Testing: Refer Software Engineering Book www. Characteristics of Design Patterns: 1. It solves the problem Design patterns are not just abstract representations of theoretical research. To be accepted as a pattern it should have some proves practical experiences.
In the object-oriented paradigm this is accomplished by defining methods that invoke services on objects. Methods can be either public or private, i. This reduces a source of many common errors in computer programming.

The distinction between analysis and design is often described as "what vs. In analysis developers work with users and domain experts to define what the system is supposed to do. Implementation details are supposed to be mostly or totally depending on the particular method ignored at this phase. The goal of the analysis phase is to create a functional model of the system regardless of constraints such as appropriate technology. In object-oriented analysis this is typically done via use cases and abstract definitions of the most important objects.
The subsequent design phase refines the analysis model and makes the needed technology and other implementation choices. In object-oriented design the emphasis is on describing the various objects, their data, behavior, and interactions.
The design model should have all the details required so that programmers can implement the design in code. Object-oriented analysis[ edit ] The purpose of any analysis activity in the software life-cycle is to create a model of the system's functional requirements that is independent of implementation constraints.
The main difference between object-oriented analysis and other forms of analysis is that by the object-oriented approach we organize requirements around objects, which integrate both behaviors processes and states data modeled after real world objects that the system interacts with. In other or traditional analysis methodologies, the two aspects: processes and data are considered separately.
For example, data may be modeled by ER diagrams , and behaviors by flow charts or structure charts.
Common models used in OOA are use cases and object models. Use cases describe scenarios for standard domain functions that the system must accomplish.I've read the whole thing and have written a small program. Verification- Am I building the product right?
The object diagram contains classes interconnected by association lines. Application development to assembly of prebuilt, pretested, reusable software components that operate with each other: The two basic ideas of using Component-Based development. The specific problem is: remove duplications, shorten the waterfall descriptions, and make the statements more concise Please help improve this section if you can.
Participants Singleton class defines a Class function which can be accessed by the clients for creating instance. Non Generative patterns cannot be used in all the situation. All architecture is design but not all design is architecture. Easy to remember and context related names makes remembering patterns easy.
