Simon thus notes that. 4. "Hierarchic systems are usually composed of only a few different kinds of subsystems in various combinations and arrangements " . The Unified Modelling Language, or the UML, is a graphical modelling language that provides us with a syntax for describing the major elements (called artifacts.

Draw the Interaction diagram for an ATM — used for card based banking system. Prepare object diagram showing at least 10 relationships among the following object classes. Include associations and qualified associations, aggregations, generalizations, and multiplicity.
You may add additional objects.
Also show attributes and operations. 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. Its a proven concept Patterns must have a successful history. It describes a relationship Patterns do not specify a single class instead it specifies more than one classes and their relationship. It has a human component - Good patterns make the job of the programmer easy and time saving.
Contents of Design Pattern: Name of the pattern is used to identify the pattern as well as an descriptive of the problem solution in general. Easy to remember and context related names makes remembering patterns easy.
Context of the pattern describes when and where the pattern is applicable. It also describes the purpose of pattern and also the place where it is not applicable due to some specific conditions. Solution of the design pattern is describes how to build the appropriate design using this appropriate design.
Consequences of design patterns describe the impact of choosing a particular design pattern in a system. Where are they used. The Singleton Design Pattern: 1. Pattern Name Singleton 2.
Intent To ensure a class has only one instance a global point of access to it. Motivation Its common in software development where some component developers specify that more than one object of a Class alive make systems ambiguous. Participants Singleton class defines a Class function which can be accessed by the clients for creating instance.
Collaborations Clients access a singleton object solely through instance operation. Non Generative patterns cannot be used in all the situation. In general framework is a generic solution to a problem that can be applied to all levels of development. Design and Software frameworks and most popular where Design pattern helps on Design phase and software frameworks help in Component Based Development phase.
Framework groups a set of classes which are either concrete or abstract. This group can be sub classed in to a particular application and recomposing the necessary items. Frameworks can be inserted in to a code where a design pattern cannot be inserted. To include a design pattern the implementation of the design pattern is used.
Design patterns are instructive information; hence they are less in space where Frameworks are large in size because they contain many design patterns. Frameworks are more particular about the application domain where design patterns are less specified about the application domain.
The Purpose-Driven Life: What on Earth Am I Here For?
Note: Include the details of Microsoft. Net development framework. Object oriented methods suddenly had become very popular and it was apparent that the techniques to help people execute good analysis and design were just as important as the object-oriented methodologies, sometimes called second-generation object-oriented methods.
Many methodologies are available to choose from for system development. The methodology is based on modeling the business problem and implementing the differences lie primary in the documentation of information, modeling notations and languages. An application an be implemented in many ways to meet some requirements and provide the same functionality.The access layer AL , which is a key part of every n-tier system, is mainly consist of a simple set of code that does basic interactions with the database or any other storage device.
And, finally, how do users use the system use case? A good pattern will do the following: The first 3 are transient data, data that cease to exist beyond the lifetime of the creating process.
Because software has become much more complex in recent years, developers are finding it more challenging to build complex applications within short time periods.
