5. USECASE DIAGRAMS

A use case diagram in the Unified Modeling Language (UML) is a type of behavioral diagram defined by and created from a Use-case analysis. Its purpose is to present a graphical overview of the functionality provided by a system in terms of actors, their goals (represented as use cases), and any dependencies between those use cases.
The main purpose of a use case diagram is to show what system functions are performed for which actor. Roles of the actors in the system can be depicted.
A use case is a set of scenarios that describing an interaction between a user and a system. A use case diagram displays the relationship among actors and use cases. The two main components of a use case diagram are use cases and actors.

An actor is represents a user or another system that will interact with the system you are modeling. A use case is an external view of the system that represents some action the user might perform in order to complete a task.
Use cases are used in almost every project. They are helpful in exposing requirements and planning the project. During the initial stage of a project most use cases should be defined, but as the project continues more might become visible.

6. DATA FLOW DIAGRAM

System design is concerned with how the system functionally is to be provided by the components of the system. System design process may involve the design of special purpose hardware as well as real time software design.
Design is the process of applying various techniques and principles for the purpose of defining a device, a process on a system in sufficient detail to permit its physical realization. It is a process through which requirements are translated into a representation of the software engineering process and is applied regardless of the development paradigm that is used. From a project management point of view software design is conducted in two steps. Preliminary design is concerned with the transformation of requirement to the architectural representation that lead to detail data structure and algorithm representations for software.
System design involves translating information requirements and conceptual design into technical specification and general flow of processing. After considering the requirements of the firm, needs are identified, related information is gathered to verify the problem and after evaluating the existing system, a new system is proposed. The proposed system consists of various modules; their maintenance works and finally reports generation.
System design refers to the description of a new system based on the information that is collected during the analysis phase and process by which it is developed. It is the creative process of inventing and developing new inputs, database procedures and outputs to meet the system objectives. System design builds on the information gathered during system analysis. It describes what output is to be produced, in what format, what input should be fed to obtain the required output, format of input etc. system design is a part of system development process.

System design encompasses the following steps:
• Review of appropriate data
• Determining requirements for a new system
• Design the new system


Input Design
Input design is the phase where user originated input is converted to computer based format. It includes determining record media, methods of input, speed of capture and entry into system. The goal of designing input data is to make data entry easy as well as free from errors as far as possible.
Thus the objective of designer is to achieve the highest possible level of accuracy and ensure that the input is acceptable and understood by user and staff. A formatted form of data entry is provided which requests the user to enter data in appropriate location.
The main objectives that guide input design are as follows:-

Controlling the amount of input – if the amount of input is high, then more people will be involved, thus increasing chances of error and extra cost. By decreasing the amount of input needed ie; by controlling it, both cost as well as errors can be reduced.
Avoiding delay – During data entry or data preparation, bottlenecks can arise that lead to processing delays. Input should be so designed that it does not lead to bottlenecks and thus avoid processing delays.
Avoiding errors in data – Errors in data can lead to delays and inconsistency. Input design should be such that the data being entered should be free from errors to maximum possible limit.
Avoiding extra steps – More the number of steps more is the chance of error. Thus, number of steps should be kept to minimum.
Keeping the process simple – The process should be kept simple as possible to avoid errors.
The goal of input design is to make data entry as easy, logical and free from errors as much as possible. It involves the identification of required data, capturing and preparing data for computer processing and ensuring correctness of data.

The following features are incorporated into the system:-
Menu Design- The system is menu driven. This simplifies computer data access or entry. Instead of remembering what to enter, the user chooses from the list of options by positioning cursor approximately.
Easy Data Input- Data about screens have been designed in a manner similar to source documents. Approximate messages are provided which prompts the user in entering right data. Erroneous data inputs are checked at the end of each screen itself.
Data Validation- The input data is validated to maximize errors in data entry. For certain data specific codes have been given and validation is done which enable users to enter required data or correct them if they entered wrong codes. Eg:-Numeric entry.
User Friendliness- User is never left in a state of confusion as to what is happening instead approximate error and acknowledgement messages are sent.
Consistent Format- A fixed format is adopted for displaying title and message. For entering data also a fixed format is adopted. For Eg:-when a new customer enters his details, he will be issued his account number. All the details about the customer will be entered into the table.

Output Design

Requirements specify capabilities that a system will be provided in order to solve a problem.
The basic requirements of the output design are as follows:-
• The Output must be accurate.
• The Output must be consistent.
• The output must contain the whole information expected.
• The output must be presented in an acceptable format.
• The output must be easily understandable.
