Design is multi-step process that focuses on data structure software architecture, procedural details, (algorithms etc.) and interface between modules. The design process also translates the requirements into the presentation of software that can be accessed for quality before coding begins.
Computer software design changes continuously as new methods; better analysis and broader understanding evolved. Software Design is at relatively early stage in its revolution.
Therefore, Software Design methodology lacks the depth, flexibility and quantitative nature that are normally associated with more classical engineering disciplines. However techniques for software designs do exist, criteria for design qualities are available and design notation can be applied.
INPUT DESIGN
Input design is the process of converting user-originated inputs to a computer-based format. Input design is one of the most expensive phases of the operation of computerized system and is often the major problem of a system.
OUTPUT DESIGN
Output design generally refers to the results and information that are generated by the system for many end-users; output is the main reason for developing the system and the basis on which they evaluate the usefulness of the application.
The output is designed in such a way that it is attractive, convenient and informative. Forms are designed in VB.NET with various features, which make the console output more pleasing.
As the outputs are the most important sources of information to the users, better design should improve the system’s relationships with us and also will help in decision-making. Form design elaborates the way output is presented and the layout available for capturing information.
DATABASE DESIGN
The database design is a must for any application developed especially more for the data store projects. Since the chatting method involves storing the message in the table and produced to the sender and receiver, proper handling of the table is a must.
In the project, login table is designed to be unique in accepting the username and the length of the username and password should be greater than zero. Both the company and seeker username are stored in the same table with different flag values.
The job and question table is common to all companies. Likewise job apply details are stored in the common ‘apply’ table. The different users view the data in different format according to the privileges given.the complete listing of the tables and their fields are provided in the annexure under the title ‘table structure’.
