Software maintenance and user interface design (soft work video summary)

Software Maintenance is the final stage of software development, but also the longest stage, not to be underestimated! the Human, material and financial resources spent on software maintenance account for a large part of the software development cycle.

Software Maintenance White is a process that modifies software after it has been put into use, to meet the new needs of the user or to discover new vulnerabilities.

The purpose of the software maintenance is: 1, modify the error. 2, increase the function and performance of the software. 3. Make the software more adaptable to the times and prolong the service life. 4, so that the software can better serve the serving.

The types of software maintenance include: 1, adaptive maintenance 2, Integrity maintenance 3, corrective maintenance

Adaptive maintenance is to adapt to the development of the software to adapt to the external conditions and changes in the environment to make the corresponding changes.

Perfect maintenance in order to meet the user's new requirements, the software to improve the modification.

Corrective Maintenance is the solution to the potential problems of software, to ensure that they can better serve the service.

Software maintenance is an essential part of software development, since it is the future work, then for future convenience, we have to write the document well, in order to maintain more clear ...

The following is the user interface design. The user interface design should have the characteristics, you can imagine is: the usability, flexibility, complexity and reliability

User interface design is not done in the final stages of software development, but it begins when the system needs analysis. We need to analyze the user's characteristics, analyze the work, to determine the type of user interface, to carry out related design.

The task model consists of both static and dynamic. The static model of the system is the object-relation model, which is used to show the structure design of the interface. A dynamic model is a description of the dynamic behavior of an object that is related to a system operation or a session design.

In each task, the actions are assigned to computers, users, or both. In general, users assume the task of creating, judging and exploring, while the computer undertakes the task of repeating inspection, computation and data processing. The two have a clear division of labor and complete a task.

In general, user interface design, is wholeheartedly for the user's sake, analysis of the characteristics of users, and then to better human-computer interaction.
