Project Selection of our group is - Design and Implementation of Educational System Services Grid Istio architecture. This week we conducted a preliminary database design and requirements analysis. Educational system and students learning lives, we each semester frequent use of various functions of the educational system. We demand the beginning of the analysis group design student course selection, performance query. After the exchange with teachers and fellow students, we found a misunderstanding of their own design - only for our students to use educational system has been designed, while ignoring the other roles such as teachers.
Results in increased design entry, information maintenance functions, such as the role of the teacher after, another question arises - how to distinguish between students, teachers and give them two different roles of power? According to the knowledge database to learn, we have designed the role of the administrator, the administrator can authorize teachers, students, making it see a different interface with different permissions, use different functions. Now add the administrator, the administrator of the role we function has been designed, namely adding a notification management (including notification and release modify, query), course management (including input and revision courses), course management (including Course presets and settings) function. We demand complete database design after the analysis is almost completed. As a starting point for requirements engineering software engineering life cycle of software development is the basis for the subsequent phase. Software requirements is a software development objective, but also an important factor in the development of its project success and failure. So demand analysis is reasonable or not, whether the subsequent development of project success has a vital role. Through the needs analysis, and review of the wrong team appeared, the greatest feeling is we need to consider a comprehensive, in many ways to perform requirements analysis and design appropriate database, that is essential to the integrity of the demand when demand analysis.
