End of last week, the final examination was done in our University. I checked the exam since this morning. Deign of Object, we discuss the data type of object.
Before design the system, three data models have to think. Logical data modeling are composed by process and Data requirements then, create logical data model. Physical data modeling are composed from Technical requirements and performance requirements. Then, create physical data model. Then, finally, Business data will be create/Update data. This becomes actual data. Data Oriented Modeling was defined by three data models.
The system design, Analysis comes from application requirement of data. Then, implement the data to system as design work.
Recently software development, Rapid-application development (RAD) is a general term, used to refer to adaptive software development approaches, as well as the name for James Martin's approach to rapid development. In general, RAD approaches to software development put less emphasis on planning and more emphasis on an adaptive process. Prototypes are often used in addition to or sometimes even in place of design specifications.
RAD is especially well suited for (although not limited to) developing software that is driven by user interface requirements. Graphical user interface builders are often called rapid application development tools. Other approaches to rapid development include the adaptive, agile, spiral, and unified model. We recommend RAD for timely development project,
After completed the software development, design the system support policy is very important to achieve the sustainability. Data from outside is very dynamically changed and its requirement of system from business aspects were updated. Therefore, system maintenance and support policy should be flexible and has to have an agility manner.
We design any different type of block chain DEX APP so far and its requirement were changed by the stakeholders. Some part of code may transfer to RPA module. We should consider the design of program by units level.
