If you are developing a software for online shopping, then which decision table you will create to implement your logic?
Table consists of seller behavior
Table consists of workers’ salary
Table consists of Discount rules
Table consists of workers’ commission
The responsibility of ensuring that the enhancements made by the software team do not have an effect on the software used in production lies with the system administrator. Since the software development life cycle (SDLC) is so short in the program that is being updated, new features need to be added as rapidly as possible. These modifications need to be sanctioned first before they can be put into action. Before beginning the upgrade process, it is important to have a discussion about the four possible strategies that might assist limit production downtime.
