To accomplish the work in the agreed timeline, we would need to work closely to nail down the scope and requirements.
Post this a quick draft of requirements and high level design database shall be submitted.
After understanding of requirements and high level design has been reviewed, database shall be designed in MySQL.
Testing shall be performed on the DB designed. During UAT, detailed documentation / walkthrough of the database shall be done. Once UAT is successful, then only delivery of the DB shall be considered to complete.
Although this is a small project, intent will be to follow SDLC and do a check at all the important stages / toll gates.
