We are planning an mobile application.
Before start to develop client apps we want to have confirmed database schemas.
Due to database schema need to be designed according to a certain logic and algorithm and simulated for efficiency, we hope to find a db design expert first.
After db, we will proceed to server side app and client app.
For some reasons we will use a similar model to describe real project.
For example,
art-craft rating system
1. logic to rate participant (art-craft)
- a rating set consists of several art-crafts
- raters set ranking order from top to bottom in a rating set
- participant gets score according to the ranking in a rating set
- participant gets ranking by score
- rater’s rating accuracy is applied to score leverage
- participant gets a certain grade by ranking
2. logic to to rate rater's rating accuracy
- rater get score according to his/her rating accuracy
- rating accuracy is calculated by comparing his ranking order to final ranking order
(there will be time interval between two)
- rater gets grade by own score
3. logics to be applied when compose a rating set when assign a rating set to raters
- random composition and assigning
- 1 rating set to multiple raters
- geographical information
- (normal) within an equal grade or certain rule
- (option) participants can challenge a certain grade, contest, ranker
Could you answer me how many tables do you expect to satisfy conditions above?
If you think it is proper to use mix of rdb and nosql then give me your brief idea.
Proposal with no answer will be regarded as spam.
After successful completion of db design above, additional job will be discussed.
