Kirana best price delivery application

Problem to solve: People have to go to multiple shops for checking best price. Then, they buy stuff they needed and wait for an auto/rikshaw to bring those goods home. They often need to go to multiple shops for different items

1. Buyer builds an order list and places the order from a mobile device
2. XYZ receives the order and finds optimal prices/shops to buy those items
3. XYZ sends "order picking boys" to gather items by pooling items from different orders
4. "order picking boys" bring items to XYZ warehouse where they pack each order
5. "order delivery boys" deliver orders, bring cash
6. XYZ gets feed from local big shops and distributors containing item prices for that day
7. XYZ and distributors settle finances later by reconciling transactions

Spec for small business class management mobile application

I got an idea to build a mobile application that can keep of track of classes, students and their payments for my daughter's music teacher. Here are some major usecases I can think of:

Manage classes:
- add new class for a specific time of day, set its recurring properties. Ex: Every Thursday at 7PM
- change an existing class
- delete an existing class
- set max students in a class
- track progress of the student
- show progress of things student can do vs things need to learn/master

Manage fee payment:
- mark student as paid
- browse a list of unpaid students

Manage enrollment into classes
- add/remove/find a student in a class

Generate reports
- who did not pay this month?

Nice to have:
- automatically adds public holidays
- preference to send reminder to students email if schedule changes
- change schedule for a particular occurrence of a recurrent class
- show picture of the student and his/her contact information

Rewards API - for retail customer loyalty

Below is a spec for Rewards API for customer loyalty programs I came up with. The idea is to keep track of customer purchases by providing them with a store specific card and offer them a financial reward (such as 10$ for every 100$ spent in a month) in return of their spending at the store.

This API can be exposed as a SOAP or other remoting technology and integrated into POS systems.

Key usecases:
1. Customer enrolls in to loyalty program
2. Customer purchases are recorded and points get accumulated
3. Customer redeems rewards points accumulated in his account
4. System clears points accumulated that were not used at the end of every month

Data Model:
Customer_Card
Cardid--firstName--lastName--address--enrollDate

Card_Points
cardId--points--expirationDate
123 80 3/31/2013

Card_Purchases
cardId--purchaseDate--grossAmount
123 3/5/2013 45.0$

Points_Multiplier
pointsMultiplier
0.25

Rewards_Points
points--rewardAmount
100 10$

Application Programming Interface (API) Specification
Integer enrollCustomer(Customer)
void deleteCustomer(int cardId)
void updateCustomer(int cardId, Customer customer)
Customer getCustomer(int cardId)

Double getPointsBalance(int cardId)
Double getPointsMultiplier()

Double addPoints(cardId, purchaseAmount)
Double redeemPoints(cardId)

Business Rules:
- Points expire at the end of every month
- Points_Multiplier specifies how many points there are for 1$
- Rewards_Points specifies how many dollars are rewarded for points
