[Mwesigwa Ezra]

Hello Everyone.
I have an Idea of creating a price comparison mobile app, lately i have been diving deep into the database API, what has really defeated me is how to come up with the database model. All i want is a user to create a shopping list based on the items i have in the database,then the app automatically aggregates prices in different stores based on the user's entered location search! think tanks kindly help

You would need a Create, Query/List or maybe Delete & Update Service for your users further update or delete.

You will let users to type for the information , such as price and products and use the create service to send the data to the database.

You will then show the user back with the price comparison by using query service, by using "where" parameter in your query service request query string.

For example if the user want to find products lower than $10, type this in "where"

code{"price": {"$lt": 10}}/code
($It means "less than" in query service, details at the link above)
(Change "price" to the column name in Your database.)
