What are my options

[dorandoran]

I have a code that calls web services api and grabs data from a table.

Goal:
1. I need to store these data somewhere locally or in the memory.
2. I am going to need to grab data from 4 different table and later join them to create some records.

Challenges:
1. How am I going to store the data? because i am using .net form where user will click a button and there is not backend database connection.
2. How can I then join all four dataset that I just grabbed? and make a complete new dataset?

Any assist will be helpful

Thanks

You can store them in memory as a DataTable object (or as a DataTable inside a DataSet)

Not sure if you can perform joins on tables in memory or not, but it might be possible with like a DataAdapter or something?

Is there any links or something that I can follow? I have never done this before.

Google is your friend.
This is something I found (on Google, no less) that should help you learn how to use a DataTable.
