i do not know how to load source system in SQL - sql-server

Question

This is my task list:
Design a star or snowflake schema for a data warehouse that will help answer various business questions regarding sales.
Create a database in SQL Server (this is the data warehouse server) based on the star/snowflake schema you designed.
Load data from the source system i.e. the OLTP database shown earlier to the star/snowflake schema database.
The data from most of the tables in the OLTP database have been prepared in a form of SQL statements. Unfortunately, due to company's policy, you are not allowed to load data from the Products and Customer table 'directly'.
The Customer data has been prepared in CSV format
The Product data can only be retrieved from cloud database in JSON format http://bi.edisonsiow.com/ay1516s2/ca1/getProducts.php
You are required to find the most efficient way, which might include coding, to load data from the sources to your SQL Server.
So far i have done this :

I dont know how to load from source system?

Answer 1

In SQL Server Management Studio, exp[and the server-name, and under databases, find your database.
Right-click it, select Tasks, and then Import Data.
Use the import/export wizard to assist you in importing data from your source data.
