One way is creating IBM Db2 Warehouse on Cloud. This database will be hosted on the cloud. However, if you perfer to have your database on premise or locally, we can all use the Db2 Docker Image.

+Now that we have created our databases, we need to import the data from the csv file into our database. We will be creating a schema called `DB2WML`. The two tables we will create are `HOME_SALES` and `HOME_ADDRESS`. `HOME_SALES` will store the data we retrieve from our csv file. `HOME_ADDRESS` is going to be the addresses associated with each home.
