Create Database Schema with Prototypical City Data (simmobcity)

Steps to create Database

1. Download the simmobcity archive file from this link and save it on the Postgres server
2. Create a new database (i.e. simmobcity) in postgres
3. Ensure access is granted to the new database by checking the pg_hba.conf file. If required, include the new database in pg_hba.conf file and restart postgres.
4. At the terminal prompt of the Postgres server, change directory to the path containing the downloaded archive file
5. Enter the following command to restore the database schema and data
   pg_restore -U postgres -h localhost -O -x simmobcity.archive.20181205 -d simmobcity

Documentation on the pg_restore command can be found here.

Create Database Schema (without data)

Follow the same steps as above. For step 5, use the -s or --schema-only option in the pg_restore command.
pg_restore -U postgres -h localhost -O -x -s simmobcity.archive.20181205 -d simmobcity
