- A web app which accepts multiple sets of location points in the form of :-
- coordinates
- area names
- marker
- Plots them on a Google Map/Bing Map
- Find the shortest path which connects all the points and display that on the same map.
- Also a screen that displays the logs of all the previously computed routes.

Before you get started with using PostgreSQL, you'll have to install it. Follow these steps to get started:
-
There are a couple of ways to install PostgreSQL. One of the easier ways to get started is with Postgres.app. Navigate to http://postgresapp.com/ and then click "Download":
-
Once it's finished downloading, double click on the file to unzip then move the PostgreSQL elephant icon into your
applicationsfolder. Double click the icon to launch the application. -
You should see a new window launched that says "Welcome to Postgres". If it says that it cannot connect to the postgres server this means that the DEFAULT port is probably already in use. Make sure you don't have any other instances of Postgres on your computer. Uninstall them if you do and then resume with these steps. Click on the button that says "Open psql":
-
Postgres.app will by default create a role and database that matches your current macOS username. You can connect straight away by running
psql. -
You should then see something in your terminal that looks like this (with your macOS username in front of the prompt rather than 'postgres'):
-
You should now be all set up to start using PostgreSQL. For documentation on command line tools etc see http://postgresapp.com/documentation/
Digital Ocean have got a great article on getting started with postgres. A quick summary is below.
sudo apt-get update
sudo apt-get install postgresql postgresql-contrib
By default the only role created is the default 'postgres', so PostgreSQL will only respond to connections from an Ubuntu user called 'postgres'. We need to pretend to be that user and create a role matching our actual Ubuntu username:
sudo -u postgres createuser --interactive
This command means 'run the command createuser --interactive as the user called "postgres"'.
When asked for the name of the role enter your Ubuntu username. If you're not sure, open a new Terminal tab and run whoami.
When asked if you want to make the role a superuser, type 'y'.
We now need to create the database matching the role name, as PostgreSQL expects this. Run:
sudo -u postgres createdb [your user name]
You can now connect to PostgreSQL by running psql.
-
To start PostgreSQL, type this command into the terminal:
psql -
Next type this command into the PostgreSQL interface:
CREATE DATABASE test;
NOTE: Don't forget the semi-colon. If you do, useful error messages won't show up. -
To check that our database has been created, type
\linto the psql prompt. You should see something like this in your terminal:
-
If you closed the PostgreSQL server, start it again with:
psql -
To create a new user, type the following into the psql prompt:
CREATE USER testuser;
-
Check that your user has been created. Type
\duinto the prompt. You should see something like this:
Users can be given certain permissions to access any given database you have
created. -
Next we need to give our user permissions to access the test database we created above. Enter the following command into the
psqlprompt:GRANT ALL PRIVILEGES ON DATABASE test TO testuser;
