Previous requirements

• Linux based OS or WSL, and execute the commnads from a bash commnad line.
• Docker (Get Docker)
• Docker Compose (Get Docker Compose for Linux users)

SQL part

Command to create postgres data base with docker

A PostgreSQL database is needed for running the SQL queries and views. First, get the latest postgres image from docker.

docker pull postgres:latest

Then, run the following command:

docker run -d --name TPO_postgres -e POSTGRES_PASSWORD=admin -e POSTGRES_USER=admin -e POSTGRES_DB=VDR -p 5432:5432 postgres

Command to load tables and inserts

In order to insert the data provided by the course chair, run the following commands.

docker cp ITBA_2023_esquema_facturacion-2.sql TPO_postgres:/load.sql
docker exec -it TPO_postgres psql -U admin -d postgres -a -f /load.sql

Run API

In order to start the API, first run

npm install

Then start the API

node .

The API is available at localhost:3000. Making a get request at / will provide the documentation of the main endpoints of the API. Furthermore, there are "secret" endpoints that run the queries and create/query the views.

• GET at -> localhost:3000/queries/[number of query]
• POST at -> localhost:3000/view/[number of view] Creates the view
• GET at -> localhost:3000/view/[number of view] Select * number_view

Deployed API

The API is deployed and accessible at martinippolito.com.ar:3000. The data is already inserted, and shares the same endpoints.

NoSQL part

Run API

In order to start the API, located in the directory NoSQL_API/, first run

cd NoSQL_API
npm install

Then start the API

node .

The API is available at localhost:3001. Making a get request at / will provide the documentation of the main endpoints of the API. In this case, there are no endpoints that run the queries and create/query the views for the NoSQL part.

Deployed API

The API is deployed and accessible at martinippolito.com.ar:3001. The data is already inserted, and shares the same endpoints.

Migration

In order to migrate the data given by the course chair, the following steps must be followed.

Note: We will create a new postgres container, so if you have created one before in the 'SQL part' stop it with the following command:

docker stop TPO_postgres

Create postgreSQL and mongoDB docker containers

From the repository's root

cd ./compose
docker compose up

Make sure there are no postgreSQL nor mongoDB database already up

Now, the data is inserted in the postgreSQL, but not in the mongoDB

Migrate to mongoDB

From the repository's root

cd ./sqlMigrator
chmod u+x ./migrator.sh
./migrator.sh postgres_TP mongo_TP

It is possible to get this error: bad interpreter: No such file or directory. In that case just run (install 'dos2unix' if needed) the following:

dos2unix migrator.sh
