Entity Relation Diagram ([link](https://lucid.app/lucidchart/b2de3990-e4b0-4b2f-8553-d5946f50834e/edit?viewport_loc=-208%2C-333%2C2102%2C1372%2C0_0&invitationId=inv_f34f8d5b-dfa7-49b7-b8d1-8d7d8303c194) to Lucidchart)
## Schema
Refers to the database schema in the [schema.pdf](docs/schema.pdf) file.
## Database
This project uses SQLite as the database. To use the database, clone this repository, navigate to the queries directory, and run the following commands in the terminal:
1. Initialize a new database with the schema:
```bash
sqlite3 database.db < schema.sql
```
2. Populate the database:
```bash
sqlite3 database.db < data.sql
```
3. To run queries on the database, use the following command. Change the number in the query file name to run different queries:
```bash
sqlite3 database.db < query1.sql
```
4. To confirm that the tables were created and conform to the constraints, refer to the [ddl_outputs.pdf](docs/ddl_outputs.pdf) file.
5. To view example outputs of the queries, refer to the [dml_outputs.pdf](docs/dml_outputs.pdf) file.
## Web Application
The web application implements the Employee and Customer tables. It is built using Node.js and Express.js. To run the web application, clone this repository, navigate to the webapp directory, and run the following commands in the terminal:
1. Install the required packages:
```bash
