# CODI Schema

This project reads in the [PCORnet Common Data Model v6.0 Parseable Spreadsheet Format](https://pcornet.org/wp-content/uploads/2021/11/2021_11_29_PCORnet_Common_Data_Model_v6dot0_parseable.xlsx) and will create database tables to represent the CDM.

This application is written in Ruby and it uses the [Sequel](http://sequel.jeremyevans.net/index.html) library to generate the appropriate DDL.

This script currently creates the tables, sets not null constraints and primary keys. It does not yet handle creating the foreign key relationships.

**Note** The CSV files were created using Excel to open the parseable file and then perform an export to CSV. Excel will put a Byte Order Marker (BOM) in the file, which throws off the standard ruby CSV parsing library. The CSV files were re-encoded to UTF-8 using Visual Studio Code.

## Prerequisites

This was built using ruby 2.6.2. It used inline [Bundler](https://bundler.io/) to manage dependencies. Assuming you have ruby installed, you can:

    gem install bundler

## Running

The connection information exists in the ruby file: `build_db.rb`:

```

DB = Sequel.connect(adapter: 'postgres', :host => 'localhost',

  :database => 'codi',

  :user => 'codi',

  :password => 'codi')

```

Change these values as appropriate to point to your database instance. The following adapters should be supported: `postgres`, `mysql`, `oracle`, `mssql`

To create the schema, just run the script:

    ruby build_db.rb

It assumes that the database has been created and is empty. It will create all of the columns after that.

### Postgres

The Postgres user must have `CONNECT` and `CREATE` privileges in order for this script to run successfully. A user can be granted these scopes with:

```sql

GRANT CONNECT ON DATABASE codi_db TO codi;

GRANT CREATE ON DATABASE codi_db TO codi;

```
