# Data Models SQLAlchemy

[![Circle CI](https://circleci.com/gh/chop-dbhi/data-models-sqlalchemy/tree/master.svg?style=svg)](https://circleci.com/gh/chop-dbhi/data-models-sqlalchemy/tree/master) [![Coverage Status](https://coveralls.io/repos/chop-dbhi/data-models-sqlalchemy/badge.svg?branch=master&service=github)](https://coveralls.io/github/chop-dbhi/data-models-sqlalchemy?branch=master)

SQLAlchemy models and DDL and ERD generation for [chop-dbhi/data-models-service](https://github.com/chop-dbhi/data-models-service) style JSON endpoints.

Web service available at http://dmsa.a0b.io/

## SQLAlchemy Models

In your shell, hopefully within a virtualenv:

```sh
pip install dmsa
```

In python:

```python
from sqlalchemy import MetaData
from dmsa import make_model_from_service

metadata = MetaData()
metadata = make_model_from_service('omop', '5.0.0',
                                   'http://data-models.origins.link/',
                                   metadata)

for tbl in metadata.sorted_tables:
    print tbl.name
```

These models are dynamically generated at runtime from JSON endpoints provided by chop-dbhi/data-models-service, which reads data stored in chop-dbhi/data-models. Any data model stored there can be converted into SQLAlchemy models. At the time of writing, the following are available.

CAVEAT: The models are currently "Classical"-style and therefore un-mapped. See more information [here](https://github.com/chop-dbhi/data-models-sqlalchemy/issues/22).

- i2b2
    - 1.7.0
- i2b2 for PEDSnet
    - 2.0.1
- OMOP
    - 4.0.0
    - 5.0.0
- PCORnet
    - 1.0.0
    - 2.0.0
    - 3.0.0
- PEDSnet
    - 1.0.0
    - 2.0.0
    - 2.1.0
    - 2.2.0

## DDL and ERD Generation

Use of the included Dockerfile is highly recommended to avoid installing DBMS and graphing specific system requirements.

The following DBMS dialects are supported when generating DDL:

- PostgreSQL
- MySQL
- MS SQL Server
- Oracle

### With Docker:

Retrieve the image:

```sh
docker pull dbhi/data-models-sqlalchemy
```

Usage Message:

```sh
docker run --rm dbhi/data-models-sqlalchemy dmsa -h
```

Generate OMOP V5 creation DDL for Oracle:

```sh
docker run --rm dbhi/data-models-sqlalchemy dmsa ddl -tci omop 5.0.0 oracle
```

Generate OMOP V5 drop DDL for Oracle:

```sh
docker run --rm dbhi/data-models-sqlalchemy dmsa ddl -tci --drop omop 5.0.0 oracle
```

Generate OMOP V5 data deletion DML for Oracle:

```sh
docker run --rm dbhi/data-models-sqlalchemy dmsa ddl --delete-data omop 5.0.0 oracle
```

Generate i2b2 PEDSnet V2 ERD (the image will land at `./erd/i2b2_pedsnet_2.0.0_erd.png`):

```sh
docker run --rm -v $(pwd)/erd:/erd dbhi/data-models-sqlalchemy dmsa erd -o /erd/i2b2_pedsnet_2.0.0_erd.png i2b2_pedsnet 2.0.0
```

The `graphviz` graphing package supports a number of other output formats, which are interpreted from the passed extension.

### Without Docker:

Install the system requirements (see Dockerfile for details):

- Python 2.7
- `graphviz` for ERD generation
- Oracle `instantclient-basic` and `-sdk` and `libaio1` for Oracle DDL generation
- `libpq-dev` for PostgreSQL DDL generation
- `unixodbc-dev` for MS SQL Server DDL generation

Install the python requirements, hopefully within a virtualenv (see Dockerfile for details):

```sh
pip install cx-Oracle            # for Oracle DDL generation
pip install psycopg2             # for PostgreSQL DDL generation
pip install PyMySQL              # for MySQL DDL generation
pip install pyodbc               # for MS SQL Server DDL generation
```

Install the data-models-sqlalchemy python package:

```sh
pip install dmsa
```

Usage Message:

```sh
dmsa -h
```

Generate OMOP V5 creation DDL for Oracle:

```sh
dmsa ddl -tci omop 5.0.0 oracle
```

Generate OMOP V5 drop DDL for Oracle:

```sh
dmsa ddl -tci --drop omop 5.0.0 oracle
```

Generate OMOP V5 data deletion DML for Oracle:

```sh
dmsa ddl --delete-data omop 5.0.0 oracle
```

Generate i2b2 PEDSnet V2 ERD (the image will land at `./erd/i2b2_pedsnet_2.0.0_erd.png`):

```sh
mkdir -p erd
dmsa erd -o ./erd/i2b2_pedsnet_2.0.0_erd.png i2b2_pedsnet 2.0.0
```

## Web Service

The web service uses a [Gunicorn](http://gunicorn.org/) server in the Docker container and the Flask debug server locally. It exposes the following endpoints:

- Creation DDL at `/<model>/<version>/ddl/<dialect>/`
- Creation DDL for only `table`, `constraint`, or `index` elements at `/<model>/<version>/ddl/<dialect>/<elements>`
- Drop DDL at `/<model>/<version>/drop/<dialect>/`
- Drop DDL for only `table`, `constraint`, or `index` elements at `/<model>/<version>/drop/<dialect>/<elements>`
- Data deletion DML at `/<model>/<version>/delete/<dialect>/`
- ERDs at `/<model>/<version>/erd/`
- Oracle logging scripts at `/<model>/<version>/logging/oracle/`
- Oracle logging scripts for only `table` or `index` elements at `/<model>/<version>/logging/oracle/<elements>/`
- Oracle nologging scripts at `/<model>/<version>/nologging/oracle/`
- Oracle nologging scripts for only `table` or `index` elements at `/<model>/<version>/logging/oracle/<elements>/`

### With Docker:

Usage:

```sh
docker run dbhi/data-models-sqlalchemy gunicorn -h
```

Run:

```sh
docker run dbhi/data-models-sqlalchemy  # Uses Dockerfile defaults of 0.0.0.0:80
```

### Without Docker:

Install Flask:

```sh
pip install Flask
```

Usage Message:

```sh
dmsa -h
```

Run:

```sh
dmsa serve                              # Uses Flask defaults of 127.0.0.1:5000
```
