Latona

Latona is the DW/BI solution accelerator which simplifies model-based code generation.

With this project, we're building a tool that allows generating all code artifacts required to spin off an end-to-end data warehouse/data platform. Such artifacts might include:

• Database projects (staging and public areas of a DW)
• ETL code for the selected technology
• MPP artifacts
• Model documentation
• Any other thing that can be templated

We believe that code generation should be driven by a data model containing a list of tables, fields and some metadata.

Quick start

Prerequisites

Download and install:

• Node JS

npm install -g latona
npm link

3. Use npm to install required addon packages (refer to this page for the complete list), for example:

npm install <package-name>

Use

1. Create new model and project:

latona new model

2. Adjust model content and project settings as needed - read this tutorial to get more details

3. Validate your project:

latona validate

4. Render your artifacts:
