• PostgreSQL
• Maven

Getting Started

To get a local copy up and running follow these simple steps.

Prerequisites

1. Download and prepare the data

   • Go to https://exoplanetarchive.ipac.caltech.edu/docs/data.html
   • Select the Planetary Systems Composite Data Table
   • Under the 'Download Table' option: select CSV Format and Download all Columns/all Rows
   • Open the file and remove column description information and rename the 'rowid' column to 'id'
   • Note: you'll have to update the schema.xml file with the path and filename

2. Setup the DB (if you choose something other than PostgreSQL, you will need to tweak the Schema SQL language)
