# Minor Planet Center Loader #

## Overview ##

This java program provides a way to load the Minor Planet Catalogues provided by the Minor Planets Center into a database.

Currently there are sql scripts and dependencies set up for PostgreSql. Pull requests for other databases are welcome.

## Prerequisites ##

* Java

* Postgresql

## Setup ##

At the moment there are no prebuilt distribution packages available so you will need to build the tool your self. It is not difficult just follow the steps below.

First clone the code and build it.

```

$ cd /tmp

$ git clone [email protected]:wselwood/MPCLoader.git

$ cd MPCLoader

$ ./gradlew distTar

```

At this point you will need to use the sql script in MPCLoader/sql/postgresql-install.sql to create the table in your database.

Next you need to unpack the distribution package that you just built.

```

$ cd 

$ tar -xvzf /tmp/MPCLoader/build/distributions/MinorPlanetLoader-1.0.tar

$ cd MinorPlanetLoader-1.0

```

Now set up your connection details for your database in the connection.properties file

Finally you can run the program by calling

```$ bin/MinorPlanetLoader ```

## Minor Planets Center ##

The data files this is designed to load are created by the minor planets center and can be found at the following two locations:

* http://www.minorplanetcenter.net/iau/MPCORB.html

* http://www.minorplanetcenter.net/iau/ECS/MPCAT/MPCAT.html

## Connecting to a different database ##

To connect to a different brand of database you will need to add the JDBC driver to the dependency list in the build.gradle file. Look for where the postgresql one is and add it there.

Then modify the connection properties with the required strings for your database. Examples should be with the documentation for your JDBC driver.

Finally you will need to port the sql table creation command from the sql/postgres-install.sql file to create the table.

## Notes on usage ##

The table creation does not put any indexes on to the table. I recomend not creating any needed indexes until after all the data has been loaded into the database.
