An exchange object represents an actual exchange of currency, which can occur in the Ripple Consensus Ledger as the result of executing either an OfferCreate transaction or a Payment transaction. In order for currency to actually change hands, there must be a previously-unfilled Offer previously placed in the ledger with an OfferCreate transaction.

### Dependencies ###
The Historical Database requires the following software installed first:
* [PostgreSQL](http://www.postgresql.org/) (required for v1),
* [HBase](http://hbase.apache.org/) (required for v2),
* [Node.js](http://nodejs.org/)

### Installation Process ###
For v1 (postgres):
1. Create a new postgres database:
`createdb ripple_historical` in PostgreSQL
2. Clone the rippled Historical Database Git Repository:
`git clone https://github.com/ripple/rippled-historical-database.git`
(You can also download and extract a zipped release instead.)
3. Use npm to install additional modules:
`cd rippled-historical-database`
`npm install`
The install script will also create the required config files: `config/api.config.json` and `config/import.config.json`
4. Modify the API and import config files as needed. If you only wish to run the v1 endpoints, remove the `hbase` section from the api config.
5. Load the latest database schema for the rippled Historical Database:
`./node_modules/knex/lib/bin/cli.js migrate:latest`
For v2 (hbase):
