## Influx SDK Tutorial Project
### Relevant Article:
- [Introduction to using InfluxDB with Java](http://www.baeldung.com/using-influxdb-with-java/)
### Overview
This Maven project contains the Java code for the article linked above.
### Package Organization
Java classes for the intro tutorial are in the
org.baeldung.influxdb package.
### Running the tests
The test class expects an InfluxDB server to be available on localhost, at the default port of 8086 and with the default "admin" credentials.

Introduction to the OrientDB Java APIs
======================================
This is a simple maven project that shows how to use OrientDB's Java APIs.
### Requirements
- Maven
- Java 7 or higher
- OrientDB
### Build
To build and start the server simply type
```bash
$ mvn clean install
```
### Run Tests
Before launching unit tests:
- Install OrientDB
- Create BaeldungDB, BaeldungDBTwo and BaeldungDBThree databases
- Uncomment annotations on the test files
