Gstore System(also called gStore) is a graph database engine for managing large graph-structured data, which is open-source and targets at Linux operation systems. The whole project is written in C++, with the help of some libraries such as readline, antlr, and so on. Only source tarballs are provided currently, which means you have to compile the source code if you want to use our system.

The formal help document is in Handbook.

This system is really user-friendly and you can pick it up in several minutes. Remember to check your platform where you want to run this system by viewing System Requirements. After all are verified, please get this project's source code. There are several ways to do this:

• download the zip from this repository and extract it

• fork this repository in your github account

• type git clone [email protected]:Caesar11/gStore.git in your terminal or use git GUI to acquire it

Then you need to compile the project, just type make in the gStore root directory, and all executables will be ok. To run gStore, please type bin/gload database_name dataset_path to build a database named by yourself. And you can use bin/gquery database_name command to query a existing database. What is more, bin/gconsole is a wonderful tool designed for you, providing all operations you need to use gStore. Notice that all commands should be typed in the root directory of gStore, and your database name should not end with ".db".

If you want to understand the details of the gStore system, or you want to try some advanced operations(for example, using the API, server/client), please see the chapters below.

• Basic Introduction: introduce the theory and features of gStore

• Install Guide: instructions on how to install this system

• How To Use: detailed information about using the gStore system

• API Explanation: guide you to develop applications based on our API

• Project Structure: show the whole structure and sequence of this project
