Essential Elements

GraphDB uses the following basic elements to store and describe data. Users should know each and how they work together.


An User has access to the system. Depending on the assigned rights the system restricts access to certain functionalities.

User group

An user group is a collection of users. Users may give access to certain data by assigning one or more user groups.


Metadata can be assigned to graphs or graph groups respectively. First users have to create metadata templates. In a second step these templates may be assigned to graphs or graph groups respectively providing a meaningful value.


A Finding element behaves similar to a metadata element. The major difference is semantically. Whereas metadata are used to describe the given data, findings are used to provide results found on the given data.

Graph Group

A graph group is used to collect some graphs and control access to them.


A Graph represents one data set. This is done in a virtually by storing where to find associated binary data. Thus, the same graph may exist in several graphgroups.

Binary data

Binary data elements are stored only once in the database. Graphs only link to these data entities. The user doesn't need to care about uploading binary data. This is automatically done by the system.


For easy referencing, the system supports Quotes. In a quote element you can collect several graphs, graph groups or both.
