Levvr is a semantic database with a semantic information model at its core. The word "semantic" meand "meaningful. this means that within levvr, different types of information are interrelated through meaningful relations.
To build a semantic model, we have three building blocks:
Nodes
Fields
Relations
Together, they are all you need to build the model.
An example of a visual representation of a model, as available in levvr, is shown below. This model shows all building blocks and how they make up a model:
The nodes (circles) always represent a certain information type.
The fields (shown as a list) are an intrinsic part of the node and can be of different types. Examples of field types are: text, picklist, Auto ID.
The relations have a semantic meaning, direction and a behaviour and are shown as arrows between two nodes.
