A data structure for representing information as a binary directional graph comprising a set of points connected by three distinct types of directed edges. Each point must have a unique left (parenting) edge and a unique right (parenting) edge with end points, and an identity edge that can be null (i.e. have no end point). All connected paths of edges upwards eventually converge at a maximal point in the structure. The points are uniformly assigned a fixed set of data as their content. Rules are defined to construct the structure and allow representation of information, with methods described for translating conventional forms of representation, such as tables, properties, classes, relations, and functions. The structure can be represented as a single relation (i.e. a single table with a fixed structure) and can be implemented using a conventional relational database.
