A distributed system architecture with components each having an autonomous “hub” or dependent “hub” and a related differential indexing method for obtaining data are disclosed.
Claims3
A computer executed method for data storage, comprising:
- defining a relationship type, the relationship type being of the form “entity 1_has_relationship_to_entity 2” wherein “entity 1”, “has”, “relationship”, “to”, and “entity 2” are elements of the type;
- assigning each element a number indicating the sequential position of the element in the type relative to other elements in the type;
- defining at least one allowed search for instances of the type based on the numbers indicating the sequential positions;
- identifying all instances of the relationship type that are resident in available data and that satisfy the defined search;
- and
- adding the instances to indices prior to executing a query for data.
