1. A database computer system comprising a context-based graph-relational intersect derived (CB-GRID) database, wherein the CB-GRID database associates a real entity graph node to a synthetic entity graph node, and wherein the CB-GRID database in the database computer system comprises: one or more processors, wherein said one or more processors implement the CB-GRID database; a real entity graph node, wherein the real entity graph node identifies a real entity, and wherein the real entity graph node comprises a pointer to a primary key in a first tuple that non-contextually describes the real entity; a primary relational database, wherein the primary relational database comprises the first tuple that non-contextually describes the real entity, and wherein the first tuple contains the primary key; a context relational database, wherein the context relational database comprises a second tuple that contains a foreign key that matches the primary key in the primary relational database, and wherein the second tuple dynamically describes a context of data in the first tuple; a contextual entity relational database, wherein the contextual entity relational database comprises a third tuple that contains data from the first tuple and the second tuple, and wherein the third tuple comprises a contextual tuple key; a synthetic entity graph node, wherein the synthetic entity graph node is linked to the contextual entity relational database by the contextual tuple key, wherein the synthetic entity graph node describes a synthetic entity that is described by data in the contextual entity relational database, and wherein the contextual entity relational database links the real entity graph node to the synthetic entity graph node, wherein the real entity is a physical machine, wherein the synthetic entity graph node describes a software-modeled machine that is operating outside of nominal parameters, and wherein the CB-GRID database in the database computer system further comprises: output data from a sensor on the physical machine stored in the first tuple; model type data describing a model type of the physical machine stored in the second tuple; and software-modeled machine descriptor data stored in the third tuple, wherein the contextual entity relational database links the physical machine to the software-modeled machine that is operating outside of the nominal parameters.
