19. A system comprising: a device to provide: a data provider to receive a structured query language query, to determine at least one point data query and at least one relational data query based on the structured query language query, to transmit the at least one point data query, and to transmit the at least one relational data query; one or more devices to provide: at least one point data server to receive the at least one point data query and to transmit point data to the data provider in response; and at least one relational data server to receive the at least one relational data query and to transmit relational data to the data provider in response, wherein the data provider is further to join the point data and the relational data into a result rowset; wherein the at least one point data server to receive the at least one point data query and to transmit point data to the data provider in response comprises: at least one point data server to receive the at least one point data query that is based on the structured query language query and to transmit point data, to the data provider, that has been collected from multiple heterogeneous sources based on components defined according to a class-based object model and encapsulated as object instantiations of the components; and wherein the at least one point data server is to receive the object instantiations of the components defined according to the class-based object model; and wherein the point data is current, real-time or value data associated with one or more instruments, components, or portions of a manufacturing, industrial, commercial, or other system.
19. A system comprising: a device to provide: a data provider to receive a structured query language query, to determine at least one point data query and at least one relational data query based on the structured query language query, to transmit the at least one point data query, and to transmit the at least one relational data query; one or more devices to provide: at least one point data server to receive the at least one point data query and to transmit point data to the data provider in response; and at least one relational data server to receive the at least one relational data query and to transmit relational data to the data provider in response, wherein the data provider is further to join the point data and the relational data into a result rowset; wherein the at least one point data server to receive the at least one point data query and to transmit point data to the data provider in response comprises: at least one point data server to receive the at least one point data query that is based on the structured query language query and to transmit point data, to the data provider, that has been collected from multiple heterogeneous sources based on components defined according to a class-based object model and encapsulated as object instantiations of the components; and wherein the at least one point data server is to receive the object instantiations of the components defined according to the class-based object model; and wherein the point data is current, real-time or value data associated with one or more instruments, components, or portions of a manufacturing, industrial, commercial, or other system. 25. The system according to claim 19 , wherein the at least one point data query is separate from the at least one relational data query.
