Abstract
Methods, apparatus, and articles of manufacture for accessing process control data involve loading a client object and communicating a data access request from the client object to a real object configured to communicate with a server. The real object then communicates a query to the server based on the data access request and obtains process control data from the server in response to the query. The process control data is then mapped from a first data layout associated with a server schema to a second data layout associated with a client schema. The mapped process control data is then communicated to an application.
