6. A computer-implemented method of providing document data from a document management system for display on an interface of a computer system through an enabler application that manages associations between fields of a host application and fields of documents in the document management system, comprising: displaying the host application on the interface of the computer system that includes one or more data processors and one or more non-transitory computer-readable mediums including instructions for commanding the one or more data processors, wherein the host application includes an interface field that is linked to a document field of documents in the document management system; capturing a field value for the interface field and an operation identification from the host application using the enabler application on the computer system, wherein the field value entered in the host application is captured at the enabler application without receiving any communication from the host application; accessing a context rule in a context rule database using the computer system based upon the operation identification, wherein the context rule identifies a type of document that is relevant to the identified operation; querying the document management system using the computer system based on the field value that is captured from the interface field of the host application and the relevant document type identified by the context rule that is accessed based on the operation identification from the host application; receiving document data from the document management system based on said querying using the computer system; and updating the interface of the computer system based on the document data.
