The present invention discloses a workflow system for managing versions of a document, which can manage a variation history of the document and minimize the stored data of the document, and a method for managing versions of a document using the same. The workflow system includes the workflow engine, which consists of a flow control module for generating a control command according to a command from a client computer or self operation, a DB storage module for storing process definition defined in the client computer and information on a document file stored in an EDMS server in a database, and a file management module for calling a function for managing the document file from the EDMS server, and the adapter module for interface between the workflow engine and the EDMS server. The EDMS database for the workflow system stores the document file by using an extensible markup language, and the workflow engine compares a before-correction document with an after-correction document, stores the corrected document file in the EDMS database by using XML tags, and generates a final document file by combining the before-correction document file and the corrected document file, thereby minimizing the data storage of the document.
