A modelling method of software configuration change control

Software configuration management is a group of activities to build a system configuration by gathering configuration items generated during the lifecycle of a software system and to manage systematically changes to the system configuration. We build a model of configuration change control activity at each phase of the software development life cycle. Each model is represented in an entity relationship modelling method. We make an integrated ER model of configuration change control by merging the models of life cycle phases. When the ER model is completed, an IRD schema, which is a IRDS model, is generated from the ER model using IRDS commands.
