Text, image, graphics editor

The editor proposed in this study can manipulate textual, graphics and image data in a unified way. Each data type can be edited individually or dependencies can be set up between various data items so that modifying one might propagate its effects on others. The system is developed by using new software tools and techniques such as object oriented programming, multi window workstations running with event selection principles and iconic interfacing. Facilities for data protection, such as journaling are provided. Data storage and editing principles are handled within guidelines of well established standards. However, where such definitions fall short, proposals for new techniques are made especially with respect to relation sets binding various data types
