Abstract

ODIN is a system developed by Western Electric to automate the construction of electronic form entry, processing, and retrieval systems. An important component of ODIN is SEDL, the language used to define the logical structure of forms and the integrity constraints that each form must pass as it is entered. SEDL is a powerful, concise end-user language. Its integrity constraints are sophisticated assertions which are combined by using standard programming language constructs. Lists on forms are considered to be relations in a miniature relational database, and data manipulation language constructs are used to specify constraints involving them. SEDL's expressive power has been more than adequate for the complex office applications that have used it.
