The Design of the E Programming Language

Abstract

E is an extension of C++ designed for writing software systems to support persistent applica- tions.Originally designed as a language for implementing database systems, E has evolved into a general persistent programming language E was the first C++ extension to support transparent persistence, the first C++ implementation to support generic classes, and remains the only C++ extension to provide general-purpose lterators, In addition to its contributions to the C + + programming domain, work on E has made several contributions to the field of persmtent languages in general, including several distinct implementations of persistence.Thm paper describes the main features of E and shows through examples how E addresses many of the problems that arise in building persistent systems.
