An object-oriented language-database integration model: The composition-filters approach

Abstract

This paper introduces a new model, based on so-called object-composition filters, that uniformly integrates database-like features into an object-oriented language. The focus is on providing persistent dynamic data structures, data sharing, transactions, multiple views and associative access, integrated with the object-oriented paradigm. The main contribution is that the database-like features are part of this new object-oriented model, and therefore, are uniformly integrated with object-oriented features such as data abstraction, encapsulation, message passing and inheritance. This approach eliminates the problems associated with existing systems such as lack of reusability and extensibility for database operations, the violation of encapsulation, the need to define specific types such as sets, and the incapability to support multiple views. The model is illustrated through the object-oriented language Sina.

“…3 The name instanceof is chosen because of the similarity in semantics to Java's instanceof operator. 4 This will match calls that come from static methods. Since there is no currently executing object in such methods, instanceof(FigureElement) will not match such join points.…”

Managing software complexity of adaptive systems

“…A key design goal of the Composition Filters model is to improve the composability of programs written in object-based programming languages. The Composition Filters model has evolved from the first (published) version of the Sina language in the late 1980s [10,11], to a version that supports language independent composition of crosscutting concerns [19,101].…”
