The separation of concerns principle is aimed at the ability to modularize separately those different parts of software that are relevant to a particular concept, goal, task or purpose. Appropriate separation of application concerns reduces software complexity, improves comprehensibility, and facilitates concerns reuse. Considering persistence as a common application concern, its separation from program's main code implies that applications can be developed without taking persistence requirements into consideration. As a result, persistence aspects may be plugged in at a later stage. This separation offers the developer handle persistence software attributes regardless the application functionality. We have analyzed different approaches to accomplish a complete separation of persistent features, appreciating that computational reflection achieves an entire transparency of persistence concerns, offering an enormous adaptability level. We present the implementation of a research-oriented prototype that illustrates how computational reflection can be used in future persistence systems to completely separate and adapt application persistence attributes at runtime.
Abstract. XML and XSLT apparently offer many advantages in Web site development. However after using them in several real projects we have found many disadvantages that results in a development process neither so productive nor easy. We propose a simple development process centered on reducing unnecessary interaction between programmers and graphic designers so they can focus on their fundamental tasks.
Persistence is a common application requirement that is usually taken into account when the program is being developed. Different emerging techniques following the Separation of Concerns principle are focused on detaching crosscutting concerns, like persistence, from the main application code. Although this is a profitable principle, existing tools lack two main features: runtime adaptability and language independence. This paper shows how computational reflection can be employed as a suitable technique to overcome the two previous limitations, offering dynamic adaptation of persistence features in a language independent way and achieving transparent separation of the application's persistence concern.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
