Performance analysis on data access patterns in layered Information Systems, an Architectural Perspective

Abstract

Layered architectures are the main architectures that are used in architecture of Information Systems. Data Access Layer (DAL) is a common layer in all layered architecture of Information Systems. One of the most important steps in architectural design of information systems is designing the DAL. More than 20 Data Access Patterns (DAP) have been developed for DALs. So providing a DAL based on existing DAPs is major activity in architectural design. Therefore an architect should be familiar to all existing DAPs and their evaluation parameters. Performance is one of most important parameter in architecture evaluation. In this paper, different aspects of performance of existing DAPs have been investigated and analyzed. To obtain this aim, firstly, a new classification has been provided for categorizing all DAPs based on architectures difference of them. Secondly, a simulation program as named DALSim has been developed for measuring performance of all DAPs. Finally, some comparisons of DAPs have been provided based on DALSim results. Based on provided classification for DAPs and performance comparison results of them, architects of information systems can easily compare and evaluate existing DAPs. With fully development of provided results in other aspect such as modifiability, extensibility, security etc., a complete framework for all DAPs can be provided.
