A Diy Approach to Uni-Temporal Database Implementation

2013 International Journal of Advanced Computer Science and Applications  
when historical versions of data are concerned for a MIS (Management Information System) we naturally might resort to temporal database products. These bi-temporal products, however, are often extravagant and not easily mastered to most of MIS practitioners. Hence we present a plain DIY (do it yourself) solution, the Audit & Change Logs Mechanism-based approach--ACLM, to meet the uni-temporal requirement from restoring historical versions of data. With ACLM programmers can code SQL scripts on

Besides, the ACLM approach is compatible with meta-data change, and its additive overhead was instantiated imperceptible for throughputs of routine access with a typical scenario. 123 | P a g e government MIS projects with requirements of uni-temporal database applications.
