Adaptive Change Management for Semi-structured Data

چکیده
This paper presents an efficient content-based version management system for managing XML documents. Our proposed system uses complete deltas for the logical representation of document versions. This logical representation is coupled with an efficient storage policy for version retrieval and insertion. Our storage policy includes the conditional storage of complete document versions (depending on the proportion of the document that was changed). Based on the performance measure from experiments, adaptive scheme based on non-linear regression is proposed. Furthermore, we define a mapping between forwards and backwards deltas in order to improve the performance of the system, in terms of both space and time.
