Abstract
Cached materialized view has lots of benefits, but it has inconsistency problem when the data source is modified. This paper proposes an incremental maintenance algorithm IMA to implement incremental maintenance of materialized XPath view. The characteristics of IMA are: (1) It can establish an incremental maintenance program automatically; (2) The incremental maintenance program is simple and its function is reassembling the materialized XPath view to obtain a consistent view; (3) The incremental maintenance program is written in XQuery language and can be executed by any XQuery engine; (4) The only auxiliary data used to maintain the materialized XPath view is the incremental maintenance program and its size cost is very small. Experiments have shown that this approach outperforms view recomputation.
