Tytuł:: Time complexity of page filling algorithms in Materialized Aggregate List (MAL) and MAL/TRIGG materialization cost
Autorzy:: Gorawski, M.
Powiązania:: https://bibliotekanauki.pl/articles/970792.pdf
Data publikacji:: 2009
Wydawca:: Polska Akademia Nauk. Instytut Badań Systemowych PAN
Tematy:: spatial data warehouse

indexing
materialized aggregate list
time complexity of MAL algorithms
Opis:: The Materialized Aggregate List (MAL) enables effective storing and processing of long aggregates lists. The MAL structure contains an iterator table divided into pages that stores adequate number of aggregates. Time complexity of three algorithms was calculated and, in comparison with experimental results, the best configuration of MAL parameters (number of pages, single page size and number of database connections) was estimated. MAL can be also applied to every aggregation level in different indexing structures, like for instance the aR-tree.
