Collaborative caching for distributed mobile database query processing by Elfaki, Mohamed Ahmed, Ibrahim, Hamidah, Mamat, Ali, Othman, Mohamed

“…Since our approach deals with continuous query, we propose a framework for improving the process of continuous query mechanism that caches and shares the query’s result among the nodes within the same cluster or with external database (neighbors cluster or main data server).…”

An efficient approach for processing skyline queries in incomplete multidimensional database by Alwan, Ali Amer, Ibrahim, Hamidah, Udzir, Nur Izura, Sidi, Fatima

“…In this paper, we proposed an efficient approach for processing skyline queries in incomplete database. The experimental results show that our proposed approach has significantly reduced the number of pairwise comparisons and the processing time in determining the skylines compared to the previous approaches.…”

Dominance relationship-based skyline query framework over dynamic and incomplete database by Dehaki, Ghazaleh Babanejad

“…However, computing the skylines over the entire database after changes are made is inefficient as not all the data items are affected by the changes. In tackling the above stated issues, we propose a solution, named DyIn-Skyline, which consists of three main phases, namely: Phase I – processing skyline queries over the initial incomplete database, Phase II – processing skyline queries over a dynamic and incomplete database, in which the changing state of the database is due to a data manipulation operation(s) (insert, delete or update a data item(s)), and Phase III – processing skyline queries over a dynamic and incomplete database, in which the changing state of the database is due to a data definition operation(s) (add or remove a dimension(s)). …”
