| Abstract(in English) | Recently, very large databases have commonly been used to manage large volumes of electronic data. As a result, the storage cost is increasing. To cut down the storage cost, we have proposed a database compression mechanism using knowledge discovery techniques. However, so far we have not considered the indexing mechanism for compressed databases, which plays an important role especially in large databases. In this paper, we show two indexing mechanisms, i.e., the divided indexing and the virtual indexing, for databases compressed with knowledge discovery techniques. The divided indexing mechanism adds an index to each fragmented table, while the virtual indexing mechanism adds a single index to the fragmented tables as if they were a single table. We also give evaluation of these two indexing mechanisms. |
