A BI system can now answer questions that the developers did not have the need to know in advance that the question was going to be asked. BI systems are made possible by organizing the data in a form called Hypercube. This form explores the many dimensions of the data, and allows...

Column-oriented databases are better suited to OLAP scenarios. They are at least100x fasterin processing most queries. ClickHouse uses all available system resources to their full potential to process each analytical query as fast as possible. ...
Full size image What is a low or high processing intensity, and consequently, the slowdown of accessing sequential inputs from storage relative to memory is a function of storage bandwidth. Figure2models the execution time of increasingly processing-intensive queries normalized to the in-memory execu...
Full size image 3.2 Data Indexing To support efficient bus non-on-time queries, we implement an index based on attribute domain partition in Bus-OLAP. Specifically, we divide the domain of each attribute into several disjoint partitions. Then, for each attribute value of a record, we build a...
make matters worse, if dimensions were added, the underlying fact table was updated or the cube was built using different aggregations, there was no way to determine the full effects of these changes. A seemingly innocent change could have a far-reaching and cascading effect...
