This book focuses on the distance-based range queries that continuously changes their locations in an Euclidean space. An efficient and effective monitoring technique is presented based on the concept of a safe zone. The safe zone of a query is the area with a property that while the query remains inside it, the results of the query remain unchanged. Hence, the query does not need to be reevaluated unless it leaves the safe zone. The contributions are as follows: 1) The technique based on powerful pruning rules and a unique access order is presented, which efficiently computes the safe zone...

Preparing a data set for analysis is generally the most time-consuming task in a data mining project, requiring many complex SQL queries, joining tables, and aggregating columns. In general, a significant manual effort is required to build data sets, where a horizontal layout is required. Here introduces simple, yet powerful, methods to generate SQL code to return aggregated columns in a horizontal tabular layout, returning a set of numbers instead of one number per row. This new class of functions is called horizontal aggregations. An aggregation function with a grouping technique gives...
