Aggregate Queries Over Conditional Tables | SpringerLink

Conditional tables have been identified long ago as a way to capture unknown or incomplete information. However, queries over conditional tables have never been allowed to involve column functions such as aggregates. In this paper, the theory of conditional tables is extended in this direction, and it is shown that a strong representation system exists which has the closure property that the ...

Aggregate (data warehouse) - Wikipedia

Having aggregate data in the dimensional model makes the environment more complex. To make this extra complexity transparent to the user, functionality known as aggregate navigation is used to query the dimensional and fact tables with the correct grain level. The aggregate navigation essentially examines the query to see if it can be answered ...

SQL Server MAX() aggregate function

The SQL MAX() aggregate function can be also used within the WHERE clause of a simple SELECT query. This can be achieved by comparing a specific column value with the result returned from a subquery that returned the maximum value of that column, as shown in the T-SQL SELECT query below:

Automated Assessment of Aggregate Query Imprecision for ...

We introduce a model for aggregate queries that applies an in-network aggregation operator and returns a bounded aggregate value as a result. These bounds convey the degree to which the provided query result reflects the ground truth (i.e., the state of the environment during query execution). The bounded aggregate is simply a triple: [L,A,U ...

We introduce a first-order language with real polynomial arithmetic and aggregation operators (count, iterated sum and multiply), which is well suited for the definition of aggregate queries involving complex statistical functions. It offers a good trade-off between expressive power and complexity, with a tractable data complexity. Interestingly, some fundamental properties of first-order with ...
