Containment of Relational Queries with Annotation Propagation
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
Despite this, we show that the same annotated result is obtained whether intermediate constructs of a query are evaluated with set or bag semantics. ...
We say that a query is annotation-contained in another if the annotated output of the former is contained in the latter on every possible annotated input databases. ...
Semantics of Queries with Annotations. Intuitively, annotations are propagated from an input database to the result of a query according to the bindings of variables. ...

In this system, every piece of data in a relation is assumed to have zero or more annotations associated with it and annotations are propagated along, from the source to the output, as data is being transformed ...
For the default-all scheme, we also show how we generate finitely many queries that can simulate the annotation propagation behavior of the set of all equivalent queries, which is possibly infinite. ...
Acknowledgements We thank Xinyu Hua for her help during the initial implementation of this system and Ariel Fuxman for helpful suggestions. ...

We then look at how queries can be applied to such hierarchies; in particular we ask the usual question of how annotations should propagate through queries. ...

We study two classes of view update problems in relational databases. We are given a source database S, a monotone query Q, and the view Q(S) generated by the query. ...
On the other hand, suppose we annotate an attribute of a tuple in the view Q(S), what annotation(s) in S will cause this annotation to appear in the view, minimizing the propagation to other attributes ...
Thus the propagation of this annotation has nothing to do with the query that produced this tuple. ...

Compared to storing the annotations with the individual cells, the proposed schemes achieve more than an order-of-magnitude reduction in storage and up to 70% saving in the query execution time. ...
These annotation types raise several storage and processing challenges that are addressed in the paper. We propose declarative ways to add, archive, query, and propagate annotations. ...
The ON AGGREGATION PROP-AGATE clause specifies that at the time of querying the data, if the user query contains aggregation, e.g., GROUP BY or DISTINCT, then keep propagating the annotation along with ...
