We provide here two restricted calculi with bounded complexity, and show that the restrictions are minimal. Indeed, any looser restriction leads to non computable queries.

The algebra addresses issues of type-defined equality and duplicate elimination as well as extensions to bulk types other than sets.

Nested Queries in Object Baseshe query language level in order to treat common subexpressions and independent subqueries more efficiently. The transformed queries are translated to nested algebraic expressions. These entail nested loop evaluation which may be very inefficient. Hence, the second phase . nested algebraic expressions to allow for more efficient evaluation.

How Dogmatic Can Materialism Be?n capabilities. It is shown how the module structure provides explicit support for sharing and simplifies the development of reusable components. The capability structure allows control over access to data and supports deletion of objects in a controlled manner.

How Dogmatic Can Materialism Be?ific data, etc. require database support for ordered data structures like lists, trees, and graphs. In this paper, we discuss an extension to the AQUA query algebra to handle ordered types and their operators. We show how these operators can fit into a framework for query optimization.
