This paper presents a query processing algorithm called DE CAF for use in middleware object query systems that are based on the use of an object cache. The DECAF algorithm is designed to work correctly even in the presence of updates to the underlying databases that don't go through the object cache (i.e., even for autonomous data sources that can be updated through legacy applications that do not perform their updates through the middleware object layer). DE CAF's query results are consistent with updates performed by such transactions;its results are also consistent with any deferred updates that are present in the object cache but not yet committed at the database server. The DECAF algorithm attempts to push down query predicates to the underlying DBMSs to take advantage of the query processing capabilities of these systems and to reduce the amount of data, transferred from these systems to the object cache.

It is essential for security to be able to isolate mistrusting programs from one another, and to protect the host platform from programs. Isolation is difficult in object-orientedsystems because objects can easily become aliased. Aliases that cross program boundaries can allow programs to exchange information without using a system provided interface that could control information exchange. In Java, mistrusting programs are placed in distinct loader spaces but uncontrolled sharing of system classes can still lead to aliases between programs. This paper presents the object spaces protection model for an object-oriented system. The model decomposes an application into a set of spaces, and each object is assigned to one space. All method calls between objects in different spaces are mediated by a security policy. An implementation of the model in Java is presented.
