In this work we describe a high-performance stream-oriented distributed database manager and query processor under development that allows efficient execution of database queries to streamed data involving numerical and other data. Very high performance is attained by utilizing many object-relational main-memory database engines running on PCs and connected through the GRID.

Data sanitization is a process that is used to promote the sharing of transactional databases among organizations and businesses, it alleviates concerns for individuals and organizations regarding the disclosure of sensitive patterns. It transforms the source database into a released database so that counterparts cannot discover the sensitive patterns and so data confidentiality is preserved ag...

Real-time main-memory databases are useful in real-time environments. They are often faster and provide more predictable execution of transactions than disk-based databases do. The most reprehensible feature is the volatility of the memory. In the RODAIN Database Architecture we solve this problem by maintaining a remote copy of the database in a stand-by node. We use logs to update the databas...

We describe the model and implementation of two approaches for method execution in distributed object query processing. The first approach is the traditional data migration approach in which remote data accesses (if required) are made to compose an in-memory object at the query site which is followed by method invocation on this object. The second approach of method migration allows the method ...
