Aggregation is an important concept in database design where composite objects can be modelled during the design of database applications. Therefore, preserving the aggregation concept in database implementation is essential. In this paper, we propose models for implementation of aggregation in an Object-Relational Database Management System (ORDBMS) through the use of index clusters and nested tables. ORDBMS is a commercial Relational Database Management Systems (RDBMS), like Oracle, which support some object-oriented concepts. We will also show how queries can be performed on index clusters and nested tables.

What is risk aggregation?

AGGREGATION OF RISKS There has been much discussion of the RAROC and VaR methodologies as an approach to capture total risk management. Yet, frequently, the risk decision is separated from risk analysis. If aggregate risk is to be controlled, this or a similar methodology needs to be integrated more broadly and more deeply into the banking firm. Both aggregate risk methodologies presume that the time dimensions of all risks can be viewed as equivalent. A trading risk is similar to a credit risk, for example. This appears problematic when market prices are not readily available for some assets and the time dimensions of different risks are dissimilar. Yet, thus far no one firm has tried to address this issue adequately.


What does bleeding time reflect?

Bleeding time reflects the integrity of the vascular system and platelet function in the body. It measures how long it takes for bleeding to stop after a standardized skin puncture, indicating the efficiency of platelet adhesion, aggregation, and the function of the blood vessels. Prolonged bleeding time may suggest platelet disorders, vascular abnormalities, or the effects of certain medications. However, it is not a comprehensive test for all clotting disorders.


What is the difference between integrated and pooled?

Integrated typically refers to a system or approach where various components or elements work together cohesively, often sharing data and functionality to enhance efficiency and effectiveness. Pooled, on the other hand, suggests a gathering or accumulation of resources or data from multiple sources, often for collective use or analysis. While integration emphasizes synergy and collaboration, pooling focuses on the aggregation of resources or assets.
