According to one embodiment of the present invention, a system compares database transactions to corresponding performance information to identify conforming database transactions with an acceptable deviation from the performance information and outlier database transactions beyond the acceptable deviation from the performance information. The system aggregates information from a threshold quantity of conforming database transactions into an aggregated record, wherein the threshold quantity is dynamically adjusted, and generates a record for each outlier database transaction, wherein conditions for identifying the outlier database transactions are dynamically adjusted. Embodiments of the present invention further include a method and computer program product for managing database transactions in substantially the same manners described above.
