Abstract: A system, method, and computer program product are provided for repartitioning data based on access of the data. In use, an addition of a new partition in memory to at least one existing partition in the memory across which data is stored is detected. Additionally, access to a portion of the data is identified. Further, one of the at least one existing partition in the memory in which the portion of the data is stored is determined. Moreover, the portion of the data is repartitioned from the one of the at least one existing partition to the new partition while allowing access to other portions of the data, in response to the identification of the access to the portion of the data.

Abstract: A method for providing personalized advertisement to a first user. The method includes the steps of: displaying a first advertisement to users; defining segments for a user community preference; assigning each of the users to one of the segments in response to the user's level of interest in the user community preference; identifying a first group of the users interested in the first advertisement; identifying a second group of the users not interested in the first advertisement; determining the percentage of the first group of users assigned to the segment; determining the percentage of the second group of users assigned to the segment; determining whether each segment is an indicator for user interest in the first advertisement by comparing the two percentages associated with the segment; and targeting a second advertisement to users assigned to the segment if the segment is an indicator for user interest in the first advertisement.
