Abstract
Methods, systems, and computer program products for database table aggregation are provided. A method includes encoding first and second components via a waveform definition, the first and second components specifying first and second criteria, respectively, for aggregating data. The method includes generating a complex periodic aggregation waveform (CPAW) having variable-sized square waves representing the components in a repeating pattern corresponding to the definition and the criteria, and which spans a first axis. The method includes providing a maximum byte count for aggregated data stored in a table defined by the first and/or second criteria, aggregating the data in accordance with the criteria, and creating a new table for overflow of data determined for the table when the maximum byte count is exceeded. The method includes updating the CPAW with results of the aggregation and generating a waveform representing the new table along a second axis.
