Abstract: A query analyzer may be used to identify a plurality of queries and associated query characteristics, the query characteristics including a corresponding dataset of data units for each query, wherein the data units are to be loaded from an offline memory into a memory of an in-memory database. Then, a sequencer may be used to select a selected dataset for loading into the memory of the in-memory database, based on dependencies between the plurality of queries as included within the query characteristics, and on relationships, if any, between the datasets.

Abstract: An inkjet print head chip. The chip has a first column of firing chambers and a second column of firing chambers in which each firing chamber comprises a heater and an ink channel. A first ink slot is formed between the first column of firing chambers and the periphery of the chip, in which the first ink slot comprises a plurality of first ink sub-slots and each first ink sub-slot provides ink to part of heaters in the first column of firing chambers. A second ink slot is formed between the second column of firing chambers and the periphery of the chip to provide ink to the heaters in the second column of firing chambers. A dry film is patterned on the entire surface of the chip to separate the first ink sub-slots.
