Abstract: A system, method and computer program product for enabling light weight table comparison with high-accuracy (high confidence) of tables where one is a copy of the other, which copy may be maintained synchronized by replication. The method performs database comparison using a sample-based, statistics-based, or materialized query tables-based approaches. The method first identifies a block comprising a sub-set of rows of data of a source database table and a corresponding block from a target database table, and obtains a statistical value associated with each block. Then the statistical values for the corresponding source and target block are compared and a consistency evaluation of source and target database is determined based on comparing results. Further methods enable a determination of the data as being persistent or not in manner that accounts for real-time data modifications to underlying source and target database tables while identified blocks are being compared.

Abstract: An exemplary computer case includes an external shell, a circuit board received in the external shell, and a dehumidification device. The circuit board includes a PCI socket providing an auxiliary power supply when the computer shuts down but the computer case retains electrical connection with an external AC power source. The dehumidification device includes a dehumidification card received in the PCI socket for obtaining the auxiliary power supply therefrom and a remote device. The dehumidification card includes a fan for generating airflow to remove moisture from the computer case and a sensor detecting a humidity inside the computer case. The remote device includes a display unit for displaying the result. When the humidity exceeds a predetermined value, the computer is not powered up until the fan evacuates the excess moisture from the computer case and the humidity falls below the predetermined value.

Abstract: A slide rail includes an outer rail, an intermediate rail slidably received in the outer rail, a first inner rail slidably received in the intermediate rail opposite to the outer rail, a second inner rail slidably received in the intermediate rail opposite to the outer rail, a protuberance disposed on the first inner rail, a latch member connected to the second inner rail, and a releasing member connected to the outer rail. The first and second inner rails are arranged adjacent to opposite first and second ends of the outer rail. The latch member is capable of engaging with or disengaging from the protuberance. When the first inner rail slides out of the outer rail from the first end, the releasing member is configured to abut against the latch member and urge the latch member to disengage from the protuberance.
