20080229664 | Two Piece Carrier and Balance Assembly - A carrier and balance assembly for installation into the jamb channel of a window frame. The carrier and balance assembly are capable of being installed into the jamb channel optionally either as a single assembly or as two separate components. The two separate components are the carrier and a hanger-balance subassembly. The advantage of installing the carrier and balance assembly as two separate components is that such installation can occur after the assembly of the window frame and even after installation of the window into the wall of a building. Once the carrier and hanger-balance subassembly are separately installed in the jamb channel, they are then non-permanently locked together. Should any part of the carrier and balance assembly become damaged, replacement is performed by simply reversing the process described above without having to damage the jamb channel. | 09-25-2008 |

20140214796 | EFFICIENT JOIN WITH ONE OR MORE LARGE DIMENSION TABLES - Embodiments of the invention relate to processing queries that utilize fact and/or dimension tables. In one aspect, a pre-join filtering phase precedes a star join. The necessary conditions for the pre-join filtering are considered for a given SQL query, including an estimated size of the hash table exceeding a threshold and presence of a local predicate either on the fact table or one or more dimension tables that is not a large dimension table. Once the necessary conditions are satisfied, the execution of the query exploits the pre-join filtering to build a pre-join output filter from columns of a reduced fact table that joins with each large dimension table. Thereafter, all the dimension tables and the fact table are joined in a star join while exploiting each pre-join filter. Accordingly, the order of when joins occur is changed in order to reduce the size of the fact table and to work from the fact table to reduce the size of large dimension tables. | 07-31-2014 |
