Abstract: Cross tenant data access is provided by creating a logic view in a meta database with respect to at least a first tenant of a group of tenants and according to metadata about the respective tenants. The logic view is based upon first data owned by the first tenant as well as second data that is owned and authorized by at least another tenant of the group of tenants for the first tenant to access. The logic view in the meta database is accessed in response to a cross tenant data access request from an application of the first tenant.

Abstract: A brake/clutch device for a manual hoist provides an externally-viewable indicator showing the wear status of friction elements within the hoist. The brake/clutch device has a brake block, a brake ratchet, a reversing ratchet, a torsion spring block, a hand wheel and a fastener mounted onto a main shaft of the manual hoist. Friction elements on the brake ratchet provide braking against sudden drops of a load. Ball and spring devices mounted in the hand wheel contact detents and grooves that gradually increase in depth in the torsion spring block depending on the relative positions of the hand wheel and the torsion spring block. The hand wheel has an indicator mark that may align with indicator areas of the torsion spring block to indicate an extent of wear of the friction elements.

Abstract: A method and system for placing database. The method includes: receiving a request of creating a new database; determining whether there is a need to migrate current database among current virtual machines based on resource demand and free resource in the current virtual machines; determining database placement plan based on the resource demand, migration strategy and migration cost associated with the migration strategy in response to whether there is a need to migrate the database; and executing the database placement plan. The invention can help a database service provider to optimize database layout in database provision through database migration.

Abstract: Embodiments relate to manipulating a multi-tenant database, wherein the multi-tenant database comprises one or more source databases for storing tenant data. An aspect includes receiving a database operation request for one or more tenant-specific logic views, wherein the tenant-specific logic views are created for respective tenants based on mapping information pointing to the one or more source databases included in the multi-tenant database and multi-tenant metadata. Another aspect includes acquiring the mapping information related to the database operation request and pointing to the one or more source databases included in the multi-tenant database. Yet another aspect includes performing a database operation corresponding to the database operation requested for the one or more source databases based on the acquired mapping information.

Abstract: This invention publishes a kind of fan blade which can be assembled and disassembled quickly, including blade and blade bracket for ceiling fan, desk fan, pole fan, etc. In this invention, the blade and blade bracket are joined together by the inserting structure. During assembling, we only need to align the mounting holes with the elastic connectors and press downwards forcibly, and then the blade could be installed on the blade bracket securely. In this invention, screws are unnecessary for installing the blade on the blade bracket. The assembling is fast and the inserting structure is firm and reliable. When it comes to the necessity of disassembling the blade, only a press plate with matched holes is needed to press the elastic connectors and separate the blade from the blade bracket, which could greatly enhance the ease of use.
