摘要： A method, apparatus, and system for automatically determining an optimal database subsection is provided. A database subsection is selected to optimize certain benefits when the database subsection is translated, transferred, and cached on an alternative database system, which may utilize a different technology or database engine that provides certain performance benefits compared to the original database system. Algorithms such as multi-path greedy selection and/or dynamic programming may provide optimal or near-optimal results. A host for the alternative database server may be shared with or otherwise located in close physical proximity to improve latency for a database application or client layer. Once the database subsection analysis is completed, a report may be generated and presented to the user, and an implementation script may also be created to automatically configure a client host to function as a cache or replacement system according various cache size configurations described in the report.

摘要： A method maintaining an image background by multiple Gaussian models utilized to a device includes the following steps. First, the device captures an image frame having pixels to obtain background information, and then calculates the background information to establish a primary Gaussian model. Next, the device captures continuous image frames in a time period to obtain and calculate graphic information for establishing a secondary Gaussian model, and then repeates the steps to establish multiple secondary Gaussian models. Finally, the device compares two secondary Gaussian models, and then updates learning for the primary Gaussian model by the secondary Gaussian model if the graphic information of the secondary Gaussian models are attributable to the background information, or maintains the background information of the primary Gaussian model without updating the learning if anyone of the graphic information of the two secondary Gaussian models is unattributable to the background information.
摘要翻译：通过用于设备的多个高斯模型来保持图像背景的方法包括以下步骤。首先，设备捕获具有像素的图像帧以获得背景信息，然后计算背景信息以建立主高斯模型。接下来，设备在一段时间内捕获连续的图像帧以获得和计算用于建立次高斯模型的图形信息，然后重复建立多个次高斯模型的步骤。最后，设备比较两个二次高斯模型，然后如果二次高斯模型的图形信息可归因于背景信息，则可以通过二次高斯模型更新主高斯模型的学习，或维持主高斯模型的背景信息如果任何两个二次高斯模型的图形信息不符合背景信息，则不更新学习。

摘要： A system includes an active node and a standby node and zero or more replica nodes. Each of the nodes includes a database system, such as an in-memory database system. Client updates applied to the active node are written through to the standby node, and the standby node writes the updates through to a primary database and updates the replica nodes. Commit ticket numbers tag entries in transaction logs and are used to facilitate recovery if either of the active node or the standby node fails. Updates applied to the primary database are autorefreshed to the active node and written through by the active node to the standby node which propagates the updates to the replica nodes. Bookmarks are used to track updated records of the primary database and are used to facilitate recovery if either of the active node or the standby node fails.

摘要： In column domain dictionary compression, column values in one or more columns are tokenized by a single dictionary. The domain of the dictionary is the entire set of columns. A dictionary may not only map a token to a tokenized value, but also to a count (“token count”) of the number of occurrences of the token and corresponding tokenized value in the dictionary's domain. Such information may be used to compute queries on the base table.

摘要： A replication track is a designated group of transactions that are to be replicated at a destination database in a way that, with respect to any other transaction in the replication track, preserves transactional dependency. Further, transactions in a replication track can be replicated at the destination database without regard to transactional dependency of other transactions in another track. This facilitates concurrent parallel replication of transactions of different tracks. Replicating data in this manner is referred to herein as track replication. An application may request execution of transactions and designate different tracks for transactions.

摘要： A plurality of mid-tier databases form a single, consistent cache grid for data in a one or more backend data sources, such as a database system. The mid-tier databases may be standard relational databases. Cache agents at each mid-tier database swap in data from the backend database as needed. Consistency in the cache grid is maintained by ownership locks. Cache agents prevent database operations that will modify cached data in a mid-tier database unless and until ownership of the cached data can be acquired for the mid-tier database. Cache groups define what backend data may be cached, as well as a general structure in which the backend data is to be cached. Metadata for cache groups is shared to ensure that data is cached in the same form throughout the entire grid. Ownership of cached data can then be tracked through a mapping of cached instances of data to particular mid-tier databases.

摘要： The improvement of the pedestal of roller shoes, which is a technique in the field of sports shoes, provides the capability of shock absorption. The improvement of the pedestal includes the following features: the middle part of the joint shelf is mounted to the pedestal, a roller is mounted to the one end; the middle part of the spring steel plate is mounted to the appropriate place of the pedestal, the two ends of it mount to the other ends of the two joint shelves. This new design will absorb the shock imposed on the rollers via the damping of the spring steel plate, and prevent the shock from going to the feet of the user.
