摘要： A method and apparatus for performing file system operations involving a link is provided. A request to perform a file system operation involving a link is received from a client at a database server. The link may establish a relationship a source resource has to a target resource. The source resource and the target resource may be stored within a repository implemented by a storage medium, such as a database. The database server may perform the file system operation by storing, in the database, one or more link records that identifies the link between the first resource and the second resource. File system operations, such as a NFS file system operation, which involve links may be performed at a database management system.

摘要： Evaluation of workspace-local queries on a repository that supports versioning is enabled by tracking which versions of resources that are stored in the repository are associated with particular workspaces. A mapping is created and maintained for each workspace and each workspace-enabled table, i.e., a repository table that supports multiple versions of resources in the table. The mapping, such as a bit vector, is indexed by resource identifier. A set bit indicates that a particular resource version that corresponds to the bit is associated with the particular workspace. Therefore, the mapping indicates which rows in the workspace-enabled table are in the particular workspace. Index-based and functional evaluation schemes may utilize the per workspace, per table mapping to evaluate queries on the versioned repository. A new operator (IN_WORKSPACE) is introduced, through which an evaluation routine is invoked to determine whether or not a particular row maps to a particular workspace.

摘要： The present application allows wake-up and unlock operations to occur using a single event, such as a single keystroke. Additionally, a check is made to ensure that activation was caused by human touch, not an object. In one embodiment, an area of a mobile device is designated as a wake-up area, which is separate from the touch screen. A user can touch the wake-up area to both activate the mobile device from a sleep mode and unlock the mobile device. In another embodiment, the wake-up area can be integrated into the touch screen, so that there is not an appearance of a separate button. Fingerprint checking and/or proximity sensors can also be integrated into the mobile device.

摘要： A shared workspace is associated with a group of users who share the workspace, which isolates a set of shared resources from other resources stored in a repository that supports versioning of resources. The content of a shared workspace is maintained using a set of shared references, to the set of resources associated with the shared workspace. A virtual workspace is created for a user by generating a personal mapping for the user, where the personal mapping indicates which resources from the set of shared resources the user has made personal, e.g., by checking out such resources from the repository. If the user submits a query on the repository, the particular version of each resource involved in the query is readily determinable from the shared workspace and the user's virtual workspace.

摘要： The present invention relates to methods and systems of snapshot management of a file system in a data storage system. To represent the snapshots, the invention maintains pointers to the root block pointer of each snapshot. When the active file system is modified, this invention avoids overwriting any blocks used by previous snapshots by allocating new blocks for the modified blocks. When the invention needs to put an established block in a new location, it must update a parent block to point to the new location. The update to the parent block may then require allocating a new block for the new parent block and so forth. Parts of the file system not modified since a snapshot remain in place. The amount of space required to represent snapshots scales with the fraction of the file system that users modify. To maintain snapshot integrity, this invention keeps track of the first and last snapshots that use each block in space map blocks spread throughout the file system data space. When users delete snapshots, this invention may use a background process to find blocks no longer used by any snapshot and makes them available for future use.
摘要翻译：本发明涉及数据存储系统中文件系统的快照管理方法和系统。为了表示快照，本发明保持指向每个快照的根块指针的指针。当活动文件系统被修改时，本发明通过为修改的块分配新的块来避免覆盖先前快照所使用的任何块。当本发明需要将一个已建立的块放在新位置时，它必须更新一个父块以指向新的位置。然后，对父块的更新可能需要为新的父块等分配新块。文件系统的部分因为快照保留到位而未被修改。代表快照所需的空间量会随着用户修改的文件系统的一小部分而缩放。为了保持快照完整性，本发明记录使用遍及文件系统数据空间的空间图块中的每个块的第一个和最后一个快照。当用户删除快照时，本发明可以使用后台进程来查找不再被任何快照使用的块，并使之可供将来使用。

摘要： A database server stores compressed units in data blocks of a database. A table (or data from a plurality of rows thereof) is first compressed into a “compression unit” using any of a wide variety of compression techniques. The compression unit is then stored in one or more data block rows across one or more data blocks. As a result, a single data block row may comprise compressed data for a plurality of table rows, as encoded within the compression unit. Storage of compression units in data blocks maintains compatibility with existing data block-based databases, thus allowing the use of compression units in preexisting databases without modification to the underlying format of the database. The compression units may, for example, co-exist with uncompressed tables. Various techniques allow a database server to optimize access to data in the compression unit, so that the compression is virtually transparent to the user.
摘要翻译：数据库服务器将压缩单位存储在数据库的数据块中。使用各种各样的压缩技术中的任一种，首先将表（或其多行的数据）压缩为“压缩单位”。然后，压缩单元被存储在跨越一个或多个数据块的一个或多个数据块行。结果，单个数据块行可以包括在压缩单元内编码的多个表行的压缩数据。数据块中的压缩单元的存储与现有的基于数据块的数据库保持兼容，从而允许在预先存在的数据库中使用压缩单元，而无需修改数据库的底层格式。压缩单元可以例如与未压缩的表共存。各种技术允许数据库服务器优化对压缩单元中的数据的访问，使得压缩对于用户实际上是透明的。

摘要： For automatic data placement of database data, a plurality of access-tracking data is maintained. The plurality of access-tracking data respectively corresponds to a plurality of data rows that are managed by a database server. While the database server is executing normally, it is automatically determined whether a data row, which is stored in first one or more data blocks, has been recently accessed based on the access-tracking data that corresponds to that data row. After determining that the data row has been recently accessed, the data row is automatically moved from the first one or more data blocks to one or more hot data blocks that are designated for storing those data rows, from the plurality of data rows, that have been recently accessed.
摘要翻译：对于数据库数据的自动数据放置，维持多个访问跟踪数据。多个访问跟踪数据分别对应于由数据库服务器管理的多个数据行。当数据库服务器正常执行时，根据与该数据行相对应的访问跟踪数据，自动确定是否最近访问存储在第一个一个或多个数据块中的数据行。在确定最近访问了数据行之后，数据行被自动从第一个或多个数据块移动到指定用于存储来自多个数据行的那些数据行的一个或多个热数据块，这些数据行具有最近被访问。

摘要： A highly flexible and extensible structure is provided for physically storing tabular data. The structure, referred to as a compression unit, may be used to store tabular data that logically resides in any type of table-like structure. According to one embodiment, compression units are recursive. Thus, a compression unit may have a “parent” compression unit to which it belongs, and may have one or more “child” compression units that belong to it. In one embodiment, compression units include metadata that indicates how the tabular data is stored within them. The metadata for a compression unit may indicate, for example, whether the data is stored in row-major or column major-format the order of the columns within the compression unit (which may differ from the logical order of the columns dictated by the definition of their logical container), a compression technique for the compression unit, the child compression units (if any), etc.
