摘要： The subject innovation provides a system and/or a method that facilitates developing schemas for a file storage system. A type definition component can provide a schema grammar, wherein a generator component can employ the schema grammar to build the schema for the file storage system. The schema grammar can describe information types stored in the file storage system that are represented as instances of complex types that are part of a type system that supports inheritance. The schema grammar can support a declaration of an association between types, versioning specifications, and/or content indexing specifications.

摘要： The subject invention provides a system and/or a method that facilitates mapping a data base model to a database object. A type storage system can utilize a storage mapping of a file storage data model. The mapping can describe the database object created based at least in part upon a schema and how instances of the type described in the schema are stored and/or accessed. Furthermore, a query can be provided to find at least one of an item, a document, and/or a contact that satisfy at least one criterion. The type storage system can receive data, wherein the data is at least one of a schema, a data model, a type, a query, and query criteria via an interface to provide the storing and querying. Additionally, the type storage system can generate a view that exposes at least one instance of the type.

摘要： The present invention is directed a logical consistency checker (LCC) working alone or in conjunction with a physical consistency checker (PCC) and/or a data reliability system (DRS) for a database files system of a hardware/software interface system. Logical data correction pertains to logical data corruptions for entities (e.g., items, extensions, and/or relationships in an item-based operating system, where an item-based operating system is one example of an item-based hardware/software interface system). In this regard, a LCC analyses and corrects logical damage to entities representatively stored in the data store in order to ensure that all such entities in said data store are both consistent and conform to the data model rules.

摘要： A system for automatic statistics creation comprises a query optimizer which automatically generates statistics derived from data in a database and selects an executable procedure from a plurality of procedures that operate on data in a database using the automatically generated statistics. A counter is maintained of updates made to each statistic that has been automatically generated. If the counter breaches a threshold, the automatically generated statistic is removed from the database.

摘要： A system and method allowing for optimization of query execution in database environments is provided. In an illustrative implementation, a database having distributed partitioned views is provided such that queries may initiate at any of the participating data stores. In operation, an offered query is analyzed to determine if it has predicate expression and/or sub-queries. Using this information the expressions and/or sub-queries are analyzed and processed to determine if appropriate start-up filters are available for the offered query. The start-up filters are applied to the query such that during compile and/or run time, redundant partitions in the distributed partitioned database environment are eliminated during query execution.

摘要： Architecture that eliminates the need for on-disk full backups of data retaining only changes that have occurred, in a separate table. Thus, the architecture provides for incremental recovery of incremental changes in a relational database (e.g., SQL). The architecture provides improved recovery time and recovery point objectives. By using the incremental capture of changed data (e.g., in an XML format), the capability is provided to capture schema changes, query the incremental change data and efficiently restore user data to an earlier point-in-time state. Changes (e.g., insert, update and delete operations) are tracked (e.g., continuously) by a set of triggers and the incrementally captured changed rows are inserted in a data capture table (a differential change “delta” table) in a human-readable format (e.g., XML). Rollback is also provided.

摘要： A compressed trie has nodes including multiple character sub-strings. Such multiple character storage reduces the number of nodes in the trie, thereby reducing the amount of memory required for storing the trie and reducing the amount of time required to perform matching. Furthermore, in such a compressed trie, sub-strings are stored in a single character string. Each node references its corresponding sub-string by the sub-string's starting position and length in the character string. Multiple nodes may reference a single sub-string. Thus, referencing rather than storing sub-strings in corresponding nodes eliminates repetitive sub-string storage, thereby reducing the amount of memory required for storing the trie.
摘要翻译：压缩特技包含多个字符子串的节点。这种多字符存储减少了特里部分中的节点数量，从而减少了存储所需的内存所需的内存量，并减少了执行匹配所需的时间量。此外，在这样的压缩特技中，子串被存储在单个字符串中。每个节点通过子字符串的起始位置和字符串中的长度引用其对应的子字符串。多个节点可以引用单个子串。因此，引用而不是将子串存储在相应的节点中消除了重复的子串存储，从而减少了存储该线索所需的内存量。

摘要： The subject invention provides a system and/or a method that facilitates providing a compact representation of a file path associated to a file storage system. A path component can provide seamless integration and/or transition between the file path associated to the file storage system and an item and/or item ID within the data storage system. The path component can utilize a tabular format, wherein such tabular format allows the cross-reference between the file path and item. The compact representation can facilitate at least one of storing, renaming, and searching.

摘要： A system for automatically maintaining database statistics comprises a query optimizer which automatically generates statistics derived from data in a database and selects an executable procedure from a plurality of procedures that operate on data in the database using the automatically generated statistics. The query optimizer maintains counters of changes made to the data and automatically updates statistics derived from the data when the counters exceed a threshold. A statistic schema version is maintained for each statistic and incremented when the underlying data is updated. If the statistic schema version changes from that value with which the execution plan was generated, the execution plan is discarded and a new execution plan developed.

摘要： A framework for data change notification includes a notification queue storing event notifications. Client applications can request event information regarding various data change events. For example, a client application can subscribe, via one or more APIs, to receive event information. The framework allows for session specific event notification mechanisms as well as durable event notification mechanisms that can be preserved across client sessions as well as server restarts. Innovative aspects of this invention include guaranteed delivery of event notifications, APIs to allow applications get summary of past events on the subscribed objects, automatic garbage collection/cleanup of notifications when a client session terminates.
