摘要： A method and system for increasing server cluster availability by requiring at a minimum only one node and a quorum replica set of replica members to form and operate a cluster. Replica members maintain cluster operational data. A cluster operates when one node possesses a majority of replica members, which ensures that any new or surviving cluster includes consistent cluster operational data via at least one replica member from the immediately prior cluster. Arbitration provides exclusive ownership by one node of the replica members, including at cluster formation, and when the owning node fails. Arbitration uses a fast mutual exclusion algorithm and a reservation mechanism to challenge for and defend the exclusive reservation of each member. A quorum replica set algorithm brings members online and offline with data consistency, including updating unreconciled replica members, and ensures consistent read and update operations.
摘要翻译：通过至少要求一个节点和副本成员的仲裁复制集来形成和操作集群，来提高服务器集群可用性的方法和系统。副本成员维护集群操作数据。当一个节点拥有大多数副本成员时，集群就会运行，从而确保任何新的或存活的集群通过至少一个来自紧接在前的集群的副本成员包括一致的集群操作数据。仲裁提供复制成员的一个节点的独占所有权，包括在集群形成时以及所有节点出现故障时。仲裁使用快速互斥算法和保留机制来挑战和保护每个成员的独家保留。仲裁复制集算法使成员在线和离线具有数据一致性，包括更新未协调的副本成员，并确保一致的读取和更新操作。

摘要： Aspects of the subject matter described herein relate to automating evolution of schemas and mappings. In aspects, mappings between a conceptual model and a store model are updated automatically in response to a change that occurs to the conceptual model. For example, when a change occurs to the conceptual model, a local scope of the change is determined. The local scope indicates mappings that are most similar to the type(s) affected by the change. Based on the local scope, a pattern of mappings between the conceptual model and the store model is determined. Using this pattern and the nature of the change, the mappings are updated according to the pattern. In addition, the store model and data thereon may be updated in a manner to preserve existing data that is not to be deleted in response to the change.

摘要： A data structure may exist in various representations, such as an object in an object-oriented system or a set of elements included in an extensible markup language (XML) document structured according to an XML type defined in an XML schema. While many aspects of these representations may correspond, some aspects of an XML document may not be specified by the XML schema (such as developer comments, whitespace, and preprocessor directives), and may be lost while translating an XML representation of the data structure to an object. These non-schematized aspects may be included in the object as a delta, specifying the location of an aspect with relation to an element defined by the XML schema. Preserving non-schematized aspects may promote the full representation of the data structure as an object, and may facilitate a full-fidelity regeneration of the XML document from which the object was generated.
摘要翻译：数据结构可以存在于各种表示中，例如面向对象系统中的对象或根据在XML模式中定义的XML类型而构造的可扩展标记语言（XML）文档中的一组元素。虽然这些表示的许多方面可能对应，XML文档的某些方面可能不被XML模式（例如开发人员注释，空白和预处理指令）指定，并且可能在将数据结构的XML表示转换为一个东西。这些未示意的方面可以作为增量包含在对象中，指定与由XML模式定义的元素相关的方面的位置。保留非示意性方面可以促进数据结构作为对象的完全表示，并且可以促进对象被生成的XML文档的完全保真再生。

摘要： Prefetching and caching persistent objects is disclosed. The system creates a structure context used to identify a set containing a first object and other related objects. The objects have attributes, where each attribute is identified by a name. Upon a fetch of an attribute in the first object, the system also fetches related data. The related data includes other attributes in the object, and attributes in the other objects of the set having the same name as the attribute fetched for the first object.

摘要： A general-purpose reusable algebraic-based composition algorithm for composing mappings between data schemas. The algorithm handles more expressive mappings, makes a best-effort to eliminate symbols when a perfect answer cannot be obtained, includes new heuristics, and is extensible. A relational algebraic language is provided wherein each mapping is expressed as a set of constraints, and each constraint is either a containment or equality of two or more relational algebraic expressions. The composition mechanism exploits monotonicity properties of algebraic operators in operator arguments, handles NULLs and bag semantics, operates to allow composition to produce a partial result when a complete result is not possible, facilitates symbols elimination one symbol at a time using left composition, for example, as a way of isolating the symbols, supports making a best-effort to eliminate as many symbols as possible from an intermediate schema, and handles unknown or partially known operators via delayed handling.
摘要翻译：一种用于组合数据模式之间映射的通用可重用代数组合算法。该算法处理更具表现力的映射，尽最大努力在无法获得完美答案时消除符号，包括新的启发式，并且是可扩展的。提供了关系代数语言，其中每个映射被表示为一组约束，并且每个约束是两个或多个关系代数表达式的容纳或相等。组合机制利用代数运算符在运算符参数中的单调性，处理NULL和包语义，运算以允许组合在不完整结果时产生部分结果，便于使用左组合一次使用符号消除一个符号作为隔离符号的方法，支持尽最大努力从中间模式消除尽可能多的符号，并通过延迟处理来处理未知或部分已知的运算符。

摘要： A data access architecture may includes a mapping architecture for mapping data as may be used by an application to data as persisted in a database. Such a mapping architecture uses two types of “mapping views”—one for translating queries and the other for translating updates. A mechanism is provided that automatically generates query and update views from high-level mapping specifications. A validation may be performed to ensure that a mapping specification, when used in conjunction with a mapping architecture, allows data to “roundtrip” from the application to the database, without loss of data.

摘要： Described is programmatic access to persistent XML and relational data from applications based upon explicit mappings between object classes, XML schema types, and relations. The mappings are used in data access, that is, they drive query and update processing. A query may be processed into a query for accessing the XML data and another query for second type for accessing the relational data. Mappings support strongly-typed classes and loosely-typed classes, and may be conditional upon other data, may decouple query and update translation performed at runtime from schema translation used at compile time, and/or may be compiled into transformations that produce objects from XML data and transformations that produce XML data from objects. Mappings may be generated automatically or provided by the developer.

摘要： A sequence of storage devices of a data store may include one or more stripesets for storing data stripes of different lengths and of different types. Each data stripe may be stored in a prefix or other portion of a stripeset. Each data stripe may be identified by an array of addresses that identify each page of the data stripe on each included storage device. When a first storage device of a stripeset becomes full, the stripeset may be shifted by removing the full storage device from the stripeset, and adding a next storage device of the data store to the stripeset. A class variable may be associated with storage devices of a stripeset to identify the type of data that the stripeset can store. The class variable may be increased (or otherwise modified) when a computer stores data of a different class in the stripeset.

摘要： Computers are provided with a totally ordered, durable shared log. Shared storage is used and can be directly accessed by the computers over a network. Append-log operations are made atomic in the face of failures by committing provisional append ordering information onto a log. The log may comprise multiple flash packages or non-volatile memory devices, referred to as segments, although any shared storage device(s) may be used. Each log record is a multi-page stripe, where each page of a stripe is written to a different segment. Fault-tolerant protocol variants append stripes to the log, such that stripes are totally ordered in the log and each stripe is written atomically.
