摘要： A method for programming and executing long running transactions between interface devices and a server includes the steps of providing a predicate set and a transform set on the interface devices pursuant to an activity to be performed by the long running transaction, the predicate set defining conditions for which updates to states in accordance with the activity are to be made and the transform set for applying the updated states pursuant to the predicate set, committing the activity for processing upon establishment of communication with the server from the interface device, establishing communication with the server from the interface device to initiate the long running transaction, replaying the predicate set and the transform set for the server to determine if the long running transaction is capable of being committed on the server and if capable of being committed on the server, committing the long running transaction to update states of the server wherein a plurality of interface devices are capable of executing long running transactions concurrently while competing to update states of the same data on the server and while maintaining transactional consistency. A system for programming long running transactions is also disclosed.
摘要翻译：用于在接口设备和服务器之间编程和执行长时间运行的事务的方法包括以下步骤：根据由长时间运行的事务执行的活动，在接口设备上提供谓词集合和变换集合，所述谓词集定义条件根据活动对状态进行更新，以及根据谓词集合应用更新状态的变换集合，在与接口设备建立与服务器的通信时提交用于处理的活动，建立与服务器的通信从接口设备启动长时间运行的事务，重播服务器的谓词集和变换集，以确定长时间运行的事务是否能够在服务器上提交，并且如果能够在服务器上提交，则执行长时间运行事务以更新服务器的状态，其中多个接口 ace设备能够同时执行长时间运行的事务，同时竞争更新服务器上相同数据的状态，同时保持事务一致性。还公开了用于编程长时间运行的事务的系统。

摘要： A database manager, computer program product and methods for managing a database utilized by multiple applications. In one embodiment, the database manager performs a database record change to database records by a first application. The database manager branches the database records such that the database record change is visible to the first application and is not visible to one or more other applications accessing the database. The database manager can merge database record changes made by the other applications such that database schema changes made by the other applications are visible to the first application.
摘要翻译：数据库管理器，用于管理由多个应用程序使用的数据库的计算机程序产品和方法。在一个实施例中，数据库管理器通过第一应用执行对数据库记录的数据库记录更改。数据库管理器分支数据库记录，使得数据库记录更改对于第一个应用程序可见，对于访问数据库的一个或多个其他应用程序不可见。数据库管理器可以合并其他应用程序所做的数据库记录更改，使其他应用程序所做的数据库模式更改对第一个应用程序可见。

摘要： A method, system and computer program product for retrieving data records to a client computer. An identifier of a base query is received from the client computer. The base query is configured to select a set of data records from a database that the client computer has permission to access. A modifying clause is also received from the client computer. The modifying clause comprises a directive restricting the set of data records to a subset of data records. The modifying clause may optionally comprise an expression for sorting. A combined query is generated from the base query and the modifying clause. The query is configured to return the subset of data records. The combined query is further configured to sort the subset of data records based on the value of the expression if the expression is present. The combined query is executed at the database.

摘要： A method for manipulating objects in isolation, in accordance with the invention, includes providing a shared object, B, from an object provider for use on a distributed object system. A new class of objects are provided which include a facade object, Bf, for B and a versionable representation object, Bv, for B wherein Bf supports a same interface as B. B is permitted to be manipulated in a given context isolated from other contexts for the object B wherein the object provider and an object user are unaware of the production and manipulation of the new class of objects. Method invocations on Bf in the given context are delegated to Bv to associate an instance of Bv with the given context such that one or more versions of object B are persistently maintained in the distributed object system.
