摘要： Described herein are techniques for supporting bi-temporal data in a key value cache system. An embodiment provides bi-temporal data as the basic functionality of a key value cache system. An embodiment provides a redesign of the core data structures of a key value cache system, adds bi-temporal data storage in the key value hashing structure, and provides a temporality-aware memory space manager. Embodiments can achieve the same performance as current key value cache systems for regular queries (that is, the queries that only access the current versions of data) while supporting bi-temporal data.

摘要： Embodiments of a method are described. In one embodiment, the method is a method for executing and supporting transactions. The method includes receiving a transaction comprising a command and data. The method includes writing the data to a transaction manager on a persistent memory device. The transaction manager also maintains a status of the transaction and reference to entries within memory that are manipulated by the transaction. The method also includes creating an in-memory log of the transaction in a first hash directory. The method includes committing a copy of the first hash directory to a second hash directory maintained on a persistent memory device.

摘要： A method, system and computer program product is disclosed for supporting role-based access control in a collaborative environment, wherein pluralities of users work together in a collaborative process using a software system. The method comprises componentizing the software system into a multitude of software components, and limiting access to specific software components to certain users based on roles assigned to the users as defined by a run-time state of the collaborative process. The set of components that a user can access is dynamic, that set can change based on the “context” or the step where the user is in a collaborative workflow/process. Thus, in comparison with traditional access control mechanisms, an embodiment of the invention combines three different elements: a) the set of components that comprise the application is partitioned in such a way as to make componentized role-based access control feasible, b) a method for specifying inter-component dependencies to enable role-based groups, and c) enabling the modification of the access privileges based on contextual information from a collaborative process.
摘要翻译：公开了用于在协作环境中支持基于角色的访问控制的方法，系统和计算机程序产品，其中多个用户使用软件系统在协作过程中一起工作。该方法包括将软件系统组合成多个软件组件，并且基于由协作过程的运行时状态定义的分配给用户的角色来限制对某些用户的特定软件组件的访问。用户可以访问的组件集合是动态的，该集合可以基于“上下文”或用户处于协作工作流/进程中的步骤而改变。因此，与传统的访问控制机制相比，本发明的实施例组合了三个不同的元素：a）构成应用的组件集合被划分成使组件化的基于角色的访问控制可行，b）用于指定组件间依赖性以启用基于角色的组，以及c）基于协作过程的上下文信息来启用对访问权限的修改。
