摘要： A plurality of partitions can be defined in a database for a multi-tenant computing system provided on one or more processors such that each partition of the plurality of partitions is associated with only one business tenant of a set of business tenants supported by the multi-tenant system. The database can stored shared content that is shared among and accessible to all tenants of the multi-tenant computing system while tenant content for each business tenant can be stored in the database in one partition of the plurality of partitions. The one partition can be assigned to an associated business tenant. At least a portion of the tenant content can be unique to and associated with the associated business tenant. One or more errors can be generated to prevent tenant content associated with a first business tenant of the set of business tenants from being accessed by a second business tenant of the set of business tenants when an application code executed within the multi-tenant computing system comprises a construct that would otherwise enable cross-tenant access by the second business tenant to tenant content associated with the first business tenant. Related systems, methods, and computer program products are described.

摘要： A method for automating evaluation of grammars associated with one or more programming languages is disclosed. The computer system accesses first grammar data associated with a first grammar and second grammar data associated with a second grammar, wherein a grammar comprises one or more rules that define a programming language. The computer system determines from the first grammar data and the second grammar data whether the first grammar and the second grammar correspond to the same programming language. Determining further includes applying one or more transformational steps to both the first grammar data and the second grammar data. After each transformational step, the computer system determines whether the first and second grammar data correspond. In accordance with a determination that the first grammar data and the second grammar data correspond, the computer system determines that the first and second grammar both correspond to the same programming language.

摘要： Methods and apparatus, including computer program products, for measuring the performance of aspects of a complex data processing system. In one aspect, a method uses a dynamic synthetic benchmark to provide performance information for a program application running on a virtual machine. The benchmark in one implementation uses a load profile that includes information about instructions that make up the application, their call frequencies, and their workloads. Microbenchmarks of individual virtual machine instructions provide performance information about the virtual machine that is used with the load profile to synthesize a performance benchmark for the application.

摘要： System, method, and computer program product embodiments transform data from a first version, for example an initial version of a database, to a second version, for example a subsequent version of a database. An embodiment includes modifying the metadata of the data to include transformational clauses, each of which describes how a portion of the data in the first version is transformed to data in the second version. Another exemplary embodiment includes differentiating between rename and add/delete operations to reduce the amount of transformational clauses included in the metadata. For example, rename operations can be identified by ignoring commonly-named columns between two versions, and identifying columns where the name has changed between the two versions while the data type has not changed.
