    • A method for providing optimized data representation of relations for in-memory database query processing is disclosed. The method seeks to optimize the use of the available memory by encoding relations on which the in-memory database query processing is performed and by employing auxiliary structures to maintain performance. Relations are encoded based on data patterns in one or more attribute-columns of the relation and the encoding that is selected is suited to a particular type of data in the column. Members of a set of auxiliary structures are selected based on the benefit the structure can provide and the cost of the structure in terms of the amount of memory used. Encoding of the relations is performed in real-time while query processing occurs, using locks to eliminate conflicts between the query processing and encoding.
    • 公开了一种用于提供用于内存数据库查询处理的关系的优化数据表示的方法。 该方法寻求通过对执行内存数据库查询处理的关系进行编码并通过采用辅助结构来维持性能来优化对可用存储器的使用。 关系根据关系的一个或多个属性列中的数据模式进行编码,并且所选编码适合列中特定类型的数据。 一组辅助结构的成员是根据结构可以提供的好处和结构在所用内存数量方面的成本来选择的。 关系的编码在查询处理发生时实时执行,使用锁来消除查询处理和编码之间的冲突。

    • Techniques for supporting access controls on application-specific operations performed by an application include receiving first data at a server distinct from the application. The first data describes a first set of privileges for performing a first set of application-specific operations. Second data is also received at the server. The second data associates a first user of the application with a privilege in the first set of privileges. In response to receiving a request at the server from the application, it is determined whether a particular user may have the application perform a particular application-specific operation based on the first data and the second data. The request indicates the particular user and the particular application-specific operation. A response is sent to the application. The response indicates whether the particular user may have the application perform the particular application-specific operation.
    • 用于支持由应用执行的特定于应用的操作的访问控制的技术包括在不同于该应用的服务器处接收第一数据。 第一个数据描述了执行第一组应用程序特定操作的第一组权限。 服务器也收到第二个数据。 第二数据将应用程序的第一用户与第一组权限中的特权相关联。 响应于从应用程序在服务器处接收到请求,确定特定用户是否可以使应用程序基于第一数据和第二数据执行特定的特定应用程序操作。 该请求指示特定用户和特定应用程序特定的操作。 响应发送到应用程序。 响应指示特定用户是否可以使应用程序执行特定的应用程序特定操作。
