    • Secure database access may be provided. First, a first schema associated with a database having a second schema may be defined. Next, a user type may be defined. The user type may comprise a user type that does not require a log-in. The defined user type may then be associated with the defined first schema. Next, at least one permission may be granted to the user type to the database on a database level. The at least one permission may comprise a create procedure permission, a create table permission, or a create function permission. Then permission to the second schema may be denied to the user type. Next, a procedure may be received comprising a procedure that poses a high security risk to the database. The received procedure may then be executed as the defined user type. The received procedure may be executed using a wrapper procedure.
    • 可以提供安全的数据库访问。 首先,可以定义与具有第二模式的数据库相关联的第一模式。 接下来,可以定义用户类型。 用户类型可以包括不需要登录的用户类型。 然后,所定义的用户类型可以与所定义的第一模式相关联。 接下来,可以在数据库级别向数据库授予至少一个权限给用户类型。 该至少一个许可可以包括创建过程许可,创建表许可或创建功能许可。 那么对第二个模式的许可可能被拒绝给用户类型。 接下来,可以接收包括对数据库带来高安全风险的过程的过程。 所接收的过程然后可以作为定义的用户类型来执行。 所接收的过程可以使用包装程序来执行。

    • Architecture includes for translating server calculations into client application formulas. The architecture determines dependencies, performs formulae translation, and processes data retrieval queries using the translated formulae. In one implementation, the architecture translates performance management server calculations into spreadsheet application formulas so that the impact of changes can be reflected immediately. Moreover, this technique does not require updating and querying of the performance management server. An algorithm is provided that allows translation of the backend formula (e.g., MDX—multidimensional expressions) directly into the spreadsheet application such that the impact on calculated values by an input change can be reflected instantaneously in the sheet.
    • 架构包括用于将服务器计算转换为客户端应用程序公式。 架构确定依赖关系,执行公式转换,并使用转换的公式处理数据检索查询。 在一个实现中,架构将性能管理服务器计算转换为电子表格应用程序公式,以便可以立即反映更改的影响。 此外,该技术不需要更新和查询性能管理服务器。 提供了一种算法,其允许将后端公式(例如,MDX多维表达式)直接转换到电子表格应用程序中,使得通过输入变化对计算值的影响可以立即反映在片材中。
