    • Methods and systems for optimizing queries in a multi-tenant store are described. In one embodiment, such a method includes retrieving data from a multi-tenant database system having a relational data store and a non-relational data store, receiving a request specifying data to be retrieved, retrieving one or more locations of the data to be retrieved, generating a database query based on the request, in which the database query specifies a plurality of data elements to be retrieved, the plurality of data elements including one or more data elements residing within the non-relational data store and one or more other data elements residing within the relational data store, generating an optimized database query having an optimized query syntax that is distinct from a query syntax of the database query, and executing the optimized database query against the multi-tenant database system to retrieve the data.

    • Network security is enhanced in a multi-tenant database network environment using a query plan detection module to continually poll the database system to locate and raise an alert for suspect query plans. Security also can be enhanced using a firewall system sitting between the application servers and the client systems that records user and organization information for each client request received, compares this with information included in a response from an application server, and verifies that the response is being sent to the appropriate user. Security also can be enhanced using a client-side firewall system with logic executing on the client system that verifies whether a response from an application server is being sent to the appropriate user system by comparing user and organization id information stored at the client with similar information in the response.
    • 在多租户数据库网络环境中,使用查询计划检测模块来增强网络安全性,以持续轮询数据库系统来定位并提出可疑查询计划的警报。 安全性也可以使用位于应用程序服务器和客户端系统之间的防火墙系统进行增强,记录每个接收到的客户端请求的用户和组织信息,并将其与应用程序服务器的响应中包含的信息进行比较,并验证响应是否正在 发送给适当的用户。 安全性也可以使用客户端防火墙系统进行增强,该系统在客户机系统上执行逻辑,通过比较客户端存储的用户和组织id信息与相似的信息来验证来自应用服务器的响应是否被发送到适当的用户系统 在回应中。
