Abstract: In embodiments, methods and systems for controlling access to custom objects are provided. These techniques for controlling access to custom objects can enable embodiments to utilize a key for the protection of the security of data that is to remain private while not compromising efficiency of a query. The key for a requested custom object is identified and then used so that only an appropriate portion of a custom entity share table is searched to locate access information. It is then determined whether the user can access at least a portion of the custom object, and the appropriate and allowed data is sent to the user.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for applying a group of instructions to metadata in the context of an on-demand database service. These mechanisms and methods for applying a group of instructions to metadata can enable embodiments that ensure that “all or none” of the operations corresponding to the grouped instructions are performed. The ability of embodiments to provide such feature can prevent a scenario where only a portion of a desired effect is accomplished which, in turn, may complicate any effort to undo the same.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for selecting amongst a plurality of processes to send a message (e.g. a message for updating an endpoint system, etc.). These mechanisms and methods for selecting amongst a plurality of processes to send a message can enable embodiments to utilize more than one queue for sending such message. The ability of embodiments to provide such multi-process feature can, in turn, prevent latency that typically accompanies a mounting number of messages.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for creating, exporting, viewing and testing, and importing custom applications in a multi-tenant database environment. These mechanisms and methods can enable embodiments to provide a vehicle for sharing applications across organizational boundaries. The ability to share applications across organizational boundaries can enable tenants in a multi-tenant database system, for example, to easily and efficiently import and export, and thus share, applications with other tenants in the multi-tenant environment.

Abstract: Methods and systems for simulating an online session between the client and a remote server when the client is offline including simulating a web services API to access information when the client is offline. The client includes a local interface that can communicate with the remote server. During an online session, the data and the functional logic that is invoked to manipulate the data reside on the remote server. As such, the user transmits instructions to view, create, update, delete, or otherwise modify portions of data through the local interface and subsequently through the underlying network. These instructions are ultimately received at the remote server, which then invokes the proper functional logic to perform the instructions in order to manipulate the data. An API is provided that is substantially identical to the web services API that is typically accessed over the internet, but which simulates online functionality when offline.
