Systems and methods for hosting variable schema data such as dynamic tables and columns in a fixed physical database schema. Standard objects, such as tables are provided for use by multiple tenants or organizations in a multi-tenant database system. Each organization may add or define custom fields for inclusion in a standard object. Custom fields for multiple tenants are stored in a single field within the object data structure, and this single field may contain different data types for each tenant. Indexing columns are also provided, wherein a tenant may designate a field for indexing. Data values for designated fields are copied to an index column, and each index column may include multiple data types. Each organization may also define custom objects including custom fields and indexing columns. Custom objects for multiple tenants are stored in a single custom object data structure. The primary key values for the single custom object table are globally unique, but also include an object-specific identifier which may be re-used among different entities.

In accordance with embodiments, there are provided mechanisms and methods for publicly providing web content of a tenant using a multi-tenant on-demand database service. These mechanisms and methods for publicly providing web content of a tenant using a multi-tenant on-demand database service can allow the web content to be published by a tenant using the multi-tenant on-demand database service for use by non-tenants of the multi-tenant on-demand database service.

An approach for debugging site errors in a multi-tenant database system is disclosed. An example method can include receiving a request from a site administrator to access an enhanced error message and determining if the site administrator is approved for viewing the enhanced error message by evaluating exceptions associated with the enhanced error message, the request, and the site administrator. The example method further includes modifying a detailed error message related to the request for generating the enhanced error message, and providing the enhanced error message to the site administrator based on the approval determination.

In accordance with embodiments, there are provided mechanisms and methods for allowing access to developed applications via a multi-tenant on-demand database service, in a controlled environment. These mechanisms and methods for providing such access can enable embodiments to provide additional control over the development process as well as the access of such developed applications. The ability of embodiments to provide such additional control may lead to an improved application development framework, etc.

A system and method for voice transmission over high level network protocols. On the Internet and the World Wide Web, such high level protocols are HTTP/TCP. The restrictions imposed by firewalls and proxy servers are avoided by using HTTP level connections to transmit voice data. In addition, packet delivery guarantees are obtained by using TCP instead of UDP. Variable compression based on silence detection takes advantage of the natural silences and pauses in human speech, thus reducing the delays in transmission caused by using HTTP/TCP. The silence detection includes the ability to bookend the voice data sent with small portions of silence to insure that the voice sounds natural. Finally, the voice data is transmitted to each client computer independently from a common circular list of voice data, thus insuring that all clients will stay current with the most recent voice data. The combination of these features enables simple, seamless, and interactive Internet conferencing.
