Techniques for implementing a non-relational database that makes efficient use of collections within the database. For one or more collections, two or more sub-collections can be created for storing documents. Each collection can be configured as a single partition entity or a partitioned entity within the database. Each sub-collection is identified by a sub-collection identifier. If the collection is configured as a partitioned entity, then a partition key can be determined for documents to be accessed in the collection. The partition key can be extended with the sub-collection ID to form a compound property (sub-collection ID, partition key) that determines placements of the respective documents in the identified sub-collection across partitions of the collection. If the collection is configured as a single partition entity, then a field for the partition key is ignored and the respective documents are placed in the identified sub-collection within the single partition of the collection.

A technique for enforcing uniqueness of property-value pairs in a schemaless data store includes receiving a request to uniquely store a property-value pair PVin a first collection of the data store. In response to receiving the request, a property-value pair PVis constructed that includes (a) a property on which the data store enforces uniqueness in a second collection of the data store and (b) a corresponding value that provides a formatted version of PV. The technique includes performing a store-if-unique operation configured to (i) generate a failing result in response to PValready existing in the second collection and (ii) store PVin the second collection in response to PVnot already existing in the second collection. If the store-if-unique operation fails, the request to store PVin the first collection is denied; otherwise, the request is granted.

The present invention is directed towards methods and systems for delivering applications from a desktop operating system. A delivery module may receive a request from a client device of a user for access to an application, and identify that a desktop session can host the requested application. An agent may extract presentation layer elements of the requested application from presentation layer elements of other components of the desktop session, and provide, via a presentation layer protocol, the isolated presentation layer elements in a first application session to the client device for display. The delivery module may receive a second request from the user for the application, identify that the application is hosted by the desktop session and delivered in the first application session, and provide a second application session of the application from the desktop session to the user responsive to the determination.
