Abstract: A database tier maintains and provides access to a database. An application tier receives and responds to requests for a form. The form includes data defining a first UI control for displaying a first value from the database and a second UI control for displaying a second value from the database that is dependent upon the first value. A client tier renders the form to show the first value in the first UI control and to show the second value in the second UI control. The client tier also detects a modification to the first value and causes an updated second value to be generated in response to detecting the modification to the first value. The updated second value is displayed by way of the second UI control. The updated second value is generated at the client tier, the application tier, the database tier, or at a combined application/database tier.

Abstract: An application module generates a query that may involve retrieving data from a local data storage source or from an external data storage source. The application module retrieves metadata to form a query tree stored in the local data storage source and uses the query tree to ascertain one or more sub-queries necessary to complete the query and whether the necessary data for each sub-query is stored locally or externally. Based on the location of the data to complete a sub-query, the application module uses the services of an internal query processing layer if external data is involved for the sub-query. The application module uses the services of a query processing layer in the local data storage source if the data is local. Once all the sub-queries associated with the query tree are performed, then the overall query results are returned to the application module.

Abstract: Creating web application using cloud-based friction-free databases without web hosting knowledge. User credentials are received at a web application service for initiating a web application task via client software. The user credentials are analyzed to determine whether to grant the user permission to initiate the requested web application task. The web application task is initiated when the permission is granted. Data associated with the initiated web application task is received at the web application service for analysis of the data to host and render a web application based solely on received data provided without basis of web hosting knowledge.
