Abstract: A server system provided according to an aspect of the present disclosure receives validation rules for fields of a form, and stores the validation rules as metadata in a memory. When values are later received based on the form, the values are validated using the rules in the metadata. Any errors detected are notified to a user system from which the values are received. The values are forwarded to a corresponding application if no errors are detected. According to another aspect, a developer of the application provides an initial set of validation rules prior to the application being deployed at a customer site. The customer then specifies additional rules. The metadata stores both the initial rules and the additional rules. A user interface module validates each received value against any applicable rules present in the metadata.

Abstract: A customization includes a name of a module of source code in an existing generic version of application software, a specific position within the module, and a name of a file which contains additional software. An existing customized version of the application software is then prepared, to execute the additional software in executing the existing generic version at the existing specific position. When a new generic version of the application software is received, the existing customization is displayed if applicable to a module in the new generic version, followed optionally by receipt of an update to the existing specific position. On indication of user approval, a new customized version of the application software is prepared, to execute the additional software in executing the module in the new generic version, at the existing specific position or at an updated specific position, which depends on the optional receipt of the update.
