Abstract: Provided is a method, system, and program for managing access to data objects by multiple user programs over a network. A page is generated including at least one editable field of data from at least one data object. An initial value is calculated from the at least one data object and the page and the initial value are transmitted to one user program over the network. The page and the initial value are received from the user program, wherein the received page includes modified data in at least one editable field. A current value is calculated from the at least one data object after receiving the page and a determination is made as to whether the initial value transmitted with the received page is different than the current value. If the initial and current values match, then the data object is updated with the modified data included in the received page.

Abstract: Provided is a method, system, and program for managing information for an application program. The information includes an information class having a plurality of attributes values. The application program maintains multiple information class instances and wherein each instance includes at least one of the plurality of attribute values. User input is received indicating a plurality of information class instances and for each information class instance at least one attribute value. A main directory is generated for the application program. For each information class instance received from the user, a subdirectory is generated from the main directory for the information class instance and, for each received attribute value for the information class instance, one attribute file is generated providing the at least one attribute value. Each generated attribute file is stored in the subdirectory of the information class instance for which the attribute value is provided.
