Abstract: A method for setting access rights to project data in an application by defining an area of authority for a user, includes: determining a plurality of fields of data for a project in the application; determining a topology of one or more fields, from among the determined plurality of fields, for which the area of authority is to be settable; setting an area of authority for a registered user of the application, based on a field of the determined topology; and preventing access by the registered user to data for which a value of the field does not comply with the set area of authority.

Abstract: A system for fetching resource data of parameters included in a view using a generic get data application programming interface (API) is provided. The system includes at least one processor configured to execute instructions to: make, from a first application, a get data API call for fetching the resource data, wherein an input of the get data API call includes a view identifier; obtain, in response to the API call, view details for the view, wherein the view details include identifiers of the parameters included in the view and identifiers of one or more tables in which the parameters are respectively included; send a request to a second application for resource data of at least one parameter, among the parameters, stored in at least one table associated with the second application, from among the one or more tables; and receive and display, on the view, the requested resource data.

Abstract: A system for saving history information of input data to parameters included in a view is provided. The system includes a processor configured to: output an instance of the view; obtain pre-stored view details for the view, including identifiers of the parameters and tables to which input data of the parameters included are to be stored; make a generic API call to save current input data of a parameter to a table, wherein an input to the API call includes the current input data and old data of the parameter; based on the current input data and the old data being different, store the current input data in the table, create history information of the current input data and store the history information in a history table.

Abstract: A method, performed by at least one processor, for adding user-defined custom fields to a user interface (UI) view of a previously-developed application, includes: outputting a first screen for creating or editing a UI view of the previously-developed application; receiving a user selection to add a new user input field to the UI view; and storing one or more parameters of the new user input field in association with a reserved field of a reserved database of the previously-developed application, such that values input to the new user input field during execution of the user interface view are saved to the reserved field. The previously-developed application includes a plurality of predefined user input fields predefined during application development, a corresponding plurality of predefined database fields mapped thereto, and the reserved database comprising a predetermined number of reserved fields for mapping to new user input fields added post-development.
