In a computer system () that launches application services for predetermined roles, a service-to-role assignment is customized in a target table. The user inserts a CD-ROM with master and reference tables, and the system automatically provides the target table. The master table () stores a first assignment () of application services (S,-) to roles (RO), and stores a second assignment () of service attributes (SA), such as language or industry branch, of the application services (S). The reference table () stores reference attributes (REA) for each application service (S) in the master table. The service representations for each role (RO) are forwarded from the master table () into the target table () if service and reference attributes match.

Method, computer program product and article of manufacture for providing service-to-role assignment to launch application services in role-based computer system

A role-based computer system has a first processor with a computer program () and has further processors with application systems (Sy, Sy, Sy) and application services (Se). The program generates a start instruction for the further processors to execute the services by consecutively receiving a log-in identification from the user and looking up in a first assignment table () for a role (Ro), looking up in a second assignment table () to determine logical services (LSe) assigned to the role; and looking up in a second assignment table to determine a pointer (P(Sy/Se)) to the services (Se) that are assigned to the logical service. The pointer has first and second portions to identify the application system (Sy) and the application service (Se), respectively, and becomes part of the start instruction ().

Computer program product method and computer in role-based application systems

A client computer and a server computer communicate via a network; the server computer receives user identification via the client computer that is selectively a first device or a second device. The server computer stores at least first and second application services for a single predetermined application class, wherein the first and second application services are adapted to client computer type. Upon receiving user identification, the server computer further receives a device attribute from the client computer, compares the device attribute with reference attributes, and selectively sends a representation of the first application service or of the second application service to the client computer according to the device attribute.

Automatically selecting application services for communicating data

The present invention discloses a method, computer program product and system for adjusting roles in a computer system () that launch application services (-) by a first user who is assigned to at least one role. A first role () calls a second role () by reference (). Both roles comprise representations of applications services () and (). When representations in the second role are modified, for example, application services are added (), a delta list () for the first reference is automatically created to conditionally prevent the first role () from referencing to at least some of the modified representations of the second role (). This is achieved by using a rule database () containing rules about application services that are mutually exclusive and checking for conflicts between the representations of the first role and modified, second role. A second user, e.g. a system administrator, can accept or reject automatically created delta entries () in the delta list ().
