The scope of the work is to create an environment and the standards to implement a Local Dynamic Map (LDM) concept. The current situation is characterized that applications directly exchanging their information with the respective counterpart. Parallel applications exchanging their information in the same way. Therefore, information used by multiple applications has to be re-transmitted each time and creates a huge amount of data traffic. This leads finally to the situation where communication channels become overloaded and/or specific applications cannot be executed anymore due to the nonavailability of connection resource. The way out of this crucial situation is given if a common and coordinated local data store concept is implemented. This concept radically changes the way applications are developed and implemented. If an application is requesting information, it is requested first from the local data store, and only if the information is not available locally it is requested and transferred from the external source via the air-link. In this case, several provisions have to be given: - The access to the data base has to be unified and standardized for all applications - The data elements and its attributes used have to be harmonized and unambiguously defined - Means to maintain the content and integrity of the data store, and means to keep the content up to date have to be provided - Means to apply local regulations for privacy and security have to be developed - Last but not least the stakeholder-, user- and application-requirements have to be derived and included in the development
