Abstract: A method, an arrangement and a computer program product, for providing seamless IP mobility across a security boundary between two domains comprises a novel architecture of known network infrastructure components along with enabling client software on the user device. The specific client software as well as the novel architecture represents the invention. The method is based on the combined use of independent IP mobility systems in each of the two domains. The key is client software being able to operate with both mobility systems simultaneously. Moreover, communication takes place in such a way that the ordinary remote access security solution is in control of all access to the secure home domain of the user. The resulting method provides secure and seamless IP mobility in any domain with independent choice of mobility and security technologies.

Abstract: The present invention is directed to a database and database management system and method designed to store and manipulate any type of data and any combination of data types. The underlying data architecture is uniquely flexible, and thus to the DBMS, the data in the database will appear to be of a type consistent with the access method of the DBMS. Further, the present invention allows a number of simultaneous, different access methods to the same underlying data, delivering the ability to work with complex data within one easily managed system. One of the key aspects of the present invention is the "atomization" of the data. Atomization is the separation of the storage of data content from its definition, as well as from its occurrences or instances in the database. An atom is the most basic element in the database. Data content is stored in content atoms, data definitions are stored in type atoms, and each instance of the same data value/property is represented by instance atoms.
