It masks the hardware details, giving the user a single-image space system with transparent data transfer and uniform program interface.","PeriodicalId":393932,"journal":{"name":"Proceedings 36th International Conference on Technology of Object-Oriented Languages and Systems.

One way to manage the complexity is to abstract and model them. The authors propose a method of modeling Web application architecture with UML, in which the design of the Web application is described from different viewpoints and levels of abstraction by three models: business model, navigation model and implementation model. It is aimed at facilitating the design, implementation and maintenance of large, complex Web applications and the reuse of previously gathered design experience.","PeriodicalId":393932,"journal":{"name":"Proceedings 36th International Conference on Technology of Object-Oriented Languages and Systems.

Such spatiotemporal objects can be found in applications such as geographic information systems (GIS), environmental data management and multimedia databases. Traditional relational database technology is not suitable for managing spatiotemporal data, which are multi-dimensional with complex structures and behaviours. Spatiotemporal data can only be managed by the new generation of data management technologies such as object-oriented and object-relational databases. We present a comprehensive survey covering aspects from fundamental user requirements for spatiotemporal applications, spatiotemporal object modelling, object storage structures and techniques for manipulation of spatiotemporal objects such as multidimensional indexing, data structures, query evaluation strategies and architectures for spatiotemporal database management systems.","PeriodicalId":393932,"journal":{"name":"Proceedings 36th International Conference on Technology of Object-Oriented Languages and Systems.

The purpose of normalizing complex object schemes is not only to group objects into related relationships, but also to choose a structure for the information system which is a good representation of the semantic relationships among objects that already exist in the real world. Firstly, we define the object dependency (OD) based on the data dependencies among objects, and we present the properties of the OD. Then we define the object normal form, the normal object scheme tree and the normal object scheme forest, and show the properties of the object normal form. We show that the normal object scheme forest is the most desirable structure for complex object schemes. Then we present the algorithm MIMI for deriving a normal object scheme forest. Finally, we present and prove the properties of a normal object scheme forest produced by the MIMI algorithm under a set of conflict-free ODs.","PeriodicalId":393932,"journal":{"name":"Proceedings 36th International Conference on Technology of Object-Oriented Languages and Systems.

Tari et al., 1997)), in terms of a directed graph, the definition of directed graph in graph theory is extended according to the characters of the user interpretation and the requirement of the problem; the node in this directed graph may be either an ordinary node or a directed graph. The directed graph (having been extended) expressing the user interpretation, is said to be a GD-constraint graph. Based on this, the features of the GD-constraint graph corresponding to the user interpretation without conflicts are extracted. Finally, the sufficient and necessary condition under which the user interpretation doesn't contain conflicts is given, and a polynomial time recognition algorithm whose time complexity is O(m*n), is proposed on the basis of the sufficient and necessary condition. Next, the correctness of the algorithm is proved and the time complexity of the algorithm is analyzed.","PeriodicalId":393932,"journal":{"name":"Proceedings 36th International Conference on Technology of Object-Oriented Languages and Systems.

Change notification mechanisms are important for the concurrency of systems. Meanwhile, the core Web technology only offers very limited support for distributed applications.

Firstly, the system will become disordered without a perfect information management strategy when faced with the tremendous amount of information resources. Secondly, it is essential for the system to transmit a large amount of information in a secure and efficient way in a wide networking environment. Furthermore, a system with excellent compatibility and extensibility will be valuable in terms of system maintenance and update.

In the analysis phase, firstly, a requirement analysis activity ends by writing a requirement specification describing what the system under development is intended to do. Secondly, analysis models are developed, namely: Class Relationship Diagrams (CRDs) and the High Level-Class Relationship Diagram (HL-CRD) to capture the structural aspect of the system and object interaction diagrams (OIDs) and state transition diagrams (STDs) to capture its behavioural aspect to enhance and refine the CRD which is the core diagramming technique of HOOM. In the design phase, design enhancements are added to CRDs, implementation decisions are made and class specifications are written. In the coding phase the design deliverables are implemented.","PeriodicalId":393932,"journal":{"name":"Proceedings 36th International Conference on Technology of Object-Oriented Languages and Systems.
