This is particularly true for the simulation of complex systems where the computational resources needed considerably increase with the model resolution and with the number of simulated entities. The development of such simulation systems, however, requires extra efforts compared to the conventional local ones. Example extra efforts are learning how to use the Distributed Simulation (DS) Standard (such as HLA) and the development of extra software for the synchronization and communication between the local and distributed environment. In this paper, we address the problem of defining a simulation language that can transparently support the development distributed simulation systems, by making the use of the DS standard transparent and also reducing the amount of extra software. The HLA transparent language we introduce is named jEQN, being Java-based and dealing with Extended Queueing Networks domains. The language approach, however, can be easily extended to any other DS Standard and modelling domain. {\textcopyright} 2008 IEEE.}, keywords = {Complex systems, Computational resources, Computer simulation languages, Computer software, Dielectric relaxation, Distributed environments, Distributed simulation systems, Distributed simulations, Distributed systems, Do-mains, Java programming language, Large scale systems, Linguistics, Model resolutions, Queueing networks, Simulation languages, Simulation systems, Software components, Standardization, Standards}, isbn = {9781424417872}, doi = {10.1109/ASC-ICSC.2008.4675405}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-58049176462\&partnerID=40\&md5=9610842bfbbce4f9f21f913927ec00c1}, author = {Andrea D{\textquoteright}Ambrogio and Gianni, D. and Iazeolla, G. and Pieroni, A.} } @article {D{\textquoteright}Ambrogio199749, title = {CORBA-based approach to design gateways for multidatabase systems}, journal = {Journal of Engineering and Applied Science}, year = {1997}, note = {cited By 0}, pages = {49-54}, publisher = {Cairo Univ, Cairo, Egypt}, abstract = {

A MDBS (Multi Data Base System) is a system that provides access to data from a collection of DBSs (Data Base Systems), called component DBSs, that are heterogeneous and distributed. The integration of the component DBSs into the MDBS is performed by a complex of functions termed gateway. This paper describes the design of a gateway based on the distributed object computing (DOC) approach, and compliant to the CORBA (Common Object Request Broker Architecture) standard. The approach is shown to introduce savings in design complexity and cost. The details of the approach are described in a gateway case study for the integration of a relational DBS into a MDBS.
