Real time tools for transactional systems development
Florin Hartescu, Claudiu B. Danilov · 2002
Real time transactions are implemented by client-server applications, which must have a very good response time and which are particularly difficult to realize. We have created three instruments used for developing multi user software products that manage geographically distributed data. Client users have a graphical display of the database placed on the server (actually they have the data displayed on a map) and then can easily make queries by selecting with a mouse the region or the object in which they are interested. Multiple users can access the database concurrently for reading and updating by network, modem or serial cable.
