- Development
NSD uses the latest technologies in project development.
The normal life cycle of a project is:
- requirement catalogue editing
- functional demands validation
- application conceptual model editing using the proper analysis/modelling technologies (OMT, RUP, UML, Merise, SSADM)
- documentation editing according to the technical demands and selection of the technologies according to the restrictions (minimal number of users per application, response time, budget, maintenance, subsequent re-usage of the components)
- application development according to the technical documentation, the chosen architectures,
use of modern programming techniques (code re-utilization, inheritance, modularization)
- installation and testing
- application maintenance
We will assist the client in any of the stages above.
The technologies used so far are java-based, EJB, Struts, Servlets, JDBC, JSP, with professional solutions (IBM WEB Server as a web server, IBM DB2 as a back end system – and re-utilization of existing AS400 programs) and also with public license solutions (Mysql, Apache, Tomcat). The architectures of the applications are the classical ones (n-tiers) and on the client part we use javascrip full-browser compatible validation. Therefore, we guarantee a 100% portability of our applications!
- Technical department
The technical department has two main tasks:
- development of complete solutions for small and middle companies (network architecture, components and their compatibility), but also for big companies with complex needs (wireless electronic devices’ integration, embedded devices’ integration, personalized solutions such as VoIP phone center etc)
