ARCHITECTURE
The LUCOS tools are based on a distributed
client-server architecture, the clients of which
can be used from anywhere in the Internet.

VISUALIZATION CLIENT - ViCA
The ViCA client application makes a revolutionary
use of the WWW to support data visualization

• Developed in Java and accessed in the WWW
• Users can build their own visualization panels
• Numerous different chart types to choose from
• Interactive, always up-to-date visualization
• Supports navigation within and between levels

ViCA stores all definitions in the Metrics Server
and updates the panels with the latest data every
time the panels are accessed.
METRICS SERVER - MESS
The Metrics Server acts as a central manager for
all LUCOS Tools. It is a HTTPD-like multithreaded
server developed in C, supporting user
authentication and all common database
operations. All clients communicate with the MESS
using a protocol based on HTTP.
DATA SOURCES
No additional data collection is required. All
existing measurement data sources can be used and
combined in visualization.

• Data sources can be distributed anywhere in the
  Internet
• Data sources are connected to MESS using external
  data modules
• Support for Solid, Sybase, and any ODBC compliant
  DBMS
• Support for MS Project and MS Excel
