All information systems process data and therefore, each system
needs mechanisms to access data. In this paper we will first define
a classification of information systems w.r.t. their requirements on
data access and second, develop and discuss different approaches in
order to fulfill these requirements. Emphasis will be given to data
intensive systems that are reading and writing huge amounts of data.
The overall application scenario is defined by engineering design
frameworks and data modeling using the STEP standard (ISO 10303).
Having classified arbitrary types of data sources, we will discuss
multiple CORBA-based data access strategies. They will be evaluated
and compared with Intra/Internet-based approaches using a modular
prototype system. This system has been built according to the Java
language mapping of the STEP data access interface (SDAI) which has
been co-developed by us.
