IBM Informix Training

IBM Informix Training is structured in such a way so as to cover all the aspects required to create index strategies to improve advanced Informix performance tuning. Informix also incorporates design concepts that are significantly different from relational platforms, resulting in extremely high levels of performance and availability, and minimal administrative overhead.
