Currently, Omniscope is not a relational database, but an alternative to spreadsheets and other reporting tools for visualising, managing and communicating tabular data/ reporting views. Each .IOK file contains a single, totally 'flat' table of rows (records) and columns (fields)...plus embedded images, links, etc.

The internal structure of IOK files is proprietary and highly compressed.

Many individual files can be merged/joined to form a single Omniscope file, and Omniscope will re-perform these merges whenever any of the linked data source files changes. Omniscope files can be linked to each other, such that records in one file are linked to another, more detailed Omniscope file with a different (usually more granular) data structure.
