01

The challenge

The call every systems administrator dreads: "the database will not open". Journal entries, invoices and payroll are locked inside the database files, and the system that read them has stopped or lost its licence.

The tools on the market are old, closed and expensive, and they do not honestly tell you which data is sound and which is inferred from a damaged block.

02

What we built

We built an engine that reads Oracle files directly, treating the original file as read-only with a fingerprint proving it never changed.

The key idea: a guess is never presented as fact. Every row comes out with one of three statuses: verified structurally, inferred from a damaged block and labelled as such, or rejected with a reason.

The engine was tested in a lab against real Oracle databases across several versions, with Arabic text and compressed tables, and now ships as a simple step-by-step Arabic Windows application.

03

The outcome

Organisations get their data back in a modern format with a verification report for every table, without running Oracle or buying a licence.
