Time-Aware Systems You Can Trust

Build Smarter Software with Bi-Temporal Event Store

Bi-Temporal Event Store from globalsoft is an open-source, production-ready event store for building systems that are reliable, correctable, and fully traceable.

Unlike traditional systems, it doesn’t just track what happened, it tracks when it happened and when you knew about it.

This gives you:

Full auditability
Confidence with regulators
Safe, clean data corrections
Future-aware planning

Build systems that answer real business questions like:

What did we know?
When did we know it?
Can we trust it now?

Why It Matters to Business?

Modern organizations need more than a history log. They need to answer:

What did we know on this day?
When was this correction made?
What was true at the time vs. what we thought was true?
What will happen in the future on specific day?

Traditional databases can’t answer these questions. Bi-Temporal Event Store from globalsoft can. It introduces a bi-temporal data model:

Two Types of Time:

Transaction Time: when the system recorded the event
Valid Time: when the event was true in the real world

This enables: - Historical accuracy - Time-based business logic - Traceability for compliance and trust

Example: Salary Correction

An employee was meant to get a raise starting June 1, but HR entered it late on July 10. Most systems only track when the change was entered, making reports for June inaccurate. With a bi-temporal event store, you capture:

Transaction Time: July 10 (when it was recorded)
Valid Time: June 1 (when the raise should apply)

This lets you report what was known at the time or what should have been true — all without losing accuracy or traceability.
