Introduction to Data Synchronisation Studio

Data Synchronisation Studio is a Application to connect and synchronise Data between systems.

DS3 tackles the concept of Import, Export and Synchronisation in a unique way. Rather than looking at events or messages in queues which are typically complicated distributed systems and error prone. DS3 takes the approach of Set based Reconciliation with instant Data preview and NO State. This allows DS3 to operate exactly the same way every time to guarantee consistency and high performance through set based data sets.

License Key Activation

Data Synchronisation Studio (Data Sync) is activated with your license key via your internet connection against The activation is refreshed automatically every 15 days to keep the activation alive.

When you first open Data Sync you will be presented with an activation window.

Activation Window

You then have 3 choices:

  • Sign In: Sign in to your account either browse for your license key or request and activate a trial license if you don't have a license key.
  • Enter License Key: If your license is registered to a different account, you can enter in the license key directly by clicking here
  • Continue: This will close the window but you will not enable any features.

If you close the window by mistake then you can re-open it by going to Help > Register License.
