Do you need to replicate data from various types of databases into a centralized database without a budget for expensive custom programming or large-scale integration? Do you need a standardized solution across your enterprise that provides access to accurate, real-time data stored in various databases whether SQL Server, Oracle, DB2 or other database platforms? Learn how Double-Take Share from Vision Solutions can resolve your heterogeneous datacenters' challenge of sharing data between on-premise or cloud databases in real-time for business intelligence, platform or database migrations, or any other data distribution need. Attendees will learn: • The challenges enterprises wrestle with when integrating structured data from a variety of database sources for centralized reporting, business intelligence, platform migrations, or other business needs. • Use cases for real-time database replication with transformation between Microsoft on-premise and cloud solutions, even between different databases, operating systems and hardware platforms. • The technical aspects of data sharing between databases in heterogeneous environments.

4. Common Data Sharing Scenarios
Data/Application integration
> Accelerate the sharing of data between applications
> Keep distributed operations in sync
> Distributed users need to see each other’s data in real time
Data centralization for warehousing, reporting, or BI
> Centralize data from one or multiple sources
> Real-time access to current data for reporting or BI
Feeding real time data to mission critical applications
> eCommerce

6. Change Data Capture (CDC)
Data is captured and shared as it changes, immediately and quickly
replicated to other databases as specified
Only changed data is transferred, so efficient
Automatically handles the extraction, transformation (if any) and load to
target database (no intervention or manual scripting)
Ensures write order consistency and guaranteed delivery

Ensures ongoing integrity
> Changes collected in queue

> Moved to target only after
committed on source
> Ensures write-order-
consistency retained
> Queues retained until
successfully applied
> No database table locking
• Ensures failure integrity
> Automatically detects
communications errors
> Alerts administrator
> Automatically recovers
the connection and
processes
> No data is lost

The Double-Take
driver sees bytes of I/O
en route to the file
system and copies
them into memory
As confirmation of the
write travels back to the
application, Double-Take
then sends the bytes to
the target
