xSQL Data Compare for SQL Server runs on Windows operating systems that have the .NET framework 4.0 installed.
Comparison Engine - robust, highly efficient comparison engine compares millions of rows fast while tightly controlling resource utilization. There is no technical limit in the size of databases that SQL Server Data Compare can synchronize.
Modern GUI - SQL Server Data Compare's GUI reflects the latest standards in user interface design. Context sensitive ribbon, action panels with clear descriptions, asynchronous implementation of lengthy operations, detailed progress information and more.
One-click re-compare - SQL Server Data Compare maintains a comparison session history. A session is a persisted environment that contains all the data related to a comparison operation including databases and the respective credentials, comparison options, mapping rules, excluded objects and many more. It allows the end-user to repeat a comparison with a single click. Options control the way sessions are sorted and the max number of sessions that are persisted.
Custom mapping - the mapping rules feature allows you to customize the way database objects are paired together. Mapping rules include: "Schema mapping rules" that determine how the schemas are mapped; "Name mapping rules" that determine how the object names are mapped; and "Data mapping rules" that determine how data types are mapped.
Custom comparison keys - need to compare tables or views but they are showing as non-comparable because there is no primary key or unique indexes defined on them? Once xSQL Data Compare for SQL Server has analyzed the schema it will allow you to define a unique key (any combination of the fields of that table) to use for the comparison. The rows are paired based on the selected key.
Command Line utility - the included, highly configurable command line utility allows you to schedule comparison and synchronization operations via the Windows Task Scheduler, SQL Server Scheduler etc.
Full control over the comparison and synchronization - a wide array of options gives you granular control over the behavior of the comparison engine. Comparing views along with tables, analyzing table dependencies and arranging the synchronization script accordingly, comparing databases with different collations are just some of the available options.
Handling large databases - custom built algorithms handle serialization of both data rows and script fragments as needed ensuring strict control of the memory utilization.
Script execution engine - the proprietary, intelligent script execution engine ensures that very large t-sql scripts including scripts for binary columns and large text columns are executed successfully while providing continuous progress information and allowing you to safely interrupt the script if necessary.
Error handling - systematic error handling aims at eliminate unexpected / unexplained results. Non-critical errors are registered and reported but do not interrupt the operation. Errors are reported via dialog boxes or printed on the output panel. A full error log is created.
