1. Run the Tool:

• The tool is typically run from the command line with specific parameters to define the source and target databases. Here is a general format of the command you might use:
  shell DatabaseCompareTool.exe /source:PostgreSQL /target:SQLServer /sourceConnectionString:"[PostgreSQLConnectionString]" /targetConnectionString:"[SQLServerConnectionString]" /output:"C:\Path\To\OutputFile"
• Replace [PostgreSQLConnectionString] and [SQLServerConnectionString] with the actual connection strings for your PostgreSQL and SQL Server databases, respectively.
• Replace C:\Path\To\OutputFile with the path where you want the comparison results to be saved.

1. Example Command:

• If your PostgreSQL server is localhost and your database is pg_db, and your SQL Server is localhost with a database sql_db, the command might look something like this:
  shell DatabaseCompareTool.exe /source:PostgreSQL /target:SQLServer /sourceConnectionString:"Host=localhost;Port=5432;Username=yourusername;Password=yourpassword;Database=pg_db" /targetConnectionString:"Server=localhost;Database=sql_db;User Id=yourusername;Password=yourpassword" /output:"C:\ComparisonResults\results.txt"

1. Review the Results:

• After the comparison process is complete, review the output file specified in the command. This file will contain details about any discrepancies found between the PostgreSQL and SQL Server databases.
