I am a junior level programmer and working from home. When I was surfing the net, I found a new tool which is used to compare two access/SQL databases from WBCSoftwareLab. It's name is "WBC-Access-DB compare - Tool to compare two Access Databases" and it is used to execute altered queries before or after comparison of two databases and check again. I am satisfied and downloaded this free of cost. Many other free downloadable DB tools are also available at WBCSoftwareLab.
If you too find such new tools in any DB applications, just share with me.
