Is anyone familiar with the Enterprise Application Integrator (EAI) tools, like Microsoft BizTalk 2004, for example? We are looking at an EAI tool, does anyone have any suggestions as the good ones on the market that they use or have experience with? Also, does anyone use an ETL tool other than DTS? If so, please let me know what tool you use, how you feel about it and if you reccommend it. Thanks.
