He will discuss how IT has evolved from a cost center to a strategic asset and how to help an IT department embrace its new role in fueling growth and driving innovation. In the SOA arena, TechEd features a session that asks, “Will SOA replace ERP?” Microsoft Dynamics applications and BizTalk software will be part of this discussion about “Real World SOA.”Another session entitled, “Open Source Software in Enterprise Development,” ponders the role of open source and whether companies can manage licensing and support issues. TechEd also will feature discussion on the next release of the SQL Server database and how it will evolve to go beyond relational data and OLAP to support digital data types of the future.
