Oracle's new SQL Developer 1.1 software allows query developers to browse competing SQL databases, a big plus in increasingly heterogeneous data environments.
We've seen differing reports this morning about which databases are supported in 1.1 -- clearly, Microsoft's SQL Server is on the list; other reports have IBM's DB2 and MySQL supported by the new software.
We are most taken by the news of MySQL support, since so much open source software is written in the LAMP stack. Getting blog data out of WordPress and into a more robust knowledge management system is just one example of the need for data-sharing toolsets.
Integration is often touted as a key upside to SaaS, so look for continued improvement in this area.
