As Brian Swan has mentioned in his latest blog post, the ODBC database driver for SQL Server on Linux has been released. This is a huge step forward for directly connecting linux-based systems (and programming languages) to this popular Microsoft product.
The first beta release of the SQL Server ODBC Driver for Linux is available for download! As announced in October, the "Multiplatform Team" (a.k.a. the "MPlat Team") has released a preview version of a driver that will provide first-class access to SQL Server from applications running on Linux operating systems. The team is looking for feedback on this release to incorporate into their production-ready release, so try it out and let us know what you think.
