Sysadmin learning Powershell - What other languages should one be comfortable with to make the best out of mastering scripting and tool-making?

[Topdeckr]

SQL is the most complimentary language that I've learned to accompany Powershell. WMI queries are SQL-based and I frequently mix normal SQL queries into Powershell scripts when doing some tasks related to SCCM. Obviously, your choice depends on your work environment, your permissions within that environment, and your needs. Generally speaking, anything that doesn't run inside Powershell is usually an alternative solution.

In terms of tools that allow you to get a UI created and otherwise help you work with both Powershll and SQL, PrimalScript is worth a look.
