问题：
我需要一台适用于Linux的Microsoft Reporting Service 免费或现金。当然最好是免费的。
要求：
WYSIWYG Report Editor (for developer, don't care if that part only works on windows)
Ability to dynamically generate reports from the web
Usage of one or multiple database types (like MySQL, PostGre, Oracle, ODBC)
multiple file formats support (including HTML)
support for graphs/charts
scalable
有什么可能性？
