Hi,
In order to access Microsoft SQL server database from Denodo Platform, I would perform the following steps in Virtual DataPort Administration Tool:
1. Firstly, create a [JDBC](https://community.denodo.com/docs/html/browse/latest/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources#jdbc-sources) datasource by following the instructions provided in the similar Q&A mentioned [here](https://community.denodo.com/answers/question/details?questionId=9060g000000TQnaAAG&title=Error+connecting+to+SQL+Server).
2. Next, create a [base view](https://community.denodo.com/docs/html/browse/latest/vdp/administration/creating_data_sources_and_base_views/jdbc_sources/jdbc_sources#creating-base-views-from-a-jdbc-data-source) over it to be able to query this base view or combine its data with data from other views.
Hope this helps!
