Hi Rahul,
You did not mention if your website is based on .NET or JAVA. In either cases, you can use execute SQL statements against the HANA Information models and use the results in your website.
Please find a link here for blog on the :NET connectivity to HANA. Regarding the JAVA connectivity, you can use the JDBC drivers and establish the connectivity to HANA Information models. Please look into the document posted here for the same.
Hope this helps.
Regards,
Ravi
