Can we use Sinolta to provide Field Data capture functionality?

Yes. Field Data Capture is nothing but a set of calculated monthly data.
Use Automation to collect data from the field, from its Historian or from an external SQL database stored periodic or daily data.
Use Automation to convert the collected data to monthly data.
Store the monthly data in a set of CSV files.
Use Automation to create an Excel, HTML or a PDF file to display reports.
The automation logic can be set up to periodically or by a trigger to collect, process and report the desired data.
