I’m no expert in DigitalOcean, so I’m here to answer the last two questions.
It matters if the paid features in the Enterprise Edition (EE) is what you need.
You can take a look at Prices | SeaTable and check out the EE features. For 15 users we could have a special offer for you. Please contact firstname.lastname@example.org for a quotation.
A similar feature is called “Common datasets” in SeaTable. It’s more intelligent and intuitive than Airtable and lets you share a portion of your data across bases in different groups. In this screenshot there’s a small introduction:
SeaTable offers more data types and is more intelligent and reliable than Airtable, apart from the fact that SeaTable is the only solution that lets you self-host. Did you already know that we even have a nice script to let you easily migrate your bases from Airtable to SeaTable?
Yes, a CDS imported into a base can be synced (see screenshot below).
Note: Imported CDS have the CDS icon in front of their name.
Two important buts:
1.) The sync is not automatic. You need to hit “sync with dataset” to refresh the data in the imported CDS.
2.) It’s a one-way sync. Changes you make in the imported CDS are overwritten the next time you “sync”.
