Web page "metadata"?

Question

I haven’t worked with websites for sharepoint before, but you need to make changes to the web page, which should be distributed to some 700 websites. This is a change to one of the properties of the web part; the value needs to be changed. Is there a way to get the metadata for the web part and modify it directly in the database (I assume where it is stored.)?

Here is the scenario: Webpart contains a list of document types (internal type) with comma-delimited ones that it should display. Now there is a new document. types to add to all 700 websites. I need a way to list sites, get metadata for web parts, and add these new types of documents to a web page. Currently, they go manually to each site, click on edit, enter a new type of document and save it.
