Where can I find a CMS, similar to google sheets, for simultaneous editing by multiple users?

Question

CMS

Prompt CMS for the organization of tabular databases. Requirements:
1. admin section with creation/modification of tables/fields, etc.
2. client side, the ability to add records, view, filter by all fields.
Writing yourself is not an option. Not "writer". Google spreadsheets is also not desirable, ideally roll the system onto your own web server so that the data is local.
I would like something more interface-oriented, so that the client part is "for ordinary people (adding records, editing, viewing)".
At the moment, a tablet is used in Excel, which lies in the dropbox. This eliminates the possibility of more than one person working at the same time.
