What is the standard format for a MongoDB connection URI?

A standard MongoDB connection URI generally follows the pattern: `mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[database][?options]]`. When using SRV records (like with MongoDB Atlas), the format is `mongodb+srv://[username:password@]host[/?options]`, where the 'host' itself contains the hostname, domain name, and TLD.
