You're developing an advanced web-based tool for managing and manipulating data in a relational database system which stores, updates or deletes information of different entities over time periods from various sources such as social media (e.g., Facebook) or email exchanges between employees (in order to perform complex queries on this data. Your problem is: A group of friends are planning a surprise birthday party for one of their classmates who has been sick for the past month due to an accident at work. They want to plan it in such a way that everyone can attend and enjoy, but they also need to manage complex dietary restrictions due to allergies or health concerns among some guests. In addition to these constraints: - There should be zero waste of ingredients used beyond what's allowed for the dish, - The dish has to be prepared in less than 2 hours, - You need a recipe that includes at least three different dietary restrictions (e. xylitic acid reflux), and serves as an appetizing prelude to a themed event with a side of gluten-free bread.
