Once you have the requirements, all that interests you is the result of the business rule (the result for the question, is it available?). The requirements for a room to be available are a sort of business rule. How many rooms are available for this room type? I mentioned the room type (like suite or with balcony) because we don’t allocate specific rooms directly in the hotel we just get a certain number of rooms reserved from the hotel (at least that’s what I understood from someone who does have an online reservation system).
Is it currently available to be booked or is it being redecorated, fumigated for cockroaches or under repair? – What’s the status of the room? Has the room already been booked on the same days that you want it? Is it sold out? (sold out on your system or the hotel notified you that its sold out) You might need other types of information that will tell you if the room is available. So how do you know if the room is available to be booked? The hotel info – which hotel was used so that you can pay them later The date – which day has the room been booked What kind of information do I need to collect for the allocations? To know which rooms have already been booked and to not book them to someone else. To know which rooms the hotel needs to reserve for the customer. To know which rooms the customer allocated and on which dates. Why do I need to collect information about allocation details? What kind of information do I need to collect? You will do this by registering hotels and hotel rooms on your system and then letting the customer book them through a web portal. Many people do not take a few minutes to ask some simple but penetrating questions.įor example, your goal is to create an amazing online hotel reservation system. "Business rules represent policies, procedures and constraints regarding how an enterprise conducts its business." “Business rules describe the operations, definitions and constraints that apply to an organization in achieving its goals” Īs you can see, business rules help you “achieve your goals”. Please refer to the theory of the example and not the exact technical detail. Some of the table designs from that database were not ideally optimized and normalized. This example was taken from an actual database. It does this by recommending you apply business rules to the database. This article tries to explain how you can save time and effort on the development process by moving some of that development to the database.
MySQL is well known for great performance and it might be time to discover other parts of it that will speed up your over-all development process. While everyone tries to improve speed and performance in MySQL, other databases have realized that adding features that cut down on development time and improving time-to-market is what some people are looking for.
