- I understand the intentions of a database, being to streamline the data record-keeping of any organizations. And I understand the hardware needed to do such. The area I find myself the most lost in is the idea of programming the rules and structure of a database. In my head a database is a chart (or multiple charts) with fields that is used to store records. And then those records stored in one chart intertwine with other charts of course so we need to have relationships between the charts. Where I get lost is in the thought of programming a structure for the data to fit in. Are we making metaphysical locations to store data or are we just writing relationshipds between data that is stored on a plethora of different options?Project Synopsis: database management ABC Walk-in Clinic is located in a large metropolitan city in Canada. The clinic staff consists of ten doctors, six nurses, five office secretaries, two administrative assistants and one manager. First time Patients have to visit the clinic personally and fill a registration form that contains their personal and health related information. An office secretary would then enter that information in the computer based information system. Patients may become a permanent patient (at any time) for one of the doctors at the clinic by filling up necessary forms (they are called enrolled patients) or they may choose to come walk-in for every visit. (They usually called walk-in patients) Enrolled Patients may book their appointments online or by calling, the office and one of the secretaries would then book their appointment with their doctor on a particular day/time. Any booked appointment may be cancelled up to 24 hours in advance after which the clinic…What are the performance considerations when working with data binding in high-traffic or resource-intensive applications?

Course: Each course has a unique course code, a title, a description, and the number of credits. Enrollment: Each enrollment represents a student's registration in a specific course for a particular semester. It includes information about the grade received for that course. Professor: Each professor has a unique professor ID, a name, and an email address. Professors teach one or more courses. Create an ERD that represents the relationships between these entities.
