1) A professor can teach many courses. (This is obvious). However, I get stuck in the second rule. 2) On a given semester, a course can be offered on different schedules, each of those offerings can be taught by a different professor. For example a typical freshman course on calculus has about 100 students every semester.

For example a typical freshman course on calculus has about 100 students every semester. The course is divided into 4 sections, each has 25 students and a different professor. Course { course_code prof_id course_name Primary key (course_code, prof_id) } Professor { prof_id prof_name }
Alternatively if we want professors with the names of the courses they teach (or have taught) outside of their department. Show activity on this post. I would use a left join here, and only involve the professor and course tables. The left join option lets us display a message should a given professor have no courses associated with him.

How to create a student database using Gravity Forms and Posts Table ProUse Gravity Forms to create a submission form.Store the student information as a custom post type in WordPress.Display the student database in a table on the front-end of your website.
Junction table. When you need to establish a many-to-many relationship between two or more tables, the simplest way is to use a Junction Table. A Junction table in a database, also referred to as a Bridge table or Associative Table, bridges the tables together by referencing the primary keys of each data table.
Some common examples of one-to-many relationships are: A car maker makes many different models, but a particular car model is built only by a single car maker. One customer may make several purchases, but each purchase is made by a single customer.
The student database includes basic information including address, sibling names and grades, parents, and contact information. This database is linked to all of the student's school classes and activities. Additional information regarding billing, accounts, and medical history are easily added by administrators.
A student database management system allows schools to save and access these records as needed by them, thus simplifying the work of the school administration team.
Relational database systems usually don't allow you to implement a direct many-to-many relationship between two tables.
Note: Minimum of three tables are required in the Many to Many relationships.
By definition, a many-to-many relationship is where more than one record in a table is related to more than one record in another table.
• When we say there is a 1:m relationship between two entities, it. means that for each occurrence of one entity there is one or many. occurrences of a related entity.
In dimensional modelling, a bridge table is a table which connects a fact table to a dimension, in order to bring the grain of the fact table down to the grain of the dimension.
Relationships are the established associations between two or more tables. Relationships are based on common fields from more than one table, often involving primary and foreign keys. A primary key is the field (or fields) that is used to uniquely identify each record in a table.
