What is the best way to store data that is dynamic in nature using MySQL? Let's say I have a table in which one item is "dynamic". For some entries I need to store one value, but for others it could be one hundred values. For example let's say I have the following simple table:
CREATE TABLE manager
(
name char(50),
worker_1_name(50),
worker_2_name(50),
...
worker_N_name(50)
);
Clearly, this is not an ideal way to set up a database. Because I have to accommodate the largest group that a manager could potentially have, I am wasting a lot of space in the database. What I would prefer is to have a table that I can use as a member of another table (like I would do in C++ through inheritance) that can be used by the "manager" table to handle the variable number of employees. It might look something like this.
CREATE TABLE manager
(
name char(50),
underlings WORKERS
);
CREATE TABLE WORKERS
(
name char(50),
);
I would like to be able to add a variable number of workers to each manager. Is this possible or am I constrained to enumerating all the possible number of employees even though I will use the full complement only rarely?
