Hello people,

I have a question about linked lists.

If i have a table with projects. Lets say 100 projects.
And i have a table tasks. Lets say 1000 tasks.

Now i can define the table:

projectTasks
columns projectid, taskId

or define the table:

taskProjects
columns taskId, projectId

does it matter?
for example in search speed?
Is there best practice?

thanks.

No, it does not matter in which order you reference both outer tables (performance wise). What will be of importance for performance matter is whether you place indices on your foreign keys or not.

And, as a side note, this has nothing to do with linked lists. This is called a many-to-many relationship.
