I have a pivot table called user_store. It's used to establish a many to many relationship between the users table and the stores table and looks something like this:
user_id - int
store_id - int
user_age_range - string
I have another table called user_memberships. It's columns look like:
user_id - int
store_id - int
membership_cost - decimal
membership_expiration - date
I need to establish a relationship between the user_memberships table and the user_store pivot table using the user_id and store_id columns present in both tables.
How would I do this when the user_store table does not have its own model (since it's a pivot table)?
I have two tables. One is user and the other is category, I have written this Eloquent ORM query to retrieves data from category
$category = Category::where(['status'=>'active'])->orderBy('id','asc')->get();
In category table here has a field called user_id. I want to join the user table and want to retrieve the user name where category table 'user_id' == user table 'id'.
How can I do this in Laravel eloquent ORM without Foreign key And Multiple models.
In the below dimensional model, all the dimension table follows the star schema except the prod table, which is snowflaked and has prod_sub table as a child table. What is the strategical point to consider snowflaking a star schema?
Sales Table - Fact Table
Prod_id (fk)
Promo_id (fk)
store_id (fk)
Promo Table - Dimension Table
promo_id (pk)
Store Table - Dimension Table
store_id (pk)
Product Table - Dimension Table
Prod_id (pk)
prod_class_id (FK)
Prod_name
Prod_brand
Prod_sub Table- Dimension Table (snow flaked)
prod_class_id,
prod_class
prod_sub_class
prod_family
According to Kimball : Star Schema is the best way of designing a data model for reporting, You will get the best performance and also flexibility using such a model.
So no need to snowflake it.
Then your Product Table Dimension Table becomes :
Product Table - Dimension Table
Prod_id (pk)
Prod_name
Prod_brand
prod_class
prod_sub_class
prod_family
