Rather than maintaining the same staff or specific item every time in inventory transactional details, it actually holds one specific reference of those master tables which are maintained by some administrator of the shop or organization. Now considering two key master tables like Inventory and Sales_Staff, both the tables maintaining main store details of any specific item in that shop or organization, whereas Sales_Staff maintained all the staff details who are working on that shop or organization. Now Invoice should generate from some inventory details where a quantity of entire inquiry has been stored for one entire shop or organization.
In the above example, Invoice is the main transactional table, where all the transactional data has been stored successfully for every invoice generation on individual customers or end-user, it actually stored all the invoice data successfully for any kind of reference.
Inventory_ID (Foreign Key of Inventory Primary Key) SalesStaff_ID( Foreign Key of Sales_Staff Primary Key) As examples, we are going to consider three tables who are involved for inventory controlling system, assume three are interrelated. Also, it needs to maintain a more strict relationship with those child tables which additionally impacted for any kind of data manipulation activity like inserting to or deleting from that specific inventory.Suppose we can considering one Inventory Controlling System – in that case, we have to maintain one very strict relationship between all the tables who involved with given more description related to inventory. If we consider any relational design which is very common that maintain a strict relationship between all the related tables defined in the database.But that is not a true statement, relational database’s main agenda to avoid any kind of confusion or complication in between multiple tables involved with that specific database, where it helps a developer to maintain and verify easily without any struggle. From the specific definition of the relational database, people are thinking it’s too critical for maintaining and will create confusion.Relation Control System of MySQL relational database : In this application, SQL (Structured Query Language) programming language is used to create, update, delete & manage the tables and its contents, as MySQL is supported with the basic SQL queries.
