How to Create a Bill of Materials in MS Access Using SQL for Stock Management?

In the realm of manufacturing and production, effective stock management is crucial for business success. One pivotal tool that assists in this process is the Bill of Materials (BOM). Essentially, a BOM details the components, parts, and materials required to create a product. This guide guides you through creating a BOM using MS Access and SQL.

Importance of a Bill of Materials

A Bill of Materials helps businesses in various ways:

Inventory Management: Track stock levels of components to ensure there's enough material to meet production demands.

Cost Management: Calculate the cost of each component to determine the overall product cost.

Production Planning: Schedule orders and procurement activities based on stock availability and production requirements.

Setting Up Your MS Access Database

Before executing SQL queries, set up your MS Access database appropriately.

Tables Structure

Create the following tables:

Components: To list all individual parts.

ComponentID (Primary Key)

ComponentName

UnitCost

StockLevel

Products: To list all the finished products.

ProductID (Primary Key)

ProductName

BOM: To map components to products.
