Now, let's dive into the item_pedido table. This table is the bridge between the pedido (order) and detalhes_item_pedido tables, giving us a clear view of what's included in each order. Think of it as the shopping cart – it lists each item a customer has added to their order. The item_pedido table includes fields such as id, id_pedido, nome_produto (product name), quantidade (quantity), id_produto, and preco (price). The id field serves as the primary key, uniquely identifying each item in the order. The id_pedido field is a foreign key linking back to the pedido table, so we know which order this item belongs to. The nome_produto field stores the name of the product, while quantidade indicates how many of that product were ordered. The id_produto field is another foreign key, this time linking to the produtos table, which we'll explore later. This link ensures we know exactly which product was ordered. Finally, the preco field stores the price of the item. This table is crucial for calculating the total cost of an order and for tracking inventory. By linking to both the pedido and produtos tables, the item_pedido table provides a comprehensive view of each item within an order. This makes it easier to generate reports, manage stock levels, and handle customer inquiries. The relationship between these tables is essential for ensuring data consistency and accuracy. Understanding this table is key to understanding how orders are processed and tracked within the Minuto Sabor system. It's a central piece in the puzzle of order management.

4. Pedido (Order) Table

Alright, let's talk about the pedido table, which is all about storing the main details of each order placed. Think of this table as the central hub for order information. It keeps track of who placed the order, when it was placed, and the total amount. The pedido table includes fields like id, id_cliente, data_pedido (order date), and total. The id field is the primary key, uniquely identifying each order. The id_cliente field is a foreign key linking back to the cliente table, so we know who placed the order. If this field is NULL, it might indicate a guest order. The data_pedido field stores the date and time when the order was placed, which is automatically captured using the CURRENT_TIMESTAMP default value. The total field, a DECIMAL type, stores the total cost of the order. This table is the core of the order management system. It provides a concise overview of each order, including its status, customer details, and total amount. The relationship between the pedido table and other tables, like item_pedido and cliente, is crucial for retrieving detailed information about an order. For example, by joining pedido with item_pedido, we can see all the items included in a specific order. Similarly, joining with the cliente table allows us to retrieve customer information for a particular order. This table is essential for generating reports, tracking order history, and managing customer relationships. Understanding the pedido table is key to understanding how Minuto Sabor manages its orders from start to finish. It's the foundation for a smooth and efficient ordering process.

5. Produtos (Products) Table

Now, let's move on to the produtos table. This is where all the delicious items on the Minuto Sabor menu are stored. Think of it as the digital menu card, listing everything from appetizers to desserts. The produtos table includes fields like id, nome (name), descricao (description), preco (price), criado_em (created at), and imagem (image). The id field is the primary key, uniquely identifying each product. The nome field stores the name of the product, while the descricao field provides a detailed description. The preco field, a DECIMAL type, stores the price of the product. The criado_em field automatically records the date and time when the product was added to the database, using the CURRENT_TIMESTAMP default value. The imagem field stores the file name of the product image. This table is the backbone of the product catalog. It allows Minuto Sabor to manage its menu items efficiently, including updating prices, descriptions, and images. The produtos table is linked to the item_pedido table, which allows us to track which products are being ordered.

The relationships between the tables in the Minuto Sabor database are what tie everything together, allowing us to efficiently retrieve and manage data. Let's break down these connections:

• Cliente and Pedido: A one-to-many relationship. One customer can place multiple orders. The id_cliente field in the pedido table acts as a foreign key, linking each order to a specific customer.
• Pedido and Item_Pedido: A one-to-many relationship. One order can contain multiple items. The id_pedido field in the item_pedido table is a foreign key, linking each item to an order.
• Item_Pedido and Produtos: A one-to-one relationship. Each item in an order corresponds to a specific product. The id_produto field in the item_pedido table is a foreign key, linking each item to a product.
• Item_Pedido and Detalhes_Item_Pedido: A one-to-many relationship. One item in an order can have multiple details (e.g., additions, complements). The id_item field in the detalhes_item_pedido table is a foreign key, linking each detail to an item.

These relationships ensure data integrity and consistency. For example, if a customer is deleted from the cliente table, their orders in the pedido table might need to be handled appropriately (e.g., deleted or reassigned). Similarly, if a product is removed from the produtos table, the corresponding items in the item_pedido table should be updated or removed. Understanding these relationships is crucial for writing efficient queries and for maintaining the integrity of the database. They allow us to retrieve complex information by joining tables together, such as all the items in a specific order or all the orders placed by a particular customer. This relational structure is the foundation of a well-designed database, enabling efficient data management and retrieval.
