In databases, there are two main types: file databases and relational databases. When discussing tables, we focus on relational databases, where each table acts as a flat file containing attributes of a specific entity. These tables are interconnected through relationships. For example, in a business scenario, one might start with a simple flat file like a spreadsheet to keep track of orders. In this case, a table can be created to manage order numbers sequentially, paired with customer information and addresses. As the business grows, additional attributes can be included to track various aspects of orders, like products and payment details. Initially, orders might come from different customers, requiring the storage of their unique details, such as names and addresses. Organizing this data in tables ensures efficient retrieval and management as business operations expand.
