An entity is like a table. It contains rows and columns that store data relating to a specific element. In other words, these are relational elements. They're related to one another. These entities could be physical representations like an employee, a customer, or a product. Or they could be conceptual like an order, an invoice or a quotation. Entities then store data in a table-like format against the attributes or features related to the element.
For example, an online store could hold customer's data in a customer entity containing specific attributes relating to the customer. These attributes could include first name, last name, date of birth, and email. They could also have product data stored in a product entity against attributes like product code, description, price, and availability. In the relational database world, these entities are known as relations or tables. The attributes become the columns of the table. Each table row represents an instance of that entity. As an example, let's take the entities from the online store example that you just explored. These two examples could be combined into a list of orders the store received from his customers. Within a database, this data could be rendered as an order table or entity. The data can be organized into rows that contain a unique order number. The name of the customer who placed the order, the product that they ordered, and the price of that product. There are many ways to organize data in a database. Relational databases aren't the only kind of databases that you'll encounter. As a Database Engineer, you'll work with many different types of databases. Here's a few common examples of other types of databases. An object-oriented database is where data is stored in the form of objects instead of tables or relations. An example of this kind of database could be an online bookstore. The store's database could render authors, customers, books, and publishers as classes like sets or categories. The objects or instances of these classes would then hold the actual data. Graph databases store data in the form of nodes. In this case, entities like customers, orders, and products are represented as nodes. The relationships between them are represented as edges. Finally, there's document databases where data is stored as JSON or JavaScript Object Notation objects. The data is organized into collections like tables. Within each collection a documents written in JSON that record data. In this example, customer documents are held in a customer collection while ordering product documents are stored in the ordering product collections. Where are the databases themselves stored? A database can be hosted on a dedicated machine within the premises of an organization, or it could be hosted on the Cloud. Cloud databases are currently a more popular choice. This is because they allow you to store, manage, and retrieve data to a Cloud platform and access data through the Internet. They all provide a lower-cost option for data management and other similar options. You should now understand the concept of a database. You should also be able to identify examples of databases and demonstrate how data is organized within a database. Great start. You'll be storing and managing data in no time.
