Final answer:
A database integrates tables to store data, allowing for easy access, management, and updates. Data can include various types such as text and numbers, and the structured organization helps in efficient retrieval through queries.
Step-by-step explanation:
A database consists of integrated tables, which store data in a structured way. The tables within a database are designed to hold information about a specific subject or area, and they are capable of storing various types of data, including text, numbers, dates, and more. The advantage of using tables in databases is that the data can be easily accessed, managed, ordered, and updated.
For example, a school database might have a table for students with columns for student ID, name, grade level, and email address. Another table might store course information, such as course ID, course name, teacher, and room number. Relationships can be established between tables to create an organized structure, for instance, linking the students to the courses they are enrolled in.
Databases are used in numerous applications, from small businesses managing customer information to large corporations handling global transactions. The ability to query the database allows users to find specific data efficiently, such as retrieving all students in the 10th grade or finding all the courses taught by a particular teacher.
