Before data can be entered into a database, the storage structure needs to be defined. As a minimum, a database would need at least one table.
A data dictionary is a document that describes database objects such as tables, columns, and their corresponding data types. It provides information about the structure, relationships, and constraints of the database schema.

you would use a database? You would use it to store data
We would use in rather than on. Data is stored in a database, not on a database. Data is entered into a database not onto a database.
The number of fields in a database can vary widely depending on its design and purpose. Typically, a database table may have anywhere from a few fields to several dozen, depending on the complexity of the data being stored. To determine the exact number of fields in a specific database, one would need to examine its schema or structure directly.
The first object that must be created in a database is the database itself. It serves as the foundational structure that holds all other objects, such as tables, views, and indexes. Without the database, there would be no environment to store and manage these additional objects.
A cinema would use a database to efficiently manage and organize various aspects of its operations, such as tracking movie schedules, ticket sales, customer reservations, and inventory of concessions. A database enables quick access to real-time information, facilitating better decision-making and enhancing customer service. Additionally, it allows for data analysis to understand audience preferences and optimize marketing strategies. Overall, a database streamlines processes and improves overall efficiency in cinema management.
