Databases are a critical business tool because they organize information in a structured way, which makes it easier to access and manipulate. They also protect your data from unauthorized changes and can help ensure the integrity of your information.

A database can help you build the foundation for data-driven decision making, allowing your organization to run more efficiently and enable better business decisions. However, not all databases are created equal, and it’s important to choose one that meets your specific needs and the requirements of your applications.

The basics of a database design

A good database design begins with dividing all of your information into subject-based tables to reduce redundant data and to ensure that the correct information is stored. The information is then linked together as needed, so that all of your reports will provide you with the same, accurate information each time you query the system.

Normalization

A common part of the database design process, normalization helps you make sure that the data items you’ve gathered are properly organized. It can also identify any errors in the original representation, and can help you fix them before you put the system into production.

Data consistency

Whether the data is collected in a spreadsheet or through manual input, it’s crucial to ensure that all of your information is consistent. This helps prevent errors from occurring, and allows you to form more accurate decisions based on reliable information.

A well-designed database also helps you maintain data integrity by enforcing rules on how data is entered, retrieved, and stored, and by tracking changes. This is particularly important if your organization collects information from a variety of sources or uses multiple internal and external data collecting techniques.
