A well-designed database will provide you with easy access to accurate and up-to-date information. However, database designing needs one to understand the business requirements. Complex database designs also need architects who understand the requested business processes. Because a proper design is essential for any business to achieve its goals, investing in time to the principles of a good database design makes sense.
Surprisingly, database design theory is one of the topics that most people avoid learning mostly due to lack of time. Some of those who attempt to learn sometimes give up due to the dry academic treatment that is given by most authors and teachers. However, if designing and creating databases is part of your day-to-day job, then you are treading on thin ice in case you don’t have a solid understanding of relational database design theory.
What is a Good Database Design?
The database design process is guided by some principles. The first principle is the duplication of data or redundant data is bad. This is because it increases the likelihood of inconsistencies and errors, and wastes space. The second principle is that the completeness and correctness of information is essential. In case a database has incorrect information, the reports pulled from the database will also contain incorrect information. This means that any decision made from such reports based on a skewed rationale.
Features of a good database design
- Helps to ensure accuracy and integrity of information
- Divides information into subject-based tables to minimize redundant data
- Accommodates the existing data processing and reporting needs
- It provides access to information that is required to be joined in the tables
The main idea behind relational database models is that a database consists of unordered tables that are connected to each other in a meaningful way. For a relational database to function, some basic rules have to be followed:
- Each table should have a unique name,
- Each table should contain multiple rows,
- Every row in the table should be unique,
- Each table should be awarded a key to identify the rows, and
- Each column should have a unique element name.
These rules are an important part of the database design. Specialists and people in the organization, including users and senior executives. ensure that the database supports day-to-day operations and provides information that the specialist can use to support decision-making database designs.

This training will enable your employees to:
- Determine the purpose of your database,
- Organize the required information,
