Database Design Road Map

Needs Analysis: The first step is to understand the goals and requirements of database design. In this step, you will determine the purpose and functions of the database to be designed, what data will be stored, which data will be retrieved, data access needs and users’ access levels.

Relational Schema Design: A relational schema is a structural description of the data you will store in your database. In this step, you need to decide how each data group in your database will be represented as a table, what the columns in each table are, and what the relationships between the tables will be.

Normalization: Normalization is a method used to optimize the structures of the tables in your database. Normalization avoids database consistency and data duplication. In this step, you will normalize the tables in your database and apply them to normalization levels such as first normal form, second normal form, and third normal form.

Table Design: Table design involves physically creating the structure of the tables in your database. In this step, you will specify details such as columns, data types, keys, indexes, and other physical properties of each table.

Data Access and Security: In this step, you will determine data access and security, such as database users’ access levels and rights. At this stage, you can also define other security measures such as firewall and data backup strategies by creating user accounts and authorizations required for users.

Data Management: Data management includes the management and maintenance of data in the database. In this step, you will create data backups to maintain the consistency of the data, ensure that the data is stored correctly, and optimize the database when necessary.

As a result, the database design process is an important step for the proper storage and access of data.
