data storage is the collective methods and technologies that capture and retain digital information on electromagnetic, optical or silicon-based storage media. Storage is used in offices, data centers, edge environments, remote locations, and people's homes. Storage is also an important component in mobile devices such as smartphones and tablets. Consumers and businesses rely on storage to preserve information ranging from personal photos to business-critical data.

Storage is frequently used to describe devices that connect to a computer -- either directly or over a network -- and that support the transfer of data through input/output (I/O) operations. Storage devices can include hard disk drives (HDDs), flash-based solid-state drives (SSDs), optical disc drives, tape systems , and other media types. (TechTarget 2023)

Database design basics

A properly designed database provides you with access to up-to-date, accurate information. Because a correct design is essential to achieving your goals in working with a database, investing the time required to learn the principles of good design makes sense. In the end, you are much more likely to end up with a database that meets your needs and can easily accommodate change.(Microsoft 2023)

The design process consists of the following steps:

• Determine the purpose of your database    

  This helps prepare you for the remaining steps.

• Find and organize the information required     

  Gather all of the types of information you might want to record in the database, such as product name and order number.

• Divide the information into tables    

  Divide your information items into major entities or subjects, such as Products or Orders. Each subject then becomes a table.

• Turn information items into columns    

  Decide what information you want to store in each table. Each item becomes a field, and is displayed as a column in the table. For example, an Employees table might include fields such as Last Name and Hire Date.

• Specify primary keys    

  Choose each table’s primary key. The primary key is a column that is used to uniquely identify each row. An example might be Product ID or Order ID.

• Set up the table relationships    

  Look at each table and decide how the data in one table is related to the data in other tables. Add fields to tables or create new tables to clarify the relationships, as necessary.

• Refine your design    

  Analyze your design for errors. Create the tables and add a few records of sample data. See if you can get the results you want from your tables. Make adjustments to the design, as needed.

• Apply the normalization rules    

  Apply the data normalization rules to see if your tables are structured correctly. Make adjustments to the tables, as needed.
