This persistent and structured way of storing data is simply called a database, and the data itself is stored using tables. Each table consists of columns and rows, with a look and feel similar to Microsoft Excel.
SQLite is based on the C language and a related API (RDBMS) in the market. The C language, for example, is easy to understand and is based on the fundamentals of database design with RDBMS. However, learning the actual API will benefit your skills and understanding.
In order to understand the API, you will have to learn the components that make up the database to improve your knowledge. Understanding data structures, SQL transactions, concurrency, and data-locking mechanisms, and creating good optimized queries will help you design great database systems.
Lastly, you need to put this understanding into some software code for the app you write and see how it is integrated and executed. The API language extension will be discussed further in this chapter.
