We looked at the basics of using SQLite in three ways: directly, via an access layer, and via the SQLAlchemy ORM. We have to create SQL DDL statements; we can do this directly in our applications or in an access layer. We can also have DDL built by the SQLAlchemy class definitions. To manipulate data, we'll use SQL DML statements; we can do this directly in a procedural style, or we can use our own access layer or SQLAlchemy to create the SQL.

Overview of this book
Object-oriented programming (OOP) is a relatively complex discipline to master, and it can be difficult to see how general principles apply to each language's unique features. With the help of the latest edition of Mastering Objected-Oriented Python, you'll be shown how to effectively implement OOP in Python, and even explore Python 3.x.
Complete with practical examples, the book guides you through the advanced concepts of OOP in Python, and demonstrates how you can apply them to solve complex problems in OOP. You will learn how to create high-quality Python programs by exploring design alternatives and determining which design offers the best performance. Next, you'll work through special methods for handling simple object conversions and also learn about hashing and comparison of objects. As you cover later chapters, you'll discover how essential it is to locate the best algorithms and optimal data structures for developing robust solutions to programming problems with minimal computer processing. Finally, the book will assist you in leveraging various Python features by implementing object-oriented designs in your programs.
By the end of this book, you will have learned a number of alternate approaches with different attributes to confidently solve programming problems in Python.
