DAO

Data access objects (DAOs) are a design pattern used in software development to abstract the interaction with a database. A DAO encapsulates the logic for accessing and manipulating data from a specific data source, such as a relational database or a NoSQL database. DAOs provide a layer of abstraction between the application and the database, making it easier to develop and maintain applications that interact with data.

Why Learn About DAOs?

There are several reasons why you might want to learn about DAOs:

• To improve your software development skills: DAOs are a valuable design pattern that can help you write more maintainable and scalable applications. By learning about DAOs, you can improve your overall software development skills.
• To work with databases: If you work with databases, it is likely that you will need to use DAOs at some point. By learning about DAOs, you can gain a better understanding of how to interact with databases and how to write efficient and effective database queries.
• To pursue a career in data science or software engineering: DAOs are a fundamental concept in data science and software engineering. By learning about DAOs, you can open up new career opportunities in these fields.
