When dealing with large datasets in Java applications, retrieving all records at once can be inefficient and resource-intensive. Instead, pagination is used to fetch data in manageable chunks, improving performance and user experience. This blog explores how to implement JDBC pagination effectively, using a single SQL's LIMIT and OFFSET clauses also via the implementation of PageRequest and PageResponse objects to optimize data retrieval in relational databases.

The DAO Factory Pattern is an advanced extension of the DAO (Data Access Object) Pattern that centralizes the creation and management of DAO instances. This approach improves flexibility, maintainability, and scalability in Java applications that interact with databases. It is particularly useful when working with multiple DAO implementations (e.g., JDBC, Hibernate, JPA).

JDBC (Java Database Connectivity) is the standard API in Java that connects with relational databases. The ResultSet is a key component of JDBC, allowing developers to retrieve and process query results. Optimizing the handling of ResultSet can improve performance and ensure efficient resource management.

The Data Access Object (DAO) pattern is a widely used design pattern in Java for managing database interactions in an efficient and structured manner. It separates the persistence logic from the business logic, improving code maintainability, reusability, and scalability. In this article, we will explore the DAO pattern, its advantages, and how to implement it in Java.

In Mockito, you cannot directly verify if a method of a superclass was called. Mockito works with mocks and spies to verify interactions with specific methods, but it doesn't have built-in support for verifying calls to superclass methods.

Object-Relational Mapping (ORM) is a programming technique used to convert data between incompatible type systems, such as databases and object-oriented programming languages. In the context of software development, ORM is often used to bridge the gap between relational databases and object-oriented programming languages, allowing developers to interact with a database using objects in their programming language of choice.
