Optimize database configuration by adjusting cache size and memory allocation
Avoid using SELECT * and instead specify the required columns
Use JOINs judiciously and avoid nested queries
Use EXPLAIN to analyze que
OOP in cloud systems allows for modular and scalable code.
OOP principles like inheritance and polymorphism can be used to create reusable and adaptable code.
Cloud systems often use microservices architecture, which can be implemented using OOP.
OOP can also help with encapsulation and abstraction, making code more secure and easier to maintain.
Examples of OOP languages used in cloud systems include Java, Python, and C#.

Main concepts of OOP include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit (object).
Inheritance: Creating new classes based on existing classes, allowing for code reuse.
Polymorphism: Objects of different classes can be treated as objects of a common superclass.
Abstraction: Hiding complex implementation details and showing o

Thread life cycle includes new, runnable, running, blocked, and terminated states.
Thread is created in 'new' state
It becomes 'runnable' when start() method is called
Thread enters 'running' state when CPU starts executing its run() method
It can go to 'blocked' state if it's waiting for a resource
Finally, thread reaches 'terminated' state when run() method completes or stop() method is called
Hash map is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hash map consists of an array of buckets, each containing a linked list of key-value pairs.
When inserting a key-value pair, the hash function is used to determine the index of the bucket where the pair should be stored.
To retrieve a value, the hash function is used to find the corresponding bucket...

Common types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column
Types of arrays in PHP include indexed arrays, associative arrays, and multidimensional arrays.
Indexed arrays: default type where each element is assigned a numeric index starting from 0.
Associative arrays: elements are assigned a specific key instead of numeric index.
Multidimensional arrays: arrays within arrays, creating a matrix-like structure.
Example: $indexedArray = [1, 2, 3]; $associativeArray = ['key1' => 'value...

Solid Principles are a set of design principles for writing maintainable and scalable software.
Solid Principles consist of five principles: Single Responsibility Principle, Open/Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle.
Single Responsibility Principle states that a class should have only one reason to change.
Open/Closed Principle states that sof...
Abstraction focuses on hiding implementation details, while interface defines a contract for classes to follow.
Abstraction allows us to focus on the essential features of an object, while hiding unnecessary details.
Interface defines a set of methods that a class must implement, providing a contract for how the class should behave.
Abstraction is achieved through abstract classes and interfaces in object-oriented program...
