The project architecture follows a microservices approach with a RESTful API. The flow involves data retrieval, processing, and storage.

• The project is divided into multiple microservices that communicate with each other through a RESTful API.

• Data is retrieved from various sources and processed by the microservices before being stored in a database.

• The microservices are deployed in containers using Docker and managed by Kubernetes.

• The flow involves the user interacting with th...read more

An object is a real-world entity that has state and behavior.

• Objects are instances of classes in object-oriented programming.

• They have attributes (data) and methods (functions).

• For example, a car object may have attributes like color, model, and speed, and methods like accelerate and brake.

I have used python packages like Pandas, NumPy, Matplotlib, and Scikit-learn for data manipulation, analysis, visualization, and machine learning tasks.

• Pandas - for data manipulation and analysis

• NumPy - for numerical computing

• Matplotlib - for data visualization

• Scikit-learn - for machine learning tasks

OOPS concepts refer to Object-Oriented Programming principles like Inheritance, Encapsulation, Polymorphism, and Abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex implementation details and showing only the necessary features.

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.

• Example: Overloading a method with different parameter types is a form of compile-time ...read more

Severity refers to the impact of a bug on the system, while priority refers to the urgency of fixing it.

• Severity is the measure of how much a bug affects the system's functionality.

• Priority is the measure of how urgently a bug needs to be fixed.

• Severity is usually categorized as low, medium, high, or critical.

• Priority is usually categorized as low, medium, high, or immediate.

• For example, a bug that causes the system to crash would have high severity, but if it only affects a ...read more

Data warehousing is the process of collecting, storing, and managing data from various sources for analysis and reporting.

• Data warehousing involves extracting data from multiple sources and consolidating it into a central repository.

• It is used for data analysis, reporting, and decision-making purposes.

• Data warehouses are designed for query and analysis rather than transaction processing.

• Examples of data warehousing tools include Amazon Redshift, Snowflake, and Google BigQuery...read more

SCD type 2 stands for slowly changing dimension type 2, a method used in data warehousing to track historical data changes.

• SCD type 2 is used to maintain historical data by creating new records for changes in dimension attributes.

• It involves adding a new row to the dimension table with a new surrogate key for each change.

• The old record is marked as inactive with an end date, while the new record has a start date.

• This method allows for tracking changes over time and analyzing ...read more

STLC cycle stands for Software Testing Life Cycle, which is a series of steps performed to ensure the quality of software.

• STLC involves planning, designing, executing, and reporting on tests.

• It includes phases like requirement analysis, test planning, test design, test execution, and test closure.

• Each phase has specific objectives and deliverables to ensure the quality of the software.

• STLC helps in identifying defects early in the software development process.

• Example: In requ...read more
