In SQL Server, you can create up to 32 triggers on a table.

• SQL Server allows up to 32 triggers per table

• Triggers can be of different types like DML triggers, DDL triggers, and logon triggers

• Each trigger can be defined for INSERT, UPDATE, or DELETE operations

SOLID principles are design principles in Java that promote software design that is easy to understand, maintain, and extend.

• S - Single Responsibility Principle: A class should have only one reason to change.

• O - Open-Closed Principle: Software entities should be open for extension but closed for modification.

• L - Liskov Substitution Principle: Subtypes must be substitutable for their base types.

• I - Interface Segregation Principle: Clients should not be forced to depend on inte...read more

A procedure is a set of instructions that performs a specific task, while a function returns a value after performing a specific task.

• Procedures do not return a value, while functions do.

• Functions can be called within expressions, while procedures cannot.

• Functions are used to calculate and return a value, while procedures are used to perform an action.

• Example: Procedure - a set of instructions to display a message on the screen. Function - a set of instructions to calculate t...read more

Data analytics focuses on analyzing data to gain insights, data engineering involves building and maintaining data pipelines, and data science combines both to create predictive models.

• Data analytics involves analyzing data to gain insights and make data-driven decisions

• Data engineering focuses on building and maintaining data pipelines to ensure data is accessible and reliable

Software Testing Process in DBMS involves testing the functionality, performance, and security of the database management system.

• Identifying test scenarios based on requirements

• Creating test cases to validate data integrity

• Executing test cases to uncover bugs and issues

• Performing regression testing to ensure changes do not impact existing functionality

• Conducting performance testing to assess database speed and efficiency

Integration testing is a type of testing where individual units are combined and tested as a group.

• It involves testing the interactions between different modules or components of a system.

• It ensures that the integrated system functions correctly as a whole.

• It can be performed at different levels of the software development process, such as module, system, or acceptance testing.

• Examples include testing the integration between a database and a web application, or between differ...read more

Bug life cycle is the process of identifying, reporting, fixing, and verifying software defects.

• Bug is identified by testers or users

• Bug is reported to developers

• Developers fix the bug

• Testers verify the fix

• Bug is closed if verified or reopened if not

• Bug can be reopened at any stage of the cycle

Overfitting in decision trees occurs when the model learns noise in the training data rather than the underlying pattern.

• Overfitting happens when the decision tree is too complex and captures noise in the training data.

• It leads to poor generalization on unseen data, as the model is too specific to the training set.

• To prevent overfitting, techniques like pruning, setting a minimum number of samples per leaf, or using ensemble methods like Random Forest can be used.

A neuron is a basic unit of a neural network that receives input, processes it, and produces an output.

• Neurons are inspired by biological neurons in the human brain.

• They receive input signals, apply weights to them, sum them up, and pass the result through an activation function.

• Neurons are organized in layers in a neural network, with each layer performing specific tasks.

• In deep learning, multiple layers of neurons are used to learn complex patterns and relationships in data...read more

The number of onboarding per month varies depending on the hiring needs and company size.

• Number of onboarding per month can range from 10 to 50 or more, depending on the organization's size and hiring goals.

• Seasonal variations or project-based hiring can also impact the number of onboarding per month.

• Tracking and analyzing onboarding data can help in identifying trends and optimizing the recruitment process.

The question is asking about SQL commands: DELETE, TRUNCATE, and DROP.

• DELETE is used to remove specific rows from a table based on a condition.

• TRUNCATE is used to remove all rows from a table, but the table structure remains.

• DROP is used to remove an entire table from the database.

I have handled vendors in various industries including technology, office supplies, and catering.

• Managed relationships with technology vendors for software and hardware purchases

• Coordinated orders with office supply vendors for stationery and equipment

• Organized catering services for company events through various food vendors

Angular is a front-end web framework that allows developers to build dynamic web applications.

• Angular uses TypeScript for building applications.

• It follows the MVC (Model-View-Controller) architecture.

• Angular provides features like data binding, dependency injection, and routing.

• Components are the building blocks of Angular applications.

• Angular CLI (Command Line Interface) is used for creating and managing Angular projects.

Bagging is a machine learning ensemble technique where multiple models are trained on different subsets of the training data and their predictions are combined.

• Bagging stands for Bootstrap Aggregating.

• It helps reduce overfitting by combining the predictions of multiple models.

• Random Forest is a popular algorithm that uses bagging by training multiple decision trees on random subsets of the data.

Children should be encouraged to eat a balanced diet with a variety of foods to ensure they get all the necessary nutrients for growth and development.

• Encourage children to eat a variety of fruits and vegetables for vitamins and minerals.

• Include whole grains and lean proteins in their diet for energy and muscle development.
