BuildAHome Architect Interview Questions and Answers

OOPS concepts are the principles of Object-Oriented Programming that help in designing and implementing software systems.

• Encapsulation - bundling of data and methods that operate on that data

• Inheritance - ability of a class to inherit properties and methods from a parent class

• Polymorphism - ability of objects to take on multiple forms or behaviors

• Abstraction - hiding of complex implementation details and providing a si

Abstraction is a fundamental concept in OOPS that allows hiding implementation details and focusing on essential features.

• Abstraction is the process of identifying essential features and ignoring the rest.

• It allows creating abstract classes and interfaces that can be implemented by concrete classes.

• Abstraction helps in achieving encapsulation and modularity in software design.

• Examples of abstraction include abstract cl...read more

Parameterize refers to the process of defining parameters or variables in a system or program.

• Parameterizing allows for greater flexibility and customization in a system or program.

• It can be used in various fields such as engineering, finance, and computer science.

• For example, in a computer program, parameterizing can allow the user to input values for certain variables, making the program more adaptable to different s

Tools for continuous integration include Jenkins, Travis CI, CircleCI, GitLab CI/CD, and Bamboo.

• Jenkins is a popular open-source tool for continuous integration and delivery

• Travis CI is a cloud-based continuous integration platform

• CircleCI is a cloud-based continuous integration and delivery platform

• GitLab CI/CD is a built-in continuous integration and delivery tool in GitLab

• Bamboo is a continuous integration and deplo

Designing test data content for different flavors of DB

• Identify the data types and structures for each DB flavor

• Create test data that covers all possible scenarios and edge cases

• Ensure data consistency and accuracy across all DB flavors

• Consider performance and scalability factors for distributed DBs

• Include mainframe-specific data such as EBCDIC encoding and packed decimal formats

New technologies of DBMS are constantly emerging to improve data management and analysis.

• New SQL databases like CockroachDB and TiDB are gaining popularity for their scalability and distributed architecture.

• NoSQL databases like MongoDB and Cassandra are widely used for their flexibility and ability to handle unstructured data.

• Graph databases like Neo4j and OrientDB are becoming popular for their ability to handle compl...read more

Terraform is an open-source infrastructure as code software tool that allows users to define and provision a data center infrastructure.

• Terraform is used to automate the creation, modification, and deletion of infrastructure resources.

• It supports multiple cloud providers such as AWS, Azure, and Google Cloud Platform.

• Terraform uses a declarative language called HashiCorp Configuration Language (HCL) to define infrastruc...read more
