Elas ajudam a extrair dados de várias fontes, transformá-los no formato desejado e carregá-los nos sistemas de destino.

Data modeling is crucial for designing effective data architectures. Master techniques for conceptual, logical, and physical data modeling to ensure that your data architecture meets the needs of your organization and supports big data analytics.

As an architect, the first thing you need to have is design skills. I would recommend using C4 architecture techniques, in which your architecture design is divided into four stages. 1) Context 2) Container 3) Components 4) Code The entire architecture design becomes very simple, where you can define the connectivity with other systems, what is happening inside the platform, what all components are used, and how the stuffs are working inside components. Miro and Mural are two tools that are particularly well-suited to C4 architecture. Apart from architectural knowledge, you must understand how ETL and ELT work, how to create data streaming pipelines, and SQL and API knowledge to query data in SQL and NoSQL databases.

Acquire technical skills in relevant programming languages (such as Python, R, SQL) and big data processing frameworks (such as Apache Hadoop, Apache Spark). Learn how to work with large datasets, perform data cleansing and transformation, and optimize data processing workflows.

Once the system architecture design is complete, it is necessary to plan how the applications will be used for data storage and querying. Performance is achieved not only by designing a powerful hardware, but also by optimizing how data is consumed and stored. Some important concepts for this involve Sharding, also known as horizontal partitioning, which is useful when using distributed computing or clustered environments, and indexing for faster retrievals.

To master designing as a data architect, focus on honing several key skills. Start by understanding business requirements thoroughly to align technical solutions with organisational goals. Develop proficiency in data modeling techniques, including conceptual, logical, and physical modeling, to ensure databases are structured efficiently. Practice designing scalable and robust architectures that handle large volumes of data, utilising both relational and NoSQL databases where appropriate. Gain experience with ETL, explore cloud-based solutions for scalability and flexibility. Continuously refine your skills through hands-on projects and staying updated with emerging technologies to excel in designing comprehensive data architectures.

Mastering the design of scalable and reliable systems is crucial for managing big data in data architecture. This involves understanding and implementing sharding to distribute data across multiple databases, thereby balancing the load and improving system performance. Additionally, mastering indexing techniques is essential to enhance query performance significantly. A well-designed system must also prioritize data integrity and consistency, ensuring that the architecture supports transactional systems effectively. By focusing on these core principles, you can build robust databases capable of handling large volumes of data without compromising on speed or reliability.

My unique perspective emphasizes not only the scalability and flexibility offered by cloud platforms but also the transformative potential they bring to data architecture. By leveraging cloud services, organizations can access virtually unlimited compute and storage resources, enabling them to process and analyze vast amounts of data at scale. However, my approach goes beyond mere adoption; it focuses on optimizing cloud architectures for cost efficiency, security, and compliance while enabling seamless integration with on-premises infrastructure and legacy systems.

Embracing the cloud as a data architect involves mastering scalable databases / data lakes like Hadoop and azure data lake , NoSQL options like DynamoDB, and warehousing solutions such as MSSQL / Oracle DB. Use tools like Airflow or Informatica for ETL tasks and Lambda for serverless processing. Focus on security with IAM and encryption, optimize costs with monitoring tools, and leverage AI/ML services for advanced analytics. Continuous learning through certifications and community engagement ensures staying ahead in cloud-driven data architecture.

Their ability to scale resources dynamically is a game-changer for managing big data. Moreover, leveraging these platforms not only enhances flexibility but also introduces efficiencies in cost and operations, provided that one navigates their pricing structures and adheres to best practices for security and compliance effectively.

When we talk about Big Data, it seems incomplete without Cloud because Cloud plays an important role in provisioning the base infrastructure and PAAS services, which are the cherry on the cake for Big Data. The cloud provides powerful scaling capabilities, multiple storage solutions, and secure and reliable connectivity.

Yea, the cloud generally offers flexibility for managing Big Data, but controlling costs is crucial. FinOps provides clarity in cloud spending, enabling precise cost management through transparency, optimization, and collective responsibility. This ensures that every investment maximizes value and supports business objectives.

When data is introduced, the first thing that is discussed is security. To better understand and cover all aspects of security, I typically divide the topic into the categories listed below. 1) Authentication: Determine who has been allowed to access the system and data. 2) Authorization: Determine what level of control the user must have over the system or data. 3) Encryption: Encrypt data both in motion and at rest, and use the masking technique to hide sensitive information such as name, number, and address. 4) Auditing: carrying out periodic audits will allow you to ensure that everything is working properly. Apart from this, it is critical to understand regional and domain-specific rules and regulations such as GDPR and HIPAA.

When talking about security, we need to talk about privacy, hence you need to read more on Data Governance and how to apply the data governance policies. This allows you the include all aspect of Data (both machine & human) management.

I find it critical to obtain the C-Suite buy in regarding security in order for them to appreciate the ramifications of loose security. Showing them what is at risk without controls provides them with a scenario they can relate to. For example having all of their personal data available to every employee at the company and exposed on every file feed to every vendor.

Dependiendo de las normas legales de los diferentes países , es necesario como buena práctica el encriptado de datos sensibles que aseguren a los usuarios que los datos están protegidos y claramente contar con los niveles de seguridad establecidos para cada entidad , no sobra mencionar el uso del modelo OSI .
