Data architecture is the cornerstone of the Data Engineering field and the foundation for your entire analytical strategy. This is because it creates the necessary structure to gather information and analyze it efficiently. Without a solid architecture, many difficulties arise along the path to understanding and improving your business.
And that’s not all! With the explosion of Artificial Intelligence in the world and its increasing penetration into companies, it’s important to note that advanced technologies, such as AI, machine learning, and LLM, also require good Data Engineering work. Therefore, first and foremost, it’s essential to understand the architecture.
In this article, we will discuss the key concepts of Data Architecture and how it influences companies’ analytical journey.
Fundamental Principles of Data Architecture
Some principles of Data Architecture, regardless of which model is adopted (Data Lake, Data Warehouse, or Data Lakehouse, for example), ensure that data maintains a standard of quality throughout the organization.
- Security: It’s important to avoid unauthorized access and alterations to preserve data integrity over time. For this, mechanisms such as primary keys, foreign keys, and data validation can be used.
- Reliability: To make informed decisions based on data analysis, your data must first be consistent and error-free. Cleaning and validation processes are fundamental, as well as establishing quality standards.
- Availability: When it comes to large operations and constant real-time analysis, it’s necessary to provide quick and continuous access to data. Best practices, such as regular backups and performance monitoring, ensure that data is always available when needed.
- Performance: An efficient architecture avoids delays and bottlenecks, ensuring fast and efficient data processing. To achieve this, you can explore different strategies, such as database indexing and data partitioning.
Stages of Building a Good Architecture
By now, you should understand why you need a reliable and secure repository for your data. It will be a source of truth for all your company’s decisions! But what are the stages of this process?
Data Extraction: Initially, it’s necessary to extract data from various sources to feed a repository. This may involve extracting data from transactional databases, services with APIs, industrial sensors, communication by specific protocols, web scraping, or even pre-existing files such as CSV or XLSX.
Data Transformation: After extraction, it’s necessary to transform the raw data to ensure its quality and consistency. Here, you can apply sanitization rules, data validation, and business rules to prepare the data for analysis.
Data Provisioning: Once transformed, it’s necessary to make the data available in a secure repository for consumption. That is, in file systems, databases, or structures such as data frames, which facilitate data manipulation.
Additionally, there are auxiliary stages intrinsic to this process: data storage and orchestration. Data must be stored efficiently and securely to ensure its integrity and availability. Likewise, it’s necessary to chain and schedule data pipeline activities so that execution is truly efficient.
