What is the first step in data engineering?

Real-World Example

Working at a fintech company like FinSecure, the first task for a data engineer might involve understanding the types of transactions processed daily. By identifying the key data sources—such as payment gateways, user accounts, and transaction logs—you set the stage for building efficient data pipelines that ensure accurate and timely financial reporting.

Understand Business Requirements

The initial step in data engineering is to gather and comprehend the business requirements. This involves collaborating with stakeholders to determine what data is needed, how it will be used, and the goals it aims to achieve.

Key Activities

• Identify Stakeholders: Engage with teams like marketing, sales, and product development to understand their data needs.
• Define Objectives: Clearly outline what the data engineering efforts aim to accomplish, such as improving data accessibility or enabling real-time analytics.
• Determine Data Sources: Identify where the data will come from, whether it's internal databases, external APIs, or third-party services.

Assess and Plan Data Architecture

After understanding the requirements, the next step is to design the data architecture that will support these needs.

Key Components

• Data Ingestion: Plan how data will be collected from various sources.
• Data Storage: Decide on the databases or data lakes where data will be stored.
• Data Processing: Determine the tools and frameworks for processing and transforming data.
