Skills measured
ETL
ETL stands for Extract, Transform, Load. It is a process in data engineering that involves extracting data from various sources, transforming the data into a format that is suitable for analysis or other purposes, and then loading the data into a target system such as a data warehouse or a data lake. ETL is often used to integrate data from different systems, clean and standardize the data, and make it available for analysis or reporting.
ADF
ADF stands for Azure Data Factory. It is a cloud-based data integration service that allows you to create, schedule, and orchestrate data pipelines that move and transform data between data stores and data sources. ADF enables you to build data pipelines that can ingest data from a wide variety of sources, including on-premises and cloud-based data stores, as well as perform transformations on the data before it is loaded into a destination data store.
Data Modelling
Data modeling is the process of designing a logical structure for a database. It involves identifying the entities (e.g., customers, products, orders) and the relationships between them, and defining the attributes (e.g., name, address, price) and the data types (e.g., text, number, date) for each entity. Data modeling is an important step in data engineering because it helps to ensure that the data is properly structured and can be effectively queried and analyzed.
Data Lake
A data lake is a centralized repository that allows you to store all your structured and unstructured data at any scale. A data lake enables you to store data in its raw and original format and provides a single point of access for data consumers to access and analyze data. Data lakes are often used in data engineering to store large amounts of data from various sources and to provide data analytics and machine learning capabilities.
Data Governance
Data governance is the process of establishing and maintaining control over the management, storage, and use of data within an organization. Data governance involves setting policies and procedures for data management, ensuring that data is accurate, consistent, and secure, and enforcing compliance with relevant regulations and laws. In data engineering, data governance is important because it helps to ensure the quality and integrity of the data that is used for analysis and decision-making.
