Data engineering is an essential field within software engineering that focuses on the practical application of data collection, storage, and retrieval, aimed at facilitating the analysis and understanding of large volumes of data. It encompasses a wide range of tasks and processes including but not limited to:
1. Data Collection: Gathering data from various sources such as databases, online services, APIs, or directly from users.
2. Data Storage: Efficient and scalable storage solutions for holding large datasets, which may involve databases (both SQL like MySQL, PostgreSQL and No-SQL like MongoDB, Cassandra), data lakes, or cloud storage services.
3. Data Cleansing: Improving the quality of data by cleaning it, which means removing or correcting inaccuracies, inconsistencies, and duplications in the data set.
4. Data Integration: Combining data from disparate sources into a coherent dataset, which involves resolving issues related to data format, structure, and coding.
5. Data Transformation: Converting data from one format or structure into another. This may involve aggregating, summarizing, or reshaping data to make it more suitable for analysis.
6. Data Modeling: The process of creating a data model for the data to be stored in a database. This includes designing how the data will be stored, connected, and accessed in a database management system.
7. Building and Managing Data Pipelines: Automating the flow of data from its source to its destination for storage, analysis, or visualization. This involves
