What is Data Engineering? Check out the answers to the 5 most common questions about Tech here!
Although data engineering is becoming indispensable, it is not a new approach. The ideas behind data engineering originated in batch and offline processing and still apply today. Many people are piqued about data engineering, the skills required to be a data engineer, and how they can apply data engineering to their business. Check out the answers to the 5 most common questions about data engineering below.
What is Data Engineering?
Data engineering refers to designing, building, and maintaining large-scale data processing systems. Data engineering involves collecting raw data from multiple sources, transforming the data into a more usable format, and then storing the data in a central location for consumption. Data engineering develops an enterprise-wide view of the organization’s data assets that address organizational objectives.
Who is a Data Engineer?
Data engineers are responsible for data collection, processing, storage, and retrieval. They work with a team to create data models that allow easy access to the data in question. A data engineer is responsible for maintaining the infrastructure used by data scientists to build models. They also create libraries that can assist in building models by integrating with existing frameworks and software. They also create interfaces that allow non-technical users to query raw data, check and maintain performance and data migration.
Why is Data Engineering important?
Data engineers are the glue that holds together the entire data pipeline. They build ETL code and data processing pipelines to cleanse and process data, ensure the accuracy of the information, and move it into a data warehouse. Data engineering enables the management of databases, submission, and monitoring of queries, and creating new data products. Data engineers also devise plans for disaster recovery and business continuity, working closely with IT teams to create backup plans for their projects. They also work closely with business partners to share the insights they’ve created from the raw data through visualization tools or machine learning applications.
What skills do I need to become a data engineer?
A data engineer’s job is an interesting blend of business and technological skills. A typical data engineer needs to be as comfortable with software development as with statistics, mathematics, and machine learning. The skills needed to be a data engineer include SQL or programming languages like Java, Python, or Scala. They also must understand file formats and databases and have basic IT skills. They also have to understand organizational needs and leverage big data technologies such as Hadoop, Hive, and Spark.
