Who is a Data Engineer?
A person who develops, builds, tests, and monitors the complete architecture of the large-scale processing system or data storing architecture is referred to as a Data Engineer. As a Data Engineer, you need to build massive repositories or reservoirs and play a major role in managing those repositories along with the data that is extracted through different digital processes.What does a Data Engineer do?
A Data Engineer is responsible for :● Design, develop, build, install, test, and monitor the complete data management and processing system.
● Look after the complete Extract, Transform, and Load (ETL) process.
● Create highly scalable, versatile, and fault-tolerant systems.
● Identify different opportunities for data acquisition.
● Find out optimal ways to improve data quality, reliability, and efficiency of the system created.
● Creating architectures in a way that is aligned according to the business requirements.
● Create a solution that is made by the integration of different languages and tools.
● For increasing efficiency and reducing costs, create data models with reduced system complexity.
● Deploy disaster recovery processes.
● Update the existing system with the latest data management tools and techniques to improve efficiency.
Responsibilities of a Data Engineer
Data Ingestion which includes collecting data from different sources that may be in different formats. Changing the raw data into structured data by different Data Transformation techniques. Data transformation techniques vary with factors like the source of data, the format of the data, and the type of output required.Building a data pipeline in such a way that Performance Optimization is carried out and the system built is highly scalable and efficient. To sum up the responsibilities, we get the key points which are as follows:
● Design, build and monitor data pipelines.
● Integrate and convert raw data into structured data according to the requirements of the business.
● To improve performance, use automation tools to automate the tasks and optimize data-delivery.
● Create an architecture such that it ingests, transforms, and stores data for business requirements.
Skills Required:
To become a successful Data Engineer, you are required to inculcate some of the key skills which are mentioned below.● Deep knowledge of Big Data tools such as HDFS (Hadoop Distributed File System), YARN, MapReduce, PIG & HIVE, Oozie, and more.
● A clear understanding of techniques that are SQL-based such as MySQL in order to structure, edit and control the data stored in the repositories.
● Apart from structured data, you are required to deal with unstructured and semi-structured data as well. You need proper knowledge of NoSQL techniques like Cassandra and MongoDB for this.
● For data sensitive systems, the knowledge of a real-time processing framework is crucial.
Apart from these skills, the knowledge of data warehousing solutions, database architectures, and a clear understanding of operating systems like MS Windows, UNIX, Solaris, or Linux is a must.
