Who is Data Engineer

Data engineers are responsible for finding trends in data sets and developing algorithms to help make raw data more useful to the enterprise.A data engineer transforms data into a useful format for analysis. Imagine that you’re a data engineer working on a simple competitor to Uber called Rebu. Your users have an app on their device through which they access your service. They request a ride to a destination through your app, which gets routed to a driver, who then picks them up and drops them off.

 

Roles & responsibilities of a Data Engineer

The data engineers design, build and install the data systems. These systems fuel machine learning and AI analytics. They also develop information processes for a whole host of data tasks. These include data acquisition, data transformation, and data modelling, among others.

 

The Data Architect: Their work allows data systems to ingest, integrate, and manage all the required sources of data for business insights and reporting. The work of a data architect may need in-depth knowledge of SQL, NoSQL, and XML, among other systems and tools

 

The Database Administrator: Database administrators help design and maintain database systems. They ensure that database systems function seamlessly for all users in an organization.

 

The Data Engineer: Data engineers understand several programming languages used in data science. These include the likes of Java, Python, and R. They know the ins-and-outs of SQL and NoSQL database systems. They also understand how to use distributed systems such as Hadoop. Having such a wide expanse of knowledge allows them to work with data architects, database administrators, and data scientists.

 

Uplatz provides this extensive Data Engineer Career Path training to make you well versed with the most important tools & technologies used in data engineering space.
