1. Programming Languages
Like data analysts and scientists, data engineers must have strong programming experience. The most famous programming languages are Java, Python, and SQL/NoSQL:
Java programming language
Most tools and solutions for big data are written in Java. Also, Java allows the building of real-time data streaming platforms to complete challenging computational tasks and automatically visualize insights.
Here are some tips on how to hire an outsourced Java development company.
Python Programming Language
Python is a universal coding language that contains high-level data structures. This language can use data engineers to write Extract, Transform, Load (ETL) scripts and create data pipelines. In addition, Python is used for multiple artificial intelligence (AI) and machine learning applications.
SQL and NoSQL
The ideal data engineering team should have experience with SQL and NoSQL databases. SQL is a -specific language for organizing data in relational database management systems, while NoSQL is a non-relational way to manage data. NoSQL databases can store and recover data in any format if the method isn’t relational.
2. Data Warehouses and Data Lakes
Experienced Data Engineers create comprehensive solutions for managing data as smoothly and effectively as possible. Their primary responsibility is to manage the volume, speed and type of enormous data sets from new and unstructured sources. After extracting data from different sources, your hired data engineers must move and store the information in a data warehouse or lake. Data warehouses store structured data, while data lakes work with any kind of information, including streaming and unstructured data.
Your data engineering team should also have knowledge of how to:
- Establish a cloud-based data warehouse;
- Combine different data types in data warehouses and lakes;
- Optimize data warehouse and lake connections for efficiency and effectiveness.
3. Strong Data Expertise
Designed ETL solutions enable you to extract, collect, transform, and consolidate data in an automated way. As a result, you can take all-important management decisions more quickly than your competitors. So, a well-designed ETL system delivers data ready to optimize costs and find growth opportunities.
