1. SQL

SQL is one of the most essential skills for data engineers. It is impossible to manage the relational database management system without adequate knowledge of SQL. For this, one must go through an extensive query list. Moreover, it is not just about memorizing the queries; you should also know how to implement them.

2. Apache Spark and Apache Hadoop

These Java-based frameworks are open-source software and enable the distributed processing of massive data collections among computer clusters. For instance, Hadoop is a distributed application platform designed to address the difficulties of managing massive data sets. It can be applied to interactive inquiries, batch processing, iterative methods, and computationally challenging issues.

Spark is a quick, in-memory data processing platform with sophisticated Python, Java, and Scala APIs. It can process data in HDFS, Hive, HBase, Cassandra, and any Hadoop InputFormat. It leverages Hadoop clusters via Spark or YARN’s standalone mode.

3. Coding

Data engineers often have to run different commands on applications and software to use technologies such as machine learning and big data. Therefore, they need to know how to program them. Hence, to become a successful data engineer, you should master the coding language. Moreover, coding is an essential requirement for a data engineer profile. Many companies look for candidates who work in C, Python, C++, Scala, or Pearl knowledge.

4. Database Designing

The process of creating database tables and schemas by specifications or business rules is known as database design. It entails selecting an object-oriented or relational design, choosing the kind of database to utilize, and figuring out which information items will be employed. It is an essential skill as it underpins the organization’s information strategy. 

A properly designed database is needed for the following:

• Storing information reliably
• Ensure reliable data output is loaded into different systems, such as BI tools. 
• Run sophisticated queries with fast loading times. 

On the other hand, a badly designed database can create multiple issues for the companies. These can be security issues, performance issues, and information integrity issues. Moreover, since the database will be poorly designed, the data or the information stored in it will also be unuseful.

5. Data-Driven Decision Making

Most importantly, you must be passionate about exploring data and making data-driven decisions. Data is a vast area, so you should always have a flair for learning something new. In addition, you should also have a passion for finding valuable insights from the data that can be helpful for businesses.

Is there a Difference Between Data Engineers and Data Scientists?

People often correlate a data engineer with a data scientist. However, they both are two different job profiles. Designing and implementing the systems and procedures that collect and process data falls within the purview of a data engineer. 

On the other hand, a data scientist is primarily involved in organizing this collected data in the architecture built by these data engineers. These data scientists also perform in-depth analyses and share valuable insights for business decisions.  

Even though they are two different opportunities, they both work hand-in-hand. Moreover, a data scientist can never get the desired outcome without a data engineer.

What is the Difference Between a Data Engineer and a Data Analyst?

Just like data engineers and data scientists are not the same, data analysts are also different. Let’s understand how.

A data analyst is responsible for analyzing data sets to gather knowledge and valuable insights. However, data engineers build and create systems to collect, validate, and prepare high-quality data. Data scientists and analysts use this data to analyze and identify trends and patterns for insights.

Why Do Companies Need Data Engineers?

According to Gartner’s predictions for 2022, 85% of data-based projects will fail to produce the expected outcomes. However, as businesses progressively increase their expenditures on data infrastructures, the forecast will probably come to pass. 

In addition, the companies may bring on specialists who can effectively utilize data. Since data engineers are the ones who will work on raw data, clean it up, polish it, and get it ready for analysis, that is why business managers search for them. Thus, there is a massive demand for data engineers.
