Data Engineering: Do’s and Don’ts

by Lee Mark

Data engineering is creating and implementing information systems that gather, store, and analyze large amounts of data. The market is vast and spans several industries. Organizations have access to enormous quantities of data, and the information has to be ready for use by data scientists and analysts when it reaches them.

Here we have an example of The Oakland Group that offers a wide range of analytical, procedural, and governance services. They are known for their work in data strategy and governance. Specific data platforms, engineering, and cloud advanced analysis, and artificial intelligence, higher-quality and better operational performance are the specialization of a sound data engineer.

However, a data engineer in any organization must remember to follow some dos and don’ts of data engineering.

What is the job of a Data Engineer?

Information scientists and business analysts need data engineers to create systems that transform raw data into useable information. Their final objective is to provide companies with data to utilize to assess and improve their operations.

Following are some basic tasks of a data engineer:

  • To achieve the business objectives, gather data sets.
  • Write algorithms that convert data into usable insights.
  • Construct, carry out, and manage database pipeline designs.
  • Work with management to grasp the company’s goals.
  • Create innovative ways to define and measure data accuracy.
  • Make sure data governance and security rules are followed.

The Role of Data Engineer

The focus of data engineering is on data collection and preparation for data scientists and analysts. The primary roles of a data engineer are:

  • Generalist- Small teams of data engineers who specialize in end-to-end data collecting, input, and processing often work on projects. While some data engineers are more skilled than they are, they are less knowledgeable about systems design. One who wants to become a data scientist to a data engineer would find this role suitable.
  • Database Centric- The concentration of data engineers in bigger businesses is on analytics databases, a full-time profession in which controlling the flow of data is the norm. Database-centric data engineers deal with data warehouses that span many databases and design the schemas for the tables in the warehouse.
  • Data engineers in this position tend to work in a mid-sized data analytics team on more complex data science projects that span several platforms. Larger businesses and midsize businesses are both more likely to require this function.

Dos and Don’ts of Data Engineering

Data engineering contains some dos and don’ts, which will be effective for data engineers following these.

  1. Technical abilities

You’ll need technical abilities to succeed in data engineering. A bachelor’s degree and years of experience in corporate data analytics may usually advance your career. A technical degree, data consultancy, or junior data engineering employment can help new engineers succeed. You will need to learn to code in languages like Python and Scala. These tools automate most of the ETL process. Even with these easy-to-use tools, data engineering may be tedious. It requires repeated tasks, including data entry into tables and a sharp eye for mistakes. It takes someone who will persevere in all areas where automation fails.

  1. Influence of Automation

Also, many data engineers are worried about automation’s effect on the future of data engineering. The prospect of wholly automated industries and the sudden learning of new skills and responsibilities may be unsettling. Many in this area fear becoming outdated in their employment. For some, the professional path will never die since every database requires human monitoring.

  1. Online Coding services

Many opportunities exist for those who wish to work in data science. You might be tempted to hire a consultant or use an online coding service like Python to help. They recruit, train, and place new programmers. You can use Python services anywhere. With the social isolation of a classroom, it isn’t easy to focus on education. Then share your programming knowledge with the community online. Even if you are starting, you will meet your level. So, you’re a whiz at tech and want to polish your skills, then feel free to explore Python for your learning needs if you have a specific interest in a topic.

Difference between a Data Engineer and Data Scientist

In previous years, firms believed they could evade having Data Engineers take on the responsibilities of Data Scientists. Data scientists also offered to be able to undertake the duties of a data engineer. Because of the quantity and velocity of data available today, the Data Scientist and Data Engineer are different jobs, but there is considerable overlap between them.

Business intelligence experts focus on sophisticated analyses performed on data held in a company’s databases. Data engineers have a hand in designing, administering, and optimizing data flow throughout the organization’s databases. Data scientists are expected to be well-versed in arithmetic and statistics, R, algorithms, and machine learning methods. SQL, MySQL, NoSQL, cloud architectures, and agile and scrum methodologies will be of more familiarity to data engineers.

Skills required for Data Engineering

Your resume skills may affect your salary negotiations, sometimes increasing your salary by 10 or 15 percent. PayScale shows that data engineering skills such as data modeling, data visualization, and data mining correlate with a notable increase in salaries. Such as:

  • Scala: 17%
  • Data warehouse: 14%
  • Data modeling: 12%
  • Apache Spark: 16%
  • Apache Hadoop: 11%
  • Amazon Web Services (AWS): 10%
  • Java: 13%
  • ETL (extra, transform, load): 7%
  • Linux: 11%
  • Software development: 2 %
  • Big data analytics: 6%

To Conclude

The data engineering profession covers a broad spectrum of technical competencies relevant to various data science professions. Two of the most common positions, data scientists and data engineers, fall under the “data” category. As the world of data increases, so makes the demand for professionals in these disciplines. Is data engineering a good choice for you despite the high income and great opportunities?

It is commonly said that most of the effort spent on analytics is invested in data engineering and data organization. The Oakland Group is an organization that does not limit itself to one area of technology but is involved in the full spectrum of technological innovation. Therefore, you may become a successful data engineer by getting an idea from this firm, and some basic do’s and don’ts of data engineering.
