Why Data Engineers Are in Demand and How Training Helps

Nowadays, there is are lot of data being generated by different businesses from different channels, such as social media, sensors, and customers. In order to convert this information into a readable form, it is necessary to have data engineers who can build, create, and maintain the data systems. They are the staff who are responsible for making data-driven decisions and the ones who are in demand in companies.

The Growing Demand for Data Engineers

Many reports have identified that the most rapidly growing job market is the data engineering profession, and it is also said that there is a critical shortage of qualified professionals. This is primarily because of the increase in the demand for data engineers, owing to the growth of big data, artificial intelligence, and cloud computing.

Firms from the fields of finance, health care, and technology are requiring data engineers who can support their operations in addition to searching for virtues. Due to its growing demand, numerous students are gaining interest in Data Engineer Training Online. Here are some reasons why Data Engineers are in high demand. 

• Design and create data pipeline: Data engineers are responsible for the development of the data pipeline that is used to gather, process, and store large datasets from numerous sources.

def extract_data():

    return ["data1", "data2", "data3"]

def transform_data(data):

    return [d.upper() for d in data]

def load_data(data):

    print("Loading data:", data)

raw_data = extract_data()

processed_data = transform_data(raw_data)

load_data(processed_data)

• Create data architectures: Data engineers create architectures that can be scalable for collecting, storing, and processing a massive amount of data for businesses that require data for decision making.

• Guarantee data quality and integrity: Data engineers are in charge of verifying the quality of data so that it is not only updated, complete, and coherent but also that it complies with the data quality regulations of the company.

import pandas as pd

data = {'Name': ['John', 'Sara', None], 'Age': [28, 34, 22]}

df = pd.DataFrame(data)

print(df.isnull())

Key Skills for Data Engineers

To be a successful data engineer, possessing both technical and soft skills is essential, for instance:

• Programming skills: Data engineers are supposed to know programming languages, namely Python, Java, and Scala.

• Data processing frameworks: Being acquainted with the data processing frameworks, for instance, Apache Spark, Apache Hadoop, and Apache Beam, is a matter of necessity for data engineers.

from pyspark import SparkContext

sc = SparkContext("local", "WordCount")

lines = sc.textFile("sample.txt")

counts = lines.flatMap(lambda line: line.split(" ")) \

              .map(lambda word: (word, 1)) \

              .reduceByKey(lambda a, b: a + b)

counts.saveAsTextFile("output")

• Cloud computing: A data engineer working with cloud platforms such as AWS, GCP, or Azure will certainly have an edge.

• Data storage solutions: Data engineers' work is to know the data storage solutions, with relational databases, NoSQL databases, and data warehouses being the most common ones.
