Programming Languages For Data Engineers

By | April 18, 2023

Programming Languages For Data Engineers – There is an ongoing debate about what is the right programming model for Data Engineering. There are three approaches: Python, SQL++, and Visual=Code. That

Is a new approach that is being worked on to address the challenges we are seeing in the field, but there is no consensus on the right approach yet.

In this blog, we will articulate the essential complexities of operations seen in Data Engineering, and the best fit for each approach. By the end of this blog, you’ll have a structured framework for articulating which approach is best for your team (perhaps starting with an implicit understanding of the concept). The following describes the various user groups and operations we commonly encounter with our customers.

Data Engineering or ETL has an essential complexity that includes some SQL operations and some non-SQL operations. Below are some common operations for the basics of Data Engineering operations

SQL operations are the backbone of Data Engineering operations, whether you are writing code in SQL, writing DataFrame code in Python, or doing Visual Dataflow programming.

SQL is a great solution that anyone can use, but there are many operations that are common in data engineering but are not covered by pure SQL. As complexity increases, SQL also becomes more and more difficult to understand and maintain.

SQL starts to get complex pretty fast. There are CTAS, table functions, correlated subqueries – but let’s start with a fairly common operation – a basic SCD2 join:

SCD2 join is a slowly changing dimensional merge where the operational database has fields like address which don’t change very often, so in your analytical database keep a history of various addresses and dates (from-date and to-date) representing the length of time this item was active, along with flags to mark the first and last lines in the chain. This can be the same for analytics on how long a home delivery order has been ordered, or is on its way.

Here is sample code for that. This is clearly SQL that shouldn’t be written by hand. This example uses the Dataframe API, but can be written as an SQL string. This shows an example where SQL is too low an abstraction.

While it is agreed that these operations should be created, there are several ways to create coders, macros, and functions. The SQL++ DBT approach provides some basic constructs (macros) to try and handle this operation (datespine, snapshot for scd2). DBT also brings software engineering practices to SQL and is appreciated by users for it.

Now there are many operations in Data Engineering for which SQL is not a proper abstraction and you should use a programming language instead. There are several use cases here. Our customers need to perform operations that need to be done row-by-line and across rows. Here are some examples of operations

Data Engineer Vs Data Analyst

SQL has always accepted that this is not the right paradigm for these operations and provides many mechanisms for calling non-SQL code, such as user-defined functions, user-defined aggregate functions, and table functions covering the full spectrum of use cases. of the most detailed scope. call external code line by line – pass entire table to code and receive new table back.

Writing code in Python can capture these use cases, but only a small percentage of users in an organization can produce standard, high-quality code, and productivity is always low.

Templates can encode a common set of patterns – standardized practices for different parts of the ecosystem. We’ve looked at the default ingestion templates for pipelines from several similar source systems that include best practices such as verifying that the correct number of rows have been executed, which is required in a financial environment.

As you can see with the previous approach, a lot of users are left out, or a lot of use cases are left out, which is very limiting in scope.

At us, we have thought from the start on what might be the best approach to handle all data engineering activities and empower all users at the same time. Here’s our approach:

All users need to be able to use any type of transformation and be able to build any data engineering workflow, so we created an interface where all usage is in SQL – but your operations generate a mix of SQL and non-SQL code depending on the operation.

In your team you can have multiple Gem Builders (or you can request one). You can write the code you want to generate for a particular operation by writing a sample code and specifying what information the user of this gem has to fill in. When your users develop gems, high-quality code is generated in git. Here’s a quick preview of the Gem Builder:

Now that you have brought these two personas together – Gem Maker and Gem User – you have enabled your entire team to perform all the operations you need. In addition, all users can build on these data pipelines and everyone develops high-quality code in Git.

There are multiple approaches to data engineering, and as different startups look at a problem, they find the approach they believe is best suited to solving it, working hard to improve the lives of data engineers.

We have shared here the framework we use to find the best approach to provide most users with all the common elements that we find in Data Engineering. We look forward to massive innovations in the next 3-5 years to make Data Engineering more accessible and reduce the work involved.

Data analysis refers to the process of analyzing raw data to find certain trends in the data and answer questions. Data analytics covers most fields. It’s basically the science of analyzing raw data to draw conclusions from that information. In fact, it is an essential tool for analyzing surveys, polls, public opinion, etc.

It also helps researchers segment audiences based on different demographic groups and analyze attitudes and trends in each group. It is mainly used to generate more specific, accurate and actionable snapshots of public opinion. Mainly there are four types of data analysis courses. The names of the types of data analytics engineer are as follows:

Data Analytics Engineers are engineers who sit in business team interactions. They are solely responsible for bringing robust, efficient, and integrated data models and products to life. Data analytics engineers use statistics, advanced analytics, machine learning, and artificial intelligence to generate hypotheses, test, and analyze data. They use tools such as distributed systems, data pipelines, and advanced programming to clearly design and organize data.

Data Analytics in Engineering is a team effort of countless data people, analytics engineers, data analysts, data engineers and data scientists with the sole goal of producing accurate, timely and understandable datasets. Engineering Data Analysis (EDA) is an indispensable key analysis tool for industrial engineering teams to analyze processes, integrations and yields (conversion rates) effectively to increase the competitiveness of enterprises. The top programming languages ​​for Data Analytics Engineers are as follows:

What Is Data Engineering

Scala is also a powerful data science programming language. It is best suited for data science professionals. It is actually the most ideal tool for working with large data sets. A key feature of Scala is that it enables interoperability with Java, which opens up a lot of opportunities for someone working in data science. It can also be used with spark to process large amounts of silo data. This data analysis programming language also has a large number of libraries.

MATLAB is a well-known language for mathematical calculations and statistics. This allows implementing algorithms and creating user interfaces. Creating user interfaces is much easier with MATLAB because of its built-in graphs for data plotting and visualization. Knowledge of MATLAB is an economical way to easily move into deep learning because of the functionality of deep learning.

SQL stands for Structured Query Language. It is the most vital programming language for data analysis. It is used to learn to be a data analyst. Structured Query Language is important for processing structured data. It provides access to data and statistics. This feature of SQL makes it a very useful resource for it
