As the world is rapidly moving towards digitalization, users are now
generating massive amounts of data. Therefore, companies must utilize new
tools and technologies to help them manage, organize, and use the data in the
best possible manner. So, how do they do that?
One of the ways is through leveraging robust programming languages like SQL.
According to Statista, SQL is one of the most used programming languages globally. In recent
times, we have seen a high influx of SQL jobs coming into the market.
But, to benefit from the new opportunities in the market, it is best to know
about the skills and features that an SQL engineer should have. So, to help
out, we’ll discuss the top 10 features to help you become a great SQL
Top Features SQL Engineers Should Know to Stand Out
Learning these skills isn’t an overnight thing. It requires you to go through
SQL training, along with regular practice so you can master them. With training and
proper practice, you can get a better grasp over the top features that can
help an SQL engineer to perform their duties efficiently.
1. Data Analysis
One of the most important skills an SQL engineer needs to have is conducting
data analysis. It can play a crucial role to an organization in their
The best thing about SQL is that it can help companies organize and manage
large and different types of data effectively. Therefore, data analysis skills
can help an SQL engineer to understand the target audience’s behaviors and
2. Views in SQL
Views refer to the virtual table that show data that are from other
tables. Simply put, they are SQL queries that include some or all the rows
from a table.
SQL Views play an important role in enhancing the database’s security by only
displaying the relevant data to authorized users. It can display data for
either a single table or multiple tables. These views allow users to see and
change only what they need and nothing else.
3. Grasp Over PHP
While it might not be a part of your SQL training courses, learning PHP can
indirectly help you become a better SQL engineer. Most developers use PHP to
create a website and SQL for the interaction of data.
By familiarizing yourself with both these languages, you can understand how a
website and the data on it work with each other. So, by learning PHP, you’ll
have a better idea of a website’s functions.
4. SQL Joins skills
The SQL engineers, use the SQL Joins clauses to merge various data sets via
the values that are the same in every set. So, understanding them will help
you combine data from various tables.
As a result, it will be less complex for you to analyze different data sets
that need a combination. Moreover, understanding the Joins clauses also helps
you speed up the process to execute queries and merge data.
5. Learning About Tables and Indexes
Tables and indexes are an integral part of the SQL and they significantly
impact the speed of query execution. By learning the purpose of tables and
indexes, you can easily make use of them for your programming efforts.
Poor indexing can negatively impact performance. So, SQL engineers need to
impose order into the correct tables so the index can work without any
6. The Purpose of Temporary Tables in SQL
Temporary tables are also another amazing feature that every SQL engineer
needs to know about. It allows you to store the data for a short or temporary
period and can assist you with CRUD (Create, Read, Update, and Delete) and
different other processes with the standard
One of the vital things to know about the temporary tables is that they will
cease to exist once the current client session ends. Nevertheless, it is an
optimal feature that you can learn during your SQL training.
7. Execution skills
Execution skills allow SQL engineers to get a better idea of the query’s
efficiency. This way, they identify and troubleshoot the queries that are not
performing up to the standard or are dysfunctional.
As an SQL engineer, having a sound knowledge of execution skills will allow
you to enhance and sustain a database’s query performance. Consequently, you
can assist companies in preventing any issues relating to data performance.
Proper training through SQL courses can help you deliver relevant skills.
8. OLAP Skills
OLAP stands for Online Analytical Processing and it refers to a kind of
database that can perform that analysis in a much more efficient and quick
manner. It can assist you with complex data-based calculations, making it an
important feature that SQL engineers should have.
Attaining this skill can help you land SQL jobs in London and various other
cities, but it would take time for you to master it. Also, an important thing
to note is that data and technology are rapidly evolving. Therefore, you would
have to constantly update and relearn OLAP skills.
9. Database Management
Database management is a critical skill for SQL engineers that will ensure
your organization have a data backup. Programmers can pick either one of the
four options for data backup, according to their needs:
- Transactional log backup
- Tail log
- Full backup
rising number of data breaches
globally is a major concern for many businesses. It makes it more than
necessary for businesses to have a data backup in case their initial database
10. Understanding of How to Manage Database Architecture
Lastly, when you have a comprehensive idea of basic SQL skills, you might want
to move on to the next step of managing the entire database architecture.
Windows, PHP, MySQL, and Apache, are a stack of software that helps you speed
up your process when you create and manage the website. So, having a
comprehensive idea about it can help you manage the database architecture.
Understanding and learning the skills through SQL courses UK will allow you to
get a competitive edge in the job market. You can land amazing opportunities
available for SQL engineers in no time.
