What does a database analyst do?

Nowadays, data is stored and utilised wherever we look. As a result, the role of a database analyst is more important than ever. Companies rely on database analysts to manage, organise, and make sense of all the data they collect. These professionals design and maintain databases, ensuring that data is accurate and easy to access. They also work to improve how databases perform, making sure they run smoothly and efficiently. By turning raw data into useful information, database analysts help businesses make better decisions and stay competitive. 

In this blog, we’ll explore what database analysts do, the skills they need, and the tools they use to succeed in their jobs.

What is data analysis?

Data analysis is the process of examining, cleaning, transforming, and modelling data to discover useful information, draw conclusions, and support decision-making. It involves several key steps:

• Data Collection: Gathering data from various sources, such as surveys, databases, or sensors.
• Data Cleaning: Removing errors and inconsistencies to ensure the data is accurate and reliable.
• Data Transformation: Converting data into a format suitable for analysis, which may include aggregating or normalising data.
• Data Modeling: Applying statistical or machine learning techniques to identify patterns, trends, and relationships in the data.
• Data Visualisation: Creating charts and graphs to make the data easier to understand and interpret.

Data analysis helps organisations make informed decisions by turning raw data into actionable insights. It is used in many fields, including business, healthcare, finance, and the social sciences, to improve operations, forecast trends, and understand complex problems.
