What Is a Time Series Database and How Does It Work?

Introduction to Time Series Analysis in Machine learning | Analytics Steps

Data is the new treasure of this online world, which requires management too. However, to manage the, especially time series data, Time Series Databases come into play. 

Time Series Database plays a crucial role in various sectors and industries, such as finance and IoT (Internet of Things). Even if you’re considering a Web Host in Singapore to buy domain and hosting, understanding Time Series Databases is essential for efficient data management in your online ventures. 

So, in this article, let’s explore what a Time Series Database is and how it works. 

What is Time Series Data? 

To understand Time Series Databases better, let’s first understand the concept of time series data. Time series data refers to a sequence of data points, measurements or events collected or recorded at intervals. These data points are arranged in order, each associated with a timestamp.   

Here are some common examples of time series data include:

  • Stock prices are recorded over time.
  • Temperature measurements are taken at intervals.
  • Website traffic statistics are collected hourly.

What Is a Time Series Database (TSDB)?

A Time Series Database (TSDB) is a uniquely designed database management system that efficiently records, monitors, measures, tracks, and analyses the time series data. A time-series db is optimised for measuring change over time. 

Unlike traditional relational databases, TSDBs can easily sort through large and complex amounts of data, making the information more accessible. 

If we talk about the Time Series Database example includes the changes to trades in a financial market, statistics collected from microservices, etc..

Key Characteristics of Time Series Databases:

  • Every data point in a Time Series Database is associated with a timestamp
  • Typically collected data at regular intervals, whether in seconds, minutes, hours, or other fixed time increments.
  • Optimised for high write throughput
  • Save storage space and improve query performance by employing data compression techniques.

How Does a Time Series Database Work?

Let us understand how the Time Series Databases operate by organising and indexing data points in an order: 

  1. Collecting Data: Time Series Databases collect data points as they are collected, and then these gathered data points will be assigned with the timestamps to maintain a chronological order.
  2. Storing Data: TSDBs store data points effectively, often using compression methods to reduce storage space requirements. They store the data in an organised manner using tables or series, each representing a specific type of time-ordered data.
  3. Creating Indexes: To enable retrieval of data, TSDBs create indexes based on timestamps and other relevant attributes. These indexes allow for querying and filtering of the stored information.
  4. Performing Queries: Users and applications can query the TSDB to retrieve data points or perform functions over a specified time range. Queries can vary from simple point lookups to operations.
  5. Retention Policies: TSDBs typically include retention policies determining how long the data is kept before being purged or archived. It helps manage storage resources. 


Understanding the concept of Time Series and time series Database will help you to record, manage and analyse the time-tagged data efficiently and effectively. 

Even if you handle web hosts in Singapore, it may help you manage the data of resources allocated to each client for different timelines and compare revenue.  

So, what you are waiting for is to understand how it works and leverage it in your business to manage your database effectively.
