There are different possibilities for storing data depending on your needs. While some are starting with a simple data warehouse, others are reaching the capacity of utilising a data mesh. We will define some concepts that will help understand the different storage options and how it can benefit your business.

Data warehouse is a first step in storing data and it is known to be a good option for reporting, sustaining decision-making through quantitative and qualitative facts. In essence, a data warehouse is a consolidated and structured repository for your data assets, through ETL (extract, transform, load) data modelling principles. As a result, this method can transform the data based on predefined reporting schemas, supporting the business in various way:

However, data warehouses are limited in storing non-SQL databases and processing algorithms that require direct data access. In addition, in all ETL structures, data needs to be transported to feed the warehouse, making it impractical and compromising its overall efficiency.

Data lakes can to some extent overcome such limitations as your capabilities will be extended to much more than just reporting, by integrating raw data usage (data from images, internet, sensors, live events, etc.) The ability of storing a large amount of raw data in one single repository will deviate from the lengthy usage of multiple ETL systems. Fundamentally, using a data lake will:

When dealing with a great amount of data, it is likely that you will not need all the data stored. With improper management, a data lake can easily turn into a data swamp filled with irrelevant data while relevant data can be very poor in quality. Formatted only for operational needs and unsuitable for any sort of analysis, a data lake will not be able to keep up with processing capabilities for modelling execution.

One way to overcome this challenge is by implementing a data hub. As a strategic intermediary between producers and consumers of data, hubs allow real time data management (streaming and feeding data to applications in real time). Resulting in a boost for any data lake and rapid integration with pre-existing data warehouses through its streaming capabilities. With a data hub you manage to comprise all data warehouse and data lake advantages in one go.

Taking data storage a step further by distributing data management capabilities to different data domains, can be achieved by adopting a micro-service architecture: Data Mesh. The most intriguing part about such an architecture is its self-service infrastructure where a data engineer can focus on the logical transformation of data instead of the necessary tech. Data is discovered, explored and consumed in your data domain. So much so that it treats the data as a product, providing a federated governance model that is centrally managed.

Investing into a modern data management platform can not only provide the necessary tools to govern your data but also scale with it side by side without compromising resources or expertise. When moving from one type of data storage to another, security and corruption can pose a threat, resulting in compatibility or scalability issues. Opting for a platform that supports SQL queries can make historical data more accessible than ever. Consequently, implementing such a platform will ensure a smoother integration of your data within the desired infrastructure.
