An Informative Guide To Building A Company Data Warehouse

  • Written by

Data warehouses are databases specifically designed to store and analyze large amounts of data. It allows businesses to gain insights from their collected data using advanced analytics, reporting, and visualizations. Building a company's warehouse requires careful planning, budgeting, and execution. Here is a guide to getting started.

Define Business Goals And Objectives

The goals and objectives of the warehouse should be clearly defined before any development begins. Business users need to understand why the warehouse is being built and what it will do for their business. It's important to identify what specific metrics are needed, how they will be used, and how data will be stored, retrieved, and analyzed.

This defines what types of data need to be collected, analyzed, and presented to gain meaningful insights.

Create A Data Model

A data model refers to the structure of the warehouse, including the relationships between different pieces of information. Creating a model that reflects the user's needs and allows easy access to relevant data is important.

This includes defining which tables will be needed, what fields each table should contain, and how these tables will be linked together.

Testing the model to ensure it meets performance and scalability requirements is important. This may include running simulations or conducting user studies.

A database platform is based on the types of data being collected and how they will be used. The most common choice is a relational database such as MySQL or Oracle, but other options are available such as non-relational databases like MongoDB or NoSQL.

The platform chosen should be able to handle the data volumes, provide solid performance and scalability, and offer security features to protect sensitive information.

Design A Storage Strategy

A storage strategy refers to how the data will be stored and accessed. This includes selecting hardware such as servers, disks, and networking components.

Once the data model is complete, choose a database platform that can accommodate your organization's needs. Popular platforms include Microsoft SQL Server, Oracle Database, and Amazon Redshift.

Evaluating each option in terms of its cost, scalability, and ease of use is important. Additionally, consider whether the platform offers data compression or encryption features.

Assess Data Sources

This involves assessing the current data sources in terms of type, format, and accuracy. It also includes determining how often the data needs to be updated and identifying any necessary adjustments or clean-up.

Building Of The Data Warehouses

This includes designing and building a schema that defines how data will be stored in the database. It involves creating database tables, views, and other objects. Implementing efficient data-loading processes for importing data from external sources is important.

The architecture of the data warehouse is based on the data sources identified in step one. It should include assessing the hardware, software, and network components needed to support the operations. This includes establishing a database management system and data integration tools.

The project requires professional services such as system design, development, and testing. This is necessary to ensure that the warehouse meets performance, security, and compliance requirements.


It's important to ensure that the warehouse is secure and compliant with relevant regulations or standards. This includes understanding the organization's privacy policies, developing security protocols, and implementing measures to protect data from unauthorized access or misuse.

Security is essential when protecting sensitive company information stored in a warehouse. This includes setting up user roles and permissions and defining encryption policies and data access control.

Test & Optimize

Testing includes running simulations, conducting user studies, and optimizing the queries to ensure that they perform as expected. Any issues should be addressed and resolved before going live.


This involves migrating existing data into the new system and setting up the necessary processes for ongoing maintenance. Once launched, users should be able to efficiently access and query the information they need. While launching, regular monitoring should be done to identify any errors or other issues.

Monitor, Maintain, and Improve

Data warehouses should be regularly monitored to ensure that they perform as expected. This includes reviewing performance metrics, conducting regular backups, and troubleshooting any potential problems.

Additionally, improvements should be made on an ongoing basis to optimize the system for better performance and scalability. Regular backups should also be taken to ensure that data is not lost in an unforeseen disaster. Ensure that security measures remain in place.

Consider using automated processes such as scheduled backups or regular maintenance tasks.

These steps will help create well-designed data warehouses that meet your organization's needs and provide valuable insights. With this foundation and experts at your doorstep, you can move forward with more advanced analytics and data-driven decisions.
