Data warehouse showing databases vs datawarehouses.

When it comes to data management, there are two main options: databases and data warehouses. Both have their unique benefits and drawbacks, so it can be challenging to decide which option is best for your business. This article will discuss the differences between databases and data warehouses and help you decide which option is right for you.

What Is a Database?

A relational database is a collection of data organized in a specific way. The difference in the information inside databases vs. data warehouses is that databases are typically used to store information that needs to be accessed quickly, such as customer records or product inventory. With an OLTP (online transaction processing) database, data is organized into small, manageable pieces that users can easily access.

The Benefits of Databases

There are several benefits of using a database, including:

  • Databases are easy to use and understand: A stark difference between databases and data warehouses is their level of user-friendliness. Users can easily access and query data from a database. Whereas data warehouses, which source data from multiple locations may be initially be more difficult to understand.
  • Databases offer fast access to data: Multiple users can access a database simultaneously, and data can be quickly retrieved from a database.
  • Improved data security: With a database, you can improve your data security by controlling who has access to your data and their level of access. This helps to prevent unauthorized users from viewing or modifying your data.
  • Increased efficiency: Another big difference between databases and data warehouses is the ease of finding data. Databases can help you quickly find the information you need without sifting through mountains of data.

When To Use a Database

As more businesses move to the cloud, data storage is becoming increasingly popular. Databases are effective in handling all kinds of data, with many use cases including:

  • Customer data: Customer data can be stored in a database and quickly accessed when needed.
  • Product data: Product information, such as inventory levels and pricing, can be stored in a database for easy access.
  • Sales data: Sales data can track customer purchase history and trends.
  • Financial data: Financial data, such as invoices and transactional data, can be stored in a database.

If your business collects data from multiple sources and databases, consider using software to manage them. DreamFactory is an API management platform that helps companies integrate all of their enterprise data on a single interface. This removes the need to choose between databases and data warehouses.

What Is a Data Warehouse?

A data warehouse is a larger, more centralized repository of data. Unlike transactional databases, data warehouses are designed for online analytical processing (OLAP) rather than for transaction processing. Data warehouses and OLAP systems typically store data from multiple sources, including OLTP databases, flat files, and third-party data. Data warehouses are often used for business intelligence and decision-making purposes.

The Benefits of Data Warehouses

There are several benefits of using a data warehouse, including:

  • Improved decision making: With a data warehouse, you can easily generate reports and analytics that can help you make better business decisions.
  • Scalability: Data warehouses can scale up or down as needed, making them a good option for businesses that are growing quickly.
  • Rigid schema: A data warehouse has a rigid schema, which means data is stored in a specific way. This makes it easy to make analytical queries and generate reports.

When To Use a Data Warehouse

With data warehousing, businesses can get a single view of their big data, which can be helpful for data analysis. For companies that need to gather data from multiple sources or generate complex queries and reports, a data warehouse may be the right solution.

Businesses may need to gather data from multiple sources for many reasons, including:

  • Generating financial reports: To create financial reports, companies need to collect data from various sources, including accounting software, CRM systems, and third-party data.
  • Analyzing customer behavior: To understand customer behavior, companies need to collect data from social media, website analytics, and sales data.
  • Identifying trends: To identify trends, businesses need to gather data from multiple sources, including market research, customer surveys, and data on social media.

The Relationship Between Databases and Data Warehouses

When comparing databases and data warehouses, it’s important to note the relationship between the two entities. Databases typically aggregate data and send it to data warehouses via ETL (extract, transform, load) processes. Data warehouses store this data in a central location, where it can be easily accessed and analyzed through visualization.

While reviewing databases and data warehouses, it is important to note that they are not mutually exclusive. In fact, many businesses use both databases and data warehouses to get the most out of their data. For example, a company may use a database to store customer records and product inventory and then use a data warehouse to generate reports and analytics. 

One of the key differences when looking at databases vs. data warehouses is the type of data they hold. Data warehouses typically hold historical and current data, while databases hold live, real-time data. Depending on how often the ETL process runs, data warehouses can have data that is only a few minutes old or data that is several months old. This means that databases usually have better data integrity and are more accurate due to holding new data.

While this may seem technical or complicated for some business owners, many tools exist to help those with no coding experience. DreamFactory’s platform offers a low-code interface that allows team members to manage data without programming knowledge.

Which Data Model Is Right for Your Business

There are many factors to consider when choosing between databases and data warehouses, including:

  • The type of data you need to store: If you only need to store live, real-time data, then a database may be the right choice. If you need to store historical data, a data warehouse may be a better option.
  • The amount of information you need to store: Data warehouses can scale up or down as necessary, making them a good choice for businesses that are growing quickly and require large volumes of data.
  • Your budget: Data warehouse architecture can be more expensive than databases, so a database may be the better choice if cost is a concern.
