With the growing scope of modern-day business, you can pull massive amounts of multidimensional data from all aspects of your business. But while it’s great to have so much information available, it can take time to organize and glean insights from your data extractions, much less move forward with decision-making. Show
A data warehouse decision support system (DSS) can help you make sense of that data in time to act. What exactly are DSS and data warehouses? We’ll take a look at the basics in this guide. What is a decision support system (DSS)?DSS helps businesses make sense of data so they can undergo more informed management decision-making. Essentially, any system that provides clarity about data can be considered a DSS. That includes GPS route planners like Google Maps or Waze, which evaluate multiple routes and traffic conditions to find you the best route between points A and B. In healthcare, a doctor might use a computerized DSS to diagnose and prescribe medication for a patient. Another example would be a bank using data from past experiences to increase their chances of detecting fraud. What is a decision support system used for?A DSS can be used in several ways:
Characteristics of a decision support systemDSS frameworks typically consist of three main components or characteristics:
What is a data warehouse?A data warehouse is a collection of multidimensional, organization-wide data, typically used in business decision-making. Data warehouse toolkits for building out these large repositories generally use one of two architectures. Inmon Method:

Data warehouses and decision supportData warehouses are handy for making big-picture decision-making since they pull data from all different sources, siloes, or applications within a business. The four stages of data warehousingData warehouse development typically involves the following steps and requirements:
Data warehouse vs. databaseThough they rely on similar relational database technologies, data warehouses are not the same as databases. Database systems are used for processing day-to-day transactions, such as sending a text or booking a ticket online. This is also known as online transaction processing (OLTP). Databases are good for storing information about and quickly looking up specific transactions. Meanwhile, data warehouses are used to analyze transactions from multiple data sources. This type of online analytical processing, or OLAP technology, is used, for example, in data mining, as well as forward-looking business intelligence functions like budgeting and forecast planning. How data warehouses and decisions support systems (DSS) work togetherThink of a data warehouse DSS like a buffet. If a data warehouse is the collection of raw ingredients, then a DSS consists of the oven and other cooking tools engineers can use to manipulate the ingredients. If you know what you want to cook and use your DSS to cook up data in the right way, end users can decide which dishes look best to them and their businesses. What is the difference between a DSS and a data warehouse?A decision support system (DSS) is a system—specifically, an interactive information system—built on top of a data warehouse to make it easy to query or pull information from data. What are the advantages of a data warehouse decision support system?Data warehouse DSS benefit organizations in many ways:
