Our focus at DashboardFox is making report and dashboard creation simple and cost-effective for businesses (while maintaining very strong data security). A lot of our attention focuses on the front-end and data visualization or display.
However, because we query data from a database or data warehouse, it is beneficial if the data is correctly organized. When you don't have control over the database but are reporting from a vendor's application database, they are unlikely to include measures, facts, or dimensions.
As you build the semantic layer (app) in DashboardFox, you may create some of these elements to aid in report creation from the perspective of a BI report builder. As a result, knowing these words is beneficial.
In this guide, we'll look at how measures, facts, and dimensions apply to typical database warehouse concepts, as well as how you may utilize them outside of that context and solely in the process of creating reports.
Measures, Facts, and Dimensions at a Glance
When it comes to organizing and modeling data in databases and data warehousing, we frequently use the terms facts, measurements, and dimensions. However, in this context, the definitions of facts, measures, and dimensions are not exactly what you'd find in a dictionary. Let's take a look at these notions because they'll help you comprehend how DashboardFox's data warehouse cloud interprets your data.
What are the Facts?
A fact is the component of your data that shows a specific occurrence or transaction, such as the sale of a product or receiving a shipment of a specified quantity of products from a supplier, in the context of a data warehouse. Consider the statistics that would display in the data warehouse of our hypothetical corporation, Best Hats Around:
- Selling a hat for $25 on the internet.
- The existing warehouse receives a shipment of 100 hats from a supplier.
- A consumer is receiving two hats.
- Getting a $200 late payment from a customer.
- An employee is paid a salary of $15,000 per year.
Does that make sense? It's crucial to understand that a fact (such as "I sold a pair of shoes") comprises numerous measures.
What are the Measures?
A measure might be qualitative, such as a Product ID, or quantitative, such as a product's price. Following the example above, the act of selling a hat online entails several factors, including:
- It was sold at 1 p.m. the day before yesterday.
- It was purchased for $35.
- SFAF3423 is the product ID.
A measure is a name given to each of these facts about reality. Applying computations or aggregations to quantitative measures as needed for your data model is a part of data modeling. The qualitative measures can then be linked to the measure's specific properties, which are referred to as dimensions.
What are Dimensions?
Dimensions in the context of a data warehouse are pieces of information that help you comprehend and index measures in your data models. Dimensions are characteristics of a measure or data points that help contextualize a fact.
For instance, here are some of the dimensions found in our company's data warehouse, Best Hats Around:
- The hat was sold.
- Color of the hat
- Size of the hat.
- The name of the company.
- Employee's name.
- An employee's office location.
- A warehouse where a hat is kept for sale.
The distinction between facts and dimensions affects your data models and how they are represented graphically.
When Should You Use Measures, Facts, and Dimensions?
A measure can be beneficial in a variety of situations. A measure is a numerical value that indicates a business metric and is usually additive. You aren't restricted to a particular metric, either. Within a fact table, you can have numerous measures. If your fact table is used to track foreign purchases, for example, you might have measures for each sort of currency. If you're putting together a fact table for the retail industry, you'll probably want to include the following measures: cost, list price, and average sale price.
Using facts or fact tables is advantageous in various situations. Fact tables come in a variety of shapes and sizes.
The most fundamental table is a transactional table. A transactional fact table's grain is typically described as "one row per line in a transaction," for example, every line on a receipt. A transactional fact table typically stores data at the highest level of detail, resulting in many dimensions.
As the name suggests, the periodic snapshot captures a "picture of the moment," where the instant can be any defined period of time, such as a salesman's performance summary for the previous month. A periodic snapshot table is reliant on the transactional table since it requires the transactional fact table's precise data to produce the desired performance output.
Accumulating fact tables display the activities of a process with a well-defined start and end, such as order processing. It goes through a series of processes until an order is entirely processed. The associated row in the fact table is updated as actions toward fulfilling the order are accomplished.
Multiple date columns are shared in an accumulating snapshot table, each reflecting a process milestone. Because many milestone dates are unknown at the time of the row's creation, it's critical to include an entry in the corresponding date dimension that reflects an uncertain date.
Dimensions, like the previous two notions, are incredibly beneficial. When facts or fact tables are employed, dimensions should be used. The dimensions of a fact are stored in a dimension table linked to the fact table by a foreign key.
robustMuchreport in the context of a data warehouse, a is no limit to the number of dimensions that can be used, and each dimension can include one or more hierarchical relationships. There are also different dimensions that can be useful for different things, such as conformed, outrigger, role-playing, and many more.
