In response to the need to analyze large quantities of data, the field of business intelligence was created. But as the amount of data grew and requests to analyze information from payment transactions, Fitbit data, and more piled high, it seemed an impossible task. But Microsoft saved the day for businesses with its SQL Server Analysis Services (SSAS) and models, like the Power BI service and the tabular model.
SSAS helps businesses gain valuable insight through data mining and data science. The goal of SSAS is to use this data to improve customer experiences and decrease business costs.
What Is SSAS?
The two main types of SSAS are Azure and Microsoft’s SQL Server Analysis Services. They are data mining and online analytical processing (OLAP) tools that are easily accessible to companies worldwide.
These services cover reporting, integration, and analysis. Analysis services consist of two types of OLAP and data mining: multidimensional and tabular. OLAP is part of the broader category of business intelligence, which encompasses relational databases, data mining, and report writing.
SSAS creates an instant connection to backend data and has predictive analytic capabilities that use familiar applications like Microsoft Excel and SharePoint. In a nutshell, SSAS technology helps create accessible and easy to read data, to help insights from data.
Types of SSAS Models
To get a better understanding of what SSAS is, let’s look at the two main types of models we use today. These will lend some insight into what server analysis services are and the principal differences between the models.
The Tabular model is an in-memory table, which means that all the data is stored in the memory. It compresses this data using a technology called VertiPaq, which can store more than a terabyte of data. In Azure, you can store 400 gigabytes of data, so you can handle large data sets.
81% of participants stated they felt more confident about their tech job prospects after attending a bootcamp. Get matched to a bootcamp today.
The average bootcamp grad spent less than six months in career transition, from starting a bootcamp to finding their first job.
Tabular models can also summarize queries at fast speeds, and are organized in low detail columns and tables. The goal of this model is to make data simple to understand and to help businesses gain valuable insight.
Multidimensional Data Model
The multidimensional model predates the tabular model. In this model, all data is written to disk rather than stored in memory. This makes the multidimensional model slower. It is also not available on Azure. This model works by building complex cubes of data that can be used to store and locate data.
Although it is a slower and more complex process, it does have some functions that are unavailable in the tabular model.
SSAS Terms Explained
Here are some examples of typical terms that are used when discussing SSAS. Read through these so you can get a basic understanding of the systems before beginning a course in SSAS.
- Data warehouse. In computing, a data warehouse is a system used for reporting and analyzing data. Think of it as a virtual warehouse filled with information.
- Data marts. Next, you have data marts, which are like little data markets. Each data mart deals with a specific subject, so although the data contained in them is limited, it’s quicker to build these than it is to build a data warehouse.
- Named queries. A named query is usually represented as a table. You can specify an SQL expression in a named query to select rows and columns from tables in one or more data sources.
- MDX queries. MDX stands for MultiDimensional eXpressionsis a query language used to obtain data from multidimensional models.
- Data sources. A data source views where a piece of data originated from.
Once you are familiar with computer programming and data, you can easily learn SSAS through online tutorials or courses. There are also plenty of books and resources out there for students who want to become SSAS pros. Read on to see our courses section to get started learning.
How Long Does It Take to Learn SSAS?
Depending on your programming background and your awareness of SSAS, it could take you anywhere from 14 hours to 14 months to learn. If you have zero programming and data skills, it could take longer.
How to Learn SSAS: Step-by-Step
Here is a beginner’s guide on how to gain the necessary skills to learn how to analyze data with SSAS.
- Career Karma matches you with top tech bootcamps
- Get exclusive scholarships and prep courses
- Learn programming languages. Studying R and Python is a great place to start. Then, move toward learning SSAS specific languages like DAX, MDX, and TSQL. These are not programming languages, but are languages specific to data queries that are essential to learn.
- Explore resources. Then, begin looking at online resources from Microsoft on SSAS, or read some texts so that you can get a better understanding.
- Take SSAS training. You can start taking online courses for free and then study to gain a certification in SSAS. Once you are certified, you can begin working on data mining projects.
- Practice data analysis software. Practice will make you a great data-miner. Start practicing data analysis to learn about the different types of software so that you are comfortable with all kinds of data analysis tools by the time you are employed. Try out Power BI, which comes with a free trial, and when you are more comfortable, you can start to work with Azure.
