With the option to use tabular or multidimensional modeling, users don’t need as much specialized expertise as older relational databases required. SSAS works alongside other data visualization and BI tools such as Excel, Power BI, etc. Thanks to the OLAP cube structure, users can slice and dice their data as needed. SSAS can automatically process and parse data rather than relying on manual analysis to draw conclusions. SSAS has a lot of advantages over older methods of processing data. For example, they can’t support a role-playing relationship (associating multiple data keys with a single dimension). They are more lightweight than multidimensional and much easier to use.īut tabular models have limited functionality when compared to multidimensional SSAS. Tabular models inherit metadata from those same OLAP constructs but display them in relational constructs (model, tables, columns). For these reasons, many organizations are fazing out multidimensional SSAS. It’s also common to see multidimensional models create enormous cubes that exceed server memory. Because of this, it’s sometimes known as OLAP SSAS.īut multidimensional models are so computationally heavy that they can sometimes be challenging to use. It displays data directly as the three OLAP constructs (dimensions, measures, and cubes). Multidimensional SSAS is highly scalable and robust, making it fit for processing massive amounts of data. Businesses decide which type of SSAS to use based on the size of their data stores and the expertise of their teams. Users can view SSAS data output in two different ways: multidimensional or tabular. Cube – A data store made up of a particular combination of dimensions and measures.Measure – A categorical grouping allowing users to see numerical data points breakdowns (Time, Quantity, etc.).Dimension – A categorical grouping that enables users to view specific breakdowns of non-numerical data (Date, Location, Product, etc.).SQL Server Analysis Services uses three OLAP conventions to display data: Its drill-down and drag-and-drop features enable teams to discover powerful insights without requiring knowledge of SQL. Instead, SSAS empowers teams to ask specific questions of their data and get faster answers. Plus, they had to know SQL to search through databases in this way. Data pros had to manually parse through columns and rows to draw conclusions. At its release in the 1990s, this technology was a game changer for organizations.īefore SSAS, there were only two-dimensional options for processing data. SSAS came out of a need for processing massive amounts of data. What is SQL Server Analysis Services Used For? Plus, they can integrate with a variety of client applications. For many organizations, these semantic data models are invaluable for reporting services and data analysis. Then, users can display this compiled data in a visualization tool of some kind. It gets deployed as a database, then populated with data from all corners of the business. SQL Server Analysis Services (SSAS) is one of the technologies that seeks to solve this issue. So when it comes time to use this data for making business decisions, how do companies parse through it all? The average business has massive data stores spread across the entire organization. It enables organizations to pull data from across the organization, analyze it, then make data-driven business decisions. Microsoft SQL Server Analysis Services (SSAS) offers online analytical processing (OLAP) and data mining capabilities, enabling business users to make sense of the data stored across their data warehouses, lakes, and lakehouses.
