Introduction of SSAS Training:
SSAS Training by Global Online Trainings will give you the ability to understand that SSAS stands for SQL Server Analysis Service and it is the tool or service provided by Microsoft using which you can create a database that acts as an OLAP database. The OLAP database is a database that is used for various dimensions. The SQL Server Analysis Service Online Training is a database engine that provides analysis services in various dimensions. The three dimensional systems are usually called as cubes and cubes are the three-dimensional models that store data from one or more sources. SSAS Training is a multi-dimensional OLAP server as well as an analytics engine that allows you to slice and dice large volumes of data. The data can be viewed through browser tools such as Excel, more tools like sequel reporting services and also acts as a database server which provides enterprise level of security service.
OLAP database is stored in SSAS server and it is the platform for data analysis and enterprise reporting it provides two core services i.e.
- OLAP Database, the OLAP Database multi-dimensional where you can create a multi-dimensional object called queue and that Database can be used for data analysis.
- Data Mining, its analysis to find the trends and patterns in data.
Analysis service provides you Unified Dimensional model and it’s a logical model which can take the data from directly from the database or data warehouse.

SSAS TRAINING Course Content
Overview of SSAS Training:
OLAP means Online Analytical Processing by SSAS Training and it is an approach for analyzing data from multiple perspectives as well as utilizes components called dimensions, measures, and cubes. Cube is the end result of data modeling and can hold data, collect data and calculate data. Cubes will be made of dimensions and dimensions are the list of related items such as products, time or regions by SQL Server Analysis Service Online Training with training videos and course materials. These dimensions can be combined into cubes.
- The OLAP databases are stored in SSAS server and it is the framework that is used to analyze the data and reports that generated at an enterprise level.
- The SSAS Training provides the ability to create a database as OLAP and detect the latest trends in the data as same as data mining.
- It also acts as a database server which comes with the capability, reliability, scalability and higher security to provide enterprise level of service.
- The SSAS Training database is a place where you create multidimensional objects which are known as cubes and that database can be used for analysis.
- The analysis service provides the integrated dimensional representation. This representation is a logical model which can take data either directly from the OLTP database or from the data warehouse.
- The UDM component of SSAS known as the Unified Dimensional Model which can be defined as the part of the concept of analysis services and used to represent the physical databases such as OLTP or other databases stored in the data warehouse. Basically, you can create the cube by taking input from more than one data sources so data source can be more than one.
- The Unified model of SSAS Training helps to customize the system so any kind of client application can use the data without creating the individual model for both associated and multidimensional database.
- The MSBI Training by Global Online Trainings will explain to you that Business intelligence is all about data and data which are used to make profits or money. The MSBI is a tool that takes the data and converts it into the Understandable format.
SSAS Training with Cubes:
SSAS Training Cubes are models that consist of various types of information from various sources. In ETL, it takes data from multiple sources and brings them together as typically store those data in a star schema a relational data warehouse and that becomes the bases of the cubes. Cubes take data and store that data as well as can store the aggregated values or just aggregations. These values are the sums of the base data at various levels which are calculated and stored ahead of time so that when users ask for them then they are returned instantaneously.
In SSAS Training, there will be other items in the analysis services of cubes such as calculations, KPIs or key performance indicators, translation if you want to do multilingual cubes and perspectives. The SSAS is a tool used to develop cubes and a cube is a multi-structural object which is used for different analytics in a multidimensional way. SSAS includes three storage models which are:
- MOLAP: MOLAP means multidimensional OLAP. It is the default model in analysis services. It stores aggregations and all the data from the relational data warehouse in a new set of binary files. So they are completely separate from the relational warehouse.
- ROLAP: ROLAP means Relational OLAP. It is kind of the opposite approach. It stores aggregations in indexed views in the relational database. So it builds these new indexed views and stores them in the database. In addition, it leaves the dimension data and fact data.
- HOLAP: HOLAP means Hybrid OLAP. It is a combination of ROLAP and MOLAP. It leaves the dimension and fact data in the relational database.
SSAS Training Architecture:
The SSAS Training is one of the analysis platforms in the technology world which can be used for creating and managing the analysis database. This analysis database internally contains the cubes or tabular models and one or more cubes can be present in the analysis database. The SSAS database is a kind of an RDMS database which helps us to store the data in a compressed manner and when you create queries on the top of the analysis database then the queries will run in a fast manner.
- The architectural view of SSAS Training is based on the three-tier architecture where it consists of RDBMS, SSAS and the client.
- We also Provide SQL Server Analysis Service Online Training with training videos and course materials.
- The data from the data warehouse can be pulled with the help of ETL tool in the RDBMS and also pulled from RDBMS to the SSAS cubes with the help of the analysis services projects.
- So these analysis projects will help us to create an analysis database and once the analysis database is ready so it can be used for many purposes in many ways.
- The user can query directly on the top of the analytical database or can use this database in any reporting platform such as SSRS, Cognos or Tableau. The user can also directly write the MDX queries or DAX queries on the top of the analytical database.
- The SSAS developer with SSAS Training does the cube design and scripting as well as MDX queries, processing, configuration, and deployment. The developer also knows how to backup the cubes and how to perform troubleshooting and implementing the security in the SSAS.
- SSAS MDX stands for Multi-Dimensional Expression and It is not like an OLTP database which is a two-dimensional database and you have to write normal queries to retrieve the data in SQL Server Analysis Service Online Training with training videos and course materials.
- In terms of the cube, when you create, process and deploy the cube then the processes data is going to be stored in the multidimensional database where you have to write multi-dimensional expressions because it is multidimensional means it may have rows, columns and lots of dimensions. The SSAS Training MDX queries support maximum 127 levels and after fifth level name will not be displayed.
- The SSRS Training helps to understand that SSRS is a tool or reporting service provided by Microsoft using which you can create multidimensional or OLAP cubes. It provides scalability, reliability and secure database server. It is the tool which is responsible for performing data analysis and reporting service.
SSAS Training for Creation of cubes:
Once the data warehouse is ready then you can create a cube. To create a cube in SSAS Training there are few steps that need to be followed:
- The first step is to create an SSAS project and to do this go to all programs then select SQL server any version then go to file and click on the new project. Choose the analysis services multidimensional model and give the appropriate name for the project then click ok.
- The second step is to select the data source and to do this go to Solution Explorer then right click on the data source and select new data source option. After that give the server name and database name then fulfill the required information in order to connect the database to the project then click ok. The database can also be modified with SQL Server Analysis Service Online Training with training videos and course materials.
- Now the third step of SSAS Training is to create a data source view and to do this select data source view and click on add new data source view option. Click next then click the data source and select the table as you required. The data source is used to filter the table as well as the columns can be modified along with the new relationships along with SQL Server Analysis Service Online Training with training videos and course materials.
- After creating a data view the next step will be building a cube and when you create a cube the dimensions will be added automatically. To do this go to solution explorer then right click on the cube and select new cube then select the required dimensions and other options and select ok.
- When the cube is created then the next step will be processing and be deploying the cube. After getting the data the cube will process the data and will store those all aggregated into the database.
- The SSIS Training will help to achieve the main goal of SSIS which is basically collecting the data from different sources and consolidating or gathering at once inter location so we can analyze the data. The SSIS is used for three important processes which are Extraction, Transformation, and Loading.
SSAS Multidimensional vs. Tabular modeling:
Before creating a project you have to decide which model is suitable for your project and to decide that SSAS Training will help you have to know what are the features and advantages we have in the multidimensional model and tabular model.
- The size of the database is the most important factor in SSAS Training which will let you choose the appropriate and suitable model. If the database size is in terabytes up to 24 terabytes then you can go with multidimensional model and if the database size in gigabytes means up to 1 terabyte then you can go with the tabular model in SQL Server Analysis Service Online Training with training videos and course materials.
- If ever the database is greater than one terabyte then you have to choose the multidimensional model. The reason is that the tabular model is an in-memory and multidimensional model is not an in-memory model.
- In the hardware resources point of view, the multidimensional uses the memory, CPU and disk input-output whereas the tabular model uses only memory and CPU by SSAS Training.
- The analysis services stores the data on the disk so in the multidimensional model, every time the reporting required MDX queries to access the data from the disk. But in a tabular model input-output process is not required means any need to write MDX queries and only DAX queries are required.
- In the term of query performance in SSAS Training, both are fast but the language is difficult to learn and to write. The model complexity is very complicated in the multidimensional objects whereas in the tabular model the complexity became easier by SQL Server Analysis Service Online Training with training videos and course materials.
- In multidimensional, you can create the security in the low level and cell level but in the tabular model, you can only create the row level security by SSAS Training.
- In terms of development effort, the multidimensional model comes with the medium to high effort whereas the tabular model consists of fewer efforts compare to multidimensional model because it involves creating the schema, dimensions, relationship etc.
- The SSAS Training provides the ability to create a database as OLAP and detect the latest trends in the data as same as data mining
