SASStatistical analysis system

SAS pronounced as Saas. Is a software suite developed by sas institute for advance

analysis, Business Intelligence, predictive analysis, data management which help

organization to operate effectively in the competitive and

changing business conditions.

• In addition it helps in improving performance, profitability and decisions.

• SAS provides a Enterprise software named, SAS Intelligence Platform which consist of various

aspects i.e. Applications exist on Multiple machines.

SAS Intelligence platform is a JAVA application. SAS IP uses JDBC (JAVA DATA BASED CONNECTION)

technology from oracle corporations.

SAS_Architecture

• Client tier.• Web tier.• Server tier.• Data tier.

• Client tier:-Client tier is where the application is installed on a machine, where user sitting.

• Types of client application are:-• Java application.• Windows application.• Web browser application.

• Web tier:- Web tier is where web application resides and executes.

• Infrastructure that supports the execution of the web browser application are:-

• Java application server.• Java SDK(Software development Kit).• Web DAV (Distributed Authoring &

Versioning)server

• Server Tier:-Server tier is one or more machines where the SAS server are installed and accessed by BI applications.

• The different types of server are:-• Metadata server.• Workspace server.• Stored process server.• OLAP server.

• Metadata server:- META data is a prefix in information technology usually means underlying definition or description.

• Meta data is data about data.• Can be created manually or automated.• Eg-size of a file , description of the file.

• Workspace server:- The SAS workspace server is a single user server.

• There are two categories of server configuration:-

• Default server configuration.• Pooled server configuration.

• Stored processes server:-This server runs under a single shared user identity and is a single process shared by many clients.

• A stored processes is a SAS program that is stored on a server and described by metadata.

• Stored processes can create new dataset, files and reports output in a variety of formats.

Note:-I will try to explain SAS programs in next session of SAS tutorials.

• OLAP server:- SAS OLAP server is a standard complaint OLAP data source that retrieves result for MDX queries.

• It quickly delivers summarized data to BI application in a format that enables processing , reporting and lowers the burden on by simplifying adhoc reporting and data summaries.

• Data tier:- The data tier contains the enterprise data sources:-

• SAS data sets.• RDBMS tables.• OLAP cubes.• SAS SPD server files.• ERP data structures.

Desktop applications.• SAS Intelligence platform consist of Applications-

• 1.SAS INFORMATION MAP STUDIO. (IMPS)

• 2.SAS OLAP CUBE STUDIO.(OLAP)

• 3.SAS DATA INTEGRATION STUDIO. (ETL)

• 4.SAS ADD_IN_FOR_MICROSOFT.

• 5.SAS ENTERPRISE GUIDE. (EG)

WEB Based Applications.

• 6.SAS WEB REPORT STUDIO. (WRS)

• 7.SAS INFORMATION DELIVERY PORTAL. (IDP)

• 8.SAS BI DASHBOARD.

• 9.SAS OLAP viewer for java.

Desktop based applications.

• INFORMATION MAP STUDIO:-‘”Information Map studio is used to build

information Maps, which shield for business users for the complexities of underlying data by organizing and referencing data in business terms”.

Note-Person who deals with business data are called business users.

• OLAP CUBE STUDIO:- SAS OLAP cube studio is used to create OLAP cubes.

• Cubes contains the data organized and summarized into multidimensional structure.

• Cubes are created on Detailed table(Original table) or star schema.

• Cube consist of Dimension, Level, Hierarchy.• MDX expressions are used to query against a

Cube.

• SAS DATA INTEGREATION:- SAS DI is used in ETL(Extract,Transform,load) process.

• SAS add_in_ for_Microsoft office:-Provides you the ability to hardness the power of SAS analytics and access SAS data sources.

• We use add_ins for adhoc reporting { creating for particular purpose only} to execute stored processes dynamically and embed the results in your documents , spreadsheets and slideshows.

• In general we do is,• Access and view SAS data sources.• Access and view any other data sources that is

available from your SAS server.• Analyze SAS or Excel data using analytic tasks.

• Note:- Business users are very familiar with MS office as a BI application , so its important and user friendly in use.

• SAS ENTERPRISE GUIDE:- Enterprise guide is a querying and reporting tool which is also used for conversion of source data into SAS data files.

-Provides.• An intuitive(easy to understand), visual interface.• Access the power of SAS.• Transparent access to data.• Ready to use task for analysis and reporting.• Easy exporting of data and results to other applications.• Scripting and automation.

• Note:-SAS programming ,is a sequence of steps that the user submits for execution. i.e.PROC step and DATA step.

Web based application

• Web Report studio (WRS):- WRS is a reporting application, designed for business users to view, author and share reports on Web.

• WRS is similar to Desktop application. viz. Enterprise Guide.

• Note:- there is no need to install Web applications, its zero download software. You just need to check the services are running and initialize the requried services. Eg.Tomcat,Sas services.

• Information Delivery Portal :- (IDP) Enables you to view and organize content on portal.

• Which are the pages and portlets surface all types of information, including SAS Information Maps, SAS WRS,SAS stored processes.

• Portlet is a rectangular display components of the portal in which content and links to content are displayed.

• SAS BI Dashboard:-BI dashboard is used for creating , maintaining and viewing dashboard.

• Is surfaced as portlet in the SAS IDP.• SAS BI dashboard is an application that represents the

latest evolution of Dashboarding using SAS. It enables the rapid creation and deployment of dashboards that display data from a wide variety of data sources and system.

• Dashboards is a way to represent numbers in easily consumable , graphical form to display key metrics within an organization.

• SAS OLAP viewer for java:- used for viewing SAS OLAP cubes. Provides an easy-to-use interface from which you can select a data source , view the data , and customize your view.
