Comparing Build and Manage Capabilities Bouayad & Bouzoubaa 9 Selection Criteria BI Platform Strategies. BI platform Partnerships Packaging & Pricing BI databases OLAP Data Mining Interfaces Build and Manage Capabilities Bouayad & Bouzoubaa 10 Data Warehouse Databases Should support both relational and multidimensional data warehousing databases. Storage models should support the distribution of data across both. Data models should support transparent or neartransparent access to data, wherever it’s stored. Bouayad & Bouzoubaa 11 OLAP Critical business intelligence platform component. Most widely used approach to analysis. Business intelligence platforms must provide: OLAP support within their databases. OLAP functionality, interfaces to OLAP functionality. OLAP build and manage capabilities. Bouayad & Bouzoubaa 12 Data Mining. Critical to business intelligence platform capability. Platforms should include data mining functionality that offers a range of algorithms that can operate on data warehouse data. Bouayad & Bouzoubaa 13 Interfaces. BI platforms should provide open interfaces to data warehouse databases. OLAP, and data mining interfaces should comply with standards. Open, standards-based interfaces make it easier both to buy and to build applications that use the facilities of a business intelligence platform. Bouayad & Bouzoubaa 14 Build capabilities Should include the implementation of: data warehouse models, the extraction, movement, transformation, and cleansing of data from operational sources, and the initial loading and incremental updating of data warehouses according to their models. A wide range of data sources should be supported: files, and the data of popular packaged software. Transformation capabilities should be powerful and flexible. Predefined transformations should be packaged. ( & extensible through programming languages.) Bouayad & Bouzoubaa 15 Manage capabilities Should cover all platform resources—users, data, and processes. Strong and flexible prepackaged capabilities are essential. Good use should be made of visual tools. Bouayad & Bouzoubaa 16 Outline Introduction What is Business Intelligence Selection Critieria Definition. Products Comparison. 1. BI Platform Strategies.

Hyperion Essbase 6.5 Bouayad & Bouzoubaa 18 Platform Strategy Comparison Platform Partnerships Packaging & Pricing Bouayad & Bouzoubaa 19 Microsoft BI platform Based on SQL Server 2000 and Office XP. Deliver a comprehensive (all in one) business intelligence platform : Advanced data warehousing techniques Great analytic functionality Good performance and scalability across all platform components. Bouayad & Bouzoubaa 20 Microsoft BI platform Through Microsoft’s business intelligence platform: Push business intelligence to the edges of the enterprise Make business intelligence dominant within the corporation Make business intelligence more reachable for more users and more types of users Bouayad & Bouzoubaa 21 Microsoft BI platform The Microsoft formula has these key elements: Fast implementation Ease of learning and ease of use Low cost and high value Fast return on investment (ROI) Bouayad & Bouzoubaa 22 Microsoft Partnerships Ms BI Platform is built in Microsoft technology Microsoft controls all aspects of it design, development, product marketing, and support This is essential in order to provide consistency, integration, and timely technology delivery Windows OS dependent Bouayad & Bouzoubaa 23 Microsoft Partnerships Partnerships are critical to Microsoft and to its business intelligence platform. The firm currently uses partnerships to create a large base of specialized business intelligence tools and applications that supports its platform. These partnerships simplify and accelerate adoption of the platform and make the platform’s resources more easily accessible. Bouayad & Bouzoubaa 24 Microsoft Packaging and Pricing Strong selling argument of Microsoft. For the processor-based license fee of $19,999 per processor for SQL Server Enterprise Edition You get the entire business intelligence platform: OLAP / data mining / build & manage capabilities Bouayad & Bouzoubaa 25 Oracle BI platform Oracle 9i AS Object/relational database management system designed and positioned to support all types of Internet-based applications. Complete and integrated infrastructure for building BI applications. Oracle9i OLAP & Oracle9i Data Mining Features of Oracle9i Enterprise Edition. Bouayad & Bouzoubaa 26 Oracle BI platform Build and Manage functionality is provided by two toolsets: Oracle Enterprise Manager: main management framework and DBA toolset as well as the toolset for OLAP build and manage. Oracle9i Warehouse Builder: Component of Oracle Internet Developer Suite Provides capabilities for: Managing relational data warehousing resources Designing relational data warehouse models ETL (Extraction Transformation and load). OS Independent Bouayad & Bouzoubaa 27 Oracle Partnerships Do not play a major role within Oracle’s business intelligence platform. The “complete and integrated infrastructure” means that every platform component is provided by Oracle and is based on Oracle9i. Oracle’s R&D organization controls the design, development, and support of the entire platform. Bouayad & Bouzoubaa 28 Oracle Partnerships Oracle uses partnerships for business platform tools and applications. Although the firm currently competes with these partners with its own business intelligence tools and applications. Oracle’s BI platform does not include partner technology Oracle has the important advantage of control over the platform’s components, technology, and integration. Bouayad & Bouzoubaa 29 Oracle Packaging and Pricing Oracle offers little bundling. All the components its business intelligence Sum = $of95,000 platform are separately packaged and priced. Build and manage components have separately priced and packaged sub-components. O9i Enterprise Edition : $40,000 / processor. + O9i OLAP: $20,000 / processor. + O9i Data Mining: $20,000 / processor. + O Warehouse Builder: $5,000 per named user. Bouayad & Bouzoubaa 30 IBM BI platform Based on DB2 The DB2 Universal Database (UDB) provides relational data warehousing capabilities. The database also integrates basic relational data warehousing build and manage capabilities. OLAP functionality and OLAP build and manage functionality are provided by DB2 OLAP Server. Bouayad & Bouzoubaa 31 IBM BI platform DB2 OLAP Server: feature of DB2 Enterprise Server Edition that is OEMed from Hyperion and re-branded. Data mining functionality: provided by DB2 Intelligent Miner and DB2 OLAP Miner. Warehouse Manager: enhance the integrated relational build and manage functionality of DB2. DB2 OLAP Administrative Services provides OLAP build and manage capabilities. Bouayad & Bouzoubaa 32 IBM Partnerships IBM relies on a set of partners to assemble it BI platform. The most critical partnership : Hyperion Solutions. Partners also provide ETL and data cleansing The partnership with Hyperion: gave IBM OLAP capabilities instantly allows IBM to compete in an important market where it had no previous presence and where it had made no investment in R&D. Bouayad & Bouzoubaa 33 IBM Partnerships At long term: disadvantage to IBM’s business intelligence platform and to its BI customers and partners. Why? Because OLAP is more an add-on than an integral component of IBM’s BI platform. IBM has no direct control over OLAP technology, its development, and its integration within its BI platform. Given the importance of OLAP, IBM should either acquire Hyperion or develop its own OLAP. Until then, its BI platform will always be at a disadvantage. Bouayad & Bouzoubaa 34 IBM Packaging and Pricing Every component of IBM’s BI platform is separately packaged and priced Individual components offer good value, but the whole platform can be quite costly. DB2 UDB (Enterprise Server Edition V8.1 ): $25,000 per processor. ( provides the basic build and manage functionality of Data Warehouse Center) Bouayad & Bouzoubaa 35 IBM Packaging and Pricing DB2 OLAP Server: $28,000 per server + additional $1,500 fee per named user. (includes the build and manage capabilities of DB2 Administrative Services and the data mining functionality of DB2 OLAP Miner). Intelligent Miner: 3 components. $75,000 per processor for the 3. For advanced relational build and manage capabilities: DB2 Warehouse Manager : $10,600 per processor. SUM = $138,600 without external ETL and data cleansing tools Bouayad & Bouzoubaa 36 Hyperion BI Platform The technology platform for Hyperion’s performance management solutions is Essbase, its admired OLAP Server. The firm states its objective “is to be the leading global provider of business performance management solutions.” These solutions are designed to automate the business performance management process of strategy setting, modeling, planning, performance monitoring, reporting and analysis. Essbase is evolving away from a general purpose OLAP facility and toward a platform for supporting a very specific type of BI application. Bouayad & Bouzoubaa 37 Hyperion BI Platform additional platform components not offered by Hyperion are required, most significantly relational databases, data mining tools and analytic applications. Hyperion does not provide a complete business intelligence platform. Rather its Essbase product can provide the OLAP functionality within another leading comprehensive BI platform. Essbase integrates OLAP build and manage functionality. Bouayad & Bouzoubaa 38 Hyperion Partnerships Hyperion must partner in order to expand from its OLAP niche and address all BI platform requirements. IBM is Hyperion’s most important business intelligence platform partner. Hyperion also has many BI tools and applications partners that are empowered by the OLAP capabilities of Essbase. Bouayad & Bouzoubaa 39 Hyperion Packaging and Pricing Hyperion Essbase has a pricing model for with two elements: the per server fee is $28,000 / processor the per named user fee is $1,500. Essbase packaging includes: OLAP server, administrative tools, and build and manage tools. Essbase installations most commonly use relational data warehouses as the data sources for Essbase cubes. This approach requires the purchase a complete data warehousing infrastructure in addition to the Essbase, which is worth another $28,000 SUM = $56,000 Bouayad & Bouzoubaa 40 Product Comparison Platform Strategy Comparison Comparing BI databases Bouayad & Bouzoubaa 41 Comparing BI databases Microsoft SQL Server 2000 All of the Microsoft’s BI platform technologies and products are implemented as SQL Server 2000 No-charge features and are included “in the box” with this relational database—build and manage facilities, OLAP, and data mining. Improved significantly from previous version Scalability has been its limitation historically Architectural improvements to its database engine, Data warehousing features A big boost from fast SMP hardware have enabled SQL Server to compete with IBM and Oracle across most of the scalability curve. The SQL Server in BI ranges from the low-end, the middle and touches the high end in terms of capacity and scalability. Bouayad & Bouzoubaa 42 Comparing BI databases Oracle9i Object/relational database that has long packaged excellent data warehousing features. Wide range of index types, rich join capabilities, and multiple approaches to partitioning. Became a well-integrated business intelligence platform. Release 1: Oracle added OLAP capabilities within its database as well as enhancing build and manage capabilities to support multidimensional warehouses and marts. Release 2: OLAP capabilities were improved and data mining capabilities were added. Bouayad & Bouzoubaa 43 Comparing BI databases Oracle9i Oracle9i now has the advantages of comprehensiveness and integration for all aspects of a BI platform. However, the database also has disadvantages as a BI platform. OLAP and data mining capabilities are newly implemented in the database and neither is well proven or widely used. Even if the capabilities are offered as database features, they’re separately packaged and priced, adding considerably to the initial platform cost. Bouayad & Bouzoubaa 44 Comparing BI databases IBM DB2 (UDB) IBM’s strategic business intelligence database Version for Windows, the leading Unix platforms, IBM S/390 mainframe and AS/400 midrange platforms. Provides good usability in its administrative tools. DB2 OLAP Server provides the business intelligence database for OLAP. DB2 OLAP Server is Hyperion’s Essbase, OEMed, integrated, and re-branded by IBM. Bouayad & Bouzoubaa 45 Comparing BI databases IBM DB2 (UDB) DB2 (UDB): Not tightly integrated within the IBM business intelligence platform. Requires separate build and manage tools and Data mining supported till last version. July 2001, IBM acquired the database technology of Informix Software (Informix RDBMS & Redbrick data warehouse). both viable BI databases. To date functionalities of both remained separate from DB2 and excluded from IBM’s BI platform strategy) Future ?? Customers are confused. They need direction from IBM. Bouayad & Bouzoubaa 46 Comparing BI databases Hyperion Hyperion does not include a BI database. Hyperion should be embedded into a complete BI solution product like IBM DB2 Bouayad & Bouzoubaa 47 Product Comparison Platform Strategy Comparison Comparing BI databases Comparing OLAP Bouayad & Bouzoubaa 48 Comparing OLAP Microsoft SQL Server Analysis Services OLAP functionality includes: The building and management of multidimensional OLAP data models Data Transformation Service: loading and updating of the data models in easily configurable MOLAP, ROLAP, and HOLAP stores a large set of predefined data access and analytic functionality Quantitative analysis functions that include statistical processing capabilities In addition, user-defined functions are supported and Analysis Services provides the documentation and tools for developing them. That’s good power and flexibility. Bouayad & Bouzoubaa 49 Comparing OLAP Oracle Many innocations: a multidimensional storage model through 9i’s Abstract Data Type (ADT) object technology features OLAP query and analytic processing functions within the database provides access to those functions through a set of programming interfaces. OLAP resources integrated within its metadata and management frameworks. Oracle9i OLAP’s storage management and interfaces appear to be brand new. OLAP resources can be managed with the same tools as relational and object resources. Bouayad & Bouzoubaa 50 Comparing OLAP Oracle Advantage: OLAP, relational, and object resources are made scalable, reliable, secure, and manageable by the same set of mechanisms. Disadvantage: lack of maturity. Oracle’s BI platform can implement MOLAP, ROLAP, and HOLAP storage models. Rich analytic processing capabilities Handles the general OLAP aggregation, allocation, and multidimensional navigation functionality. +++ Also packages financial calculations and functions, statistical functions and statistical forecasting, and regression. Microsoft and Hyperion: also package good numeric 51 Bouayad & Bouzoubaa analytic functionality. Forecasting is unique to Oracle Comparing OLAP IBM and Hyperion IBM business intelligence platform uses the OLAP capabilities of the re-branded Hyperion Essbase. Essbase is widely used, well proven, and has broad support from applications and tools partners. Essbase support many platforms: Essbase has become less attractive as a dedicated OLAP system as Microsoft and Oracle has integrated OLAP capabilities into their relational databases, creating comprehensive BI platforms. It requires its own data store, separately managed from the relational data warehousing data store, and its own build and manage toolset. Bouayad & Bouzoubaa 52 Comparing OLAP IBM and Hyperion Hybrid Analysis is the best new feature of DB2 OLAP Server V8.1 Hybrid Analysis allows administrators to define a multidimensional cube that stores its high-level (aggregated or summary) members within a multidimensional store and its low level (detail) members within a relational store. The OLAP Server accesses and prepares the relational data and presents this data to the application as if it were native multidimensional data. It adds HOLAP (Hybrid OLAP) support to the OLAP storage model of IBM’s BI platform. Bouayad & Bouzoubaa 53 Do You know? The difference between MOLAP cubes ROLAP cubes HOLAP cubes Aggregations Bouayad & Bouzoubaa 54 Product Comparison Platform Strategy Comparison Comparing BI databases Comparing OLAP Comparing Data Mining Bouayad & Bouzoubaa 55 Comparing Data Mining Microsoft Microsoft includes data mining capabilities to the OLAP functionality packaged in SQL Server Analysis Services. The best features integration within Microsoft’s BI platform, wizard-driven model building, and the capability to mine relational, OLAP, or external OLE DB data. Analysis Services implements only two data mining algorithms: decision trees and clustering. These algorithms does not cover broad range of problems, additional algorithms would add flexibility. Bouayad & Bouzoubaa 56 Comparing Data Mining Oracle Delivered through Oracle 9i Data Mining, a separately packaged and priced feature of Oracle9i. The best features are the integration within the Oracle9i database, the use of the database for input and metadata, and the broad range of functions and algorithms. Data visualization functionality is missing. There’s no support for a data mining process. Bouayad & Bouzoubaa 57 Comparing Data Mining IBM IBM has been active in data mining much longer than Microsoft or Oracle. IBM Intelligent Miner product has three components: DB2 Intelligent Miner Visualization DB2 Intelligent Miner Modeling DB2 Intelligent Miner Scoring Each supports a key phase of the traditional data mining process. Bouayad & Bouzoubaa 58 Comparing Data Mining IBM All three are separately priced and packaged. The strengths of DB2 Intelligent Miner are the breadth and depth of its data mining algorithms and its modular and comprehensive coverage of the data mining process. Its limitations are complexity—the tradeoff for its power and flexibility, and support only for relational input. Not many business intelligence tools and applications suppliers have either. Bouayad & Bouzoubaa 59 Comparing OLAP IBM uses a single statistical algorithm to discover cells within an OLAP dimension that have unexpected or outlying values and presents them visually to analysts. Analysts can then use traditional OLAP approaches to determine and to understand the causes for value differences. This is a very useful data mining application. Bouayad & Bouzoubaa 60 Comparing OLAP IBM OLAP Server Miner, unlike Intelligent Miner, does not require skill and experience in data mining. OLAP experience is all that you need to use it. This is the right approach to data mining applications. They offer broader and deeper data mining functionality than either Microsoft or Oracle, but they’d be stronger if they were integrated into a single coherent offering. It’s a disadvantage that Intelligent Miner doesn’t mine OLAP data. It’s also a disadvantage that DB2 OLAP Miner has only a single data mining algorithm Bouayad & Bouzoubaa 61 Product Comparison Platform Strategy Comparison Comparing BI databases Comparing OLAP Comparing Data Mining Comparing Interfaces Bouayad & Bouzoubaa 62 Interfaces Microsoft Oracle SQL & PL/SQL ODBC & JDBC IBM Relational Interfaces SQL Transact/SQL ODBC & JDBC OLE DB ADO ADO.NET OLAP Interfaces MDX OLAP DML Essbase API DSO Java OLAP API Pivot Table Service SQL and PL/SQL XML for Analysis Data mining Interfaces DSO Oracle9i Data Pivot Table Service Mining API Wizards (Java) Bouayad & Bouzoubaa SQL & DB2 SQL ODBC & JDBC Hyperion NA Essbase API Intelligent Miner NA C++ SQL Visual tools DB2 OLAP Miner Essbase API 63 Product Comparison Platform Strategy Comparison Comparing BI databases Comparing OLAP Comparing Interfaces Comparing Data Mining Comparing Build and Manage Capabilities Bouayad & Bouzoubaa 64 Build and Manage Capabilities : Toolsets Microsoft Analysis Manager provides comprehensive relational and OLAP build and manage capabilities.

Comparing Build and Manage Capabilities Bouayad & Bouzoubaa 71 Conclusion Microsoft provides a comprehensive business intelligence platform. Build and manage capabilities, OLAP capabilities, and application interfaces are its key strengths. Data mining is very new, although data mining integration and data mining tools are quite good. Bouayad & Bouzoubaa 72 Conclusion Oracle provides a comprehensive business intelligence platform. This platform has a complete set of components, OLAP and data mining capabilities are unproven, but promising. Data mining tools are low level, and build and manage capabilities are not consistently implemented for relational and OLAP data Bouayad & Bouzoubaa 73 Conclusion IBM provides a comprehensive business intelligence platform. Relational data warehousing and data mining are key strengths. OLAP capabilities are very good The platform is not well integrated because they’re OEMed from Hyperion. Build and Manage capabilities require too many toolsets and there’s a disconnect between managing relational data and managing OLAP data. Bouayad & Bouzoubaa 74 Conclusion Hyperion occupies a niche within business intelligence platforms its OLAP technology is a critical component of IBM’s business intelligence platform.
