18 IBM Analytics Banking Student Loan Processing Optimizing ETL to enabling faster loan review and approval Mountains of data to process Poor data quality, complicated by millions of records to process took 12 hours to load Faster Time to Insight accessing more than 7 million records went from 12 hours to less than 13 minutes Improved TCO Complex joins in-memory were performed on the mainframe, with 93% on ziip engine Software IBM Virtualization Manager for z/os The challenge: Student loan processing was taking too long due to poor data quality and huge volumes of student data stored in IMS DB on the customer s z12 mainframe. With IBM Virtualization Manager for z/os accessing more than 7 million IMS records, the cycle went from 12 hours (via ETL) to less than 13 minutes. Complex joins in-memory were performed on the mainframe, with 93% of related processing running on the System z Integrated Information Processor (ziip). The lending institution was able to use real-time insight to processing student loans faster and more accurately improving business efficiency and avoiding regulatory fines.

19 Unlocking Z for Real-time Business Insight Simple Get transactional access, no data movement Open to all Apps Modern APIs enable access Secure Avoid risk by reducing moving data off Z Systems IBM Virtualization Manager for z/os Fast Exploits Z architecture, including parallelism and in-memory processing Cost Effective Keeps Z costs down with up to 99% ziip offload Non z/os data

20 IBM Analytics Insurance North American Insurance Firm Modernization to accelerate adding new online customers From days to milliseconds Online account origination went from 3 days to 200 milliseconds, Improved operational efficiency Overcame time delays associated with inefficient batch processes API-enabled IBM Z apps/data Enhanced developer productivity with APIs to actuarial data in IMS DB Software IBM Virtualization Manager for z/os IBM z/os Connect Enterprise Edition The challenge: New online customers at major insurance company had to wait days for confirmation of coverage when adding a new insurance product (motorcycle, boat, RV, etc.). Batch processes associated with their policy management system running on their z13 mainframe contributed to the new product request taking approximately 3 business days to complete. Actuarial data in IMS DB was API-enabled using IBM Virtualization Manager, which allowed developers to incorporated risk calculation and cost estimates into new online service. Online policy origination went from 3 days to 200 milliseconds, and registered 400+ new policies in the first 2 weeks of going live.

21 IBM Analytics Financial Services Global Financial Services - Real-time, self service analytics for faster insight into customer investment needs 17 million VSAM records Huge data volumes 15 VSAM files concatenated together brought back 17 million records Faster time to insight Enabling portfolio managers to provide timely investment advice Real-time information For business analysts who no longer waited for data to be loaded Software IBM Virtualization Manager for z/os The challenge: Prior to doing analytics, business analysts had to enlist database programmers to create reports from VSAM data residing on the IBM z13 mainframe. Getting mainframe data into the data warehouse involved a complicated, multi-step extraction process that created delays for business analysts. IBM Virtualization Manager enabled real-time access to IMS DB and VSAM data from the online dashboard of the business intelligence application. Analysts can respond faster to business requests for customer insights enabling portfolio managers to use the intelligence to make more relevant, timely investment suggestions to their clients.

24 Runtime flow Sources Transaction Transaction (Mainframe) Integration Analytical Lake Storage Discovery & 2.1 Exploration ETL 2 Landing Zone 3 4 Enterprise Warehouse (and Marts) Archive 5 Engineering 6 7 Stewardship Discovery Actionable Insight Interactive Workloads Long-Running Workloads 1. Transaction data is extracted on a periodic basis or from operational systems. 1. Mainframe data can be directly access for Discovery & Exploration 2. Mainframe data is extracted based on needs and use case (not all data needed or should be moved) 2. is ingested into the analytics environment using an ETL engine (Stage or BigIntegrate) which generates the technical and operational metadata and stores it in the metadata repository for access during Engineering, Stewardship and Discovery. 3. is placed initially, when needed, in a Landing Zone (Hortonworks) where it can be staged, transformed and integrated. 4. is then loaded into an Enterprise Warehouse (DB2, dashdb, PDA, IDAA) and possibly to downstream marts (IDAA) for reporting, dashboarding and other interactive workloads. 5. As data ages, it is extracted from the Enterprise Warehouse (again using the ETL engine) and loaded into the Archive repository (Hadoop) where it can be accessed for long-running workloads such as exploratory analytics 1. DB2 for z/os transaction historical data can leverage IDAA capabilities to archive data 6. in either location (and its associated metadata) can be accessed for Engineering, modeling etc., using InfoSphere Architect. I can be accessed for Stewardship (curation, adding business metadata etc) and Discovery using the Information Governance Catalog UI. 7. Business Users and Scientists can access data either directly or through virtualization/federation tools such as BigSQL, IDVM. The users then visualize and analyze the data using their favorite tools (Cognos, SPSS, R Studio, QMF, etc.)

25 Mainframe data sources Traditional sources: The original corporate data sources are still very valuable resources. They are made up of application data (CRM, HR, and other customer data systems), transactional data (sales, events, claims, etc.), systems of record (historical data, reference data, etc.) and third-party data (provided by 3 rd part organizations e.g. census data). DB2 IMS VSAM Other 3 rd party DB Log (SMF,RMF, Midleware) DB2: High performance RDBMS In memory capabilities to even fast performance Exploration of NoSQL capabilities with native support of XML, JSON (up to 540 million transactions per hour arriving through a RESTful web API into DB2) Together, with IDAA, delivers real hybrid transactional analytical processing IMS: High performance NoSQL database (hierarchical). Fast Path High Volume Transaction Processing reaching a sustained average transaction rate of over 117,000 transactions per second on a single IMS instance. VSAM: Virtual Storage Access Method, another NoSQL database on mainframe, extreme performance. DB2 and IMS are based on VSAM. VISA process up to 145k transactions per second Logs: Another very important source data. The logs on mainframe has well defined data structure which can and should be used for analytics

26 Mainframe Analytical data lake storage Component Description: The overall purpose of the Mainframe Analytical Lake Storage component is for it to be a set of secure data repositories allowing for Discovery and Exploration of real time data, performing Actionable Insight, and utilizing Enhanced Applications, without a need to physically move from it source. Although is not mandatory, it can be use to control mainframe costs and have fine tune workload management DB2 IMS IDAA Sharing allows applications running on more than one DB2 or IMS subsystem to read and write to the same set of data concurrently. Possible architectures includes one DB2 member for transactional workload and one DB2 member as for analytical workload. Avoid unnecessary ETL, start the exploration and discovery right on transactional data without impacting applications DB2: HTAP (Hybrid Transactional/Analytical Processing) Leverage the same infrastructure to run any kind of workload. bases on DB2 are logical objects. It gives the possibility to have a transactional and analytical data model controlled by the same RDBMS. One OLTP application can access analytical data One OLAP application can access transactional data IDAA: Can be used to deploy a data warehouse and or specific data marts directly on the mainframe. IMS, VSAM, and other mainframe data can be loaded directly to be used in temporal data marts. Archive historical DB2 data to free up mainframe storage keeping it accessible

27 access Component Description: The overall purpose of the Access component is to express the various capabilities needed to interact with the Lake Repository component. The capabilities serve the access needs of data scientists, business analytics, developers, and others that need access to valuable data. virtualization: Describes any approach to data management that allows a user or application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted or where it is physically located. SparkSQL IDVM BigSQL SparkSQL Securely Integrate OLTP and Business Critical, can access almost all type of mainframe data Same distribution, no need for mainframe skills. Same set of applications language can be used: Scala / Python / Java / R / SQL Can be called from BigSQL IBM Virtualization Manager for z/os: The base for several IBM products such as QMF, Spark for z/os, IDAA Loader, etc Virtualized almost all data on mainframe, including 3 rd parties DBs, like Adabas, IDMS Can virtualized BigSQL objects to easier integration with hadoop environments Can also virtualized other distributed data stores BigSQL: Hadoop query engine derived from decades of IBM R&D investment in RDBMS technology, including database parallelism and query optimization. Can access DB2 for z/os directly thru DRDA connection Can access mainframe data thru IDVM Can access mainframe data thru SparkSQL
