2121Enterprise Information Integration (EII)Data VirtualizationAs a project-oriented DI middleware, data virtualization is often referred to as virtual data federation,high-performance query or EII. As enterprise architecture, it is frequently described as a virtualizeddata layer, an information grid, an information fabric or as data services in SOA environments.EII is a middle tier query server: contains a metadata layer withconsolidated businessdefinitions. Communicates through webservices, database connections,or XML; Listener waits for a request –sends whatever queries areneeded across whatever datasources are required to returndata to the requestor; Metadata robustness is thedifferentiator. Federated data stores produceaccessibility to enterprise datawithout forcing central control.
2222Technology Overview:EII (Enterprise Information Integration)EII toolsCreate virtual views of distributed enterprise data through queries executed in real timewithout physically moving or copying data* Also known as data federation; virtual data warehousing; data virtualizationBenefitsLatency: Through federated queries, information can be accessed within millisecondsStorage: Data is not moved or copied from source systems, so additional storage is notrequiredDrawbacksVolume: Should only be used for small targeted data setsQuality: Minimal transformation capabilities — efforts to include will negatively impactlatencyWhile never making a material impact as a pure-play market, datafederation is an important part of the data integration platform, but needto watch out for high level integration and maintenance effort
2323Enterprise Application Integration (EAI)•EAI is focused on moving data between Enterprise Applications with business logic applied. It picks up anapplication transaction and initiates a transaction in another system, for example CRM system picks up a neworder and enters it into your Financial Application. Driven by business events Connectivity between applications Information consistency a key requirement Bus/hub with application adaptors Wire-level messaging protocols
2424Technology Overview:EAI (Enterprise Application Integration)EAI ToolsThese products, which started out as rudimentary software that supported basic messaging,routing, and data transformation needs, have grown into more sophisticated tools that nowalso provide full support for SOA as well as electronic data interchange (EDI).BenefitsLatency: Through message based orchestration, information can be transferred withinseconds to service real-time data integrationEvent based: Data transfer can be triggered by eventDrawbacksProprietary: Traditional EAI vendors used proprietary protocolsQuality: Data validation can be performed, however doing it with match &merge multiple source systems is not the strength of this toolsetEAI toolset can be brought in as a middleware framework to support SOA,however with insufficient in-house experience, a POC is recommended.
2525Extract Transform Load (ETL)As a data integration hub, ETL products connect to a broader array of databases, systems, andapplications as well as other integration hubs. ETL batch architecture is generally split into 4 majorcomponents: Extract, Clean, Transform and Load. Provide expanded functionality, especially inthe areas of data quality, transformation, andadministration Coordinate and exchange meta data amongheterogeneous systems to deliver a highlyintegrated environment that is easy to use andadapts well to change Capture and process data in batch or near-real time using a standardized informationdelivery architecture Provide greater performance, throughput, andscalability to process larger volumes of data athigher speeds Load data more quickly and reliably, by addingchange data capture techniques, continuousprocessing, and improved runtime operations.
2626Technology Overview:ETL (Extract, Transform and Load)•ETL toolsBatch or incremental extraction of high volumes of data from one or more sourcesAble to run complex transformations on the data which can include cleansing, reformatting,standardization, aggregation, or the application of any number of business rulesLoads the resulting data set into specified target systemsBenefitsVolume: Manages extremely high volumes of data movementQuality: Allows for complex data transformations, enabling much higher quality, hence moreusable informationRe-Use: Routines to extract/transform/load can be re-used by many applicationsDrawbacksLatency: Optimized when scheduled as batch data movement as opposed to real-time oron-demand. By reducing the volume throughput (with CDC) ETL can be used to meetoperational near real-time requirements.Performance: Extracts can cause performance impacts to source production systems, solow-impact batch extraction “windows” need to be identified, or use CDC.ETL has spread beyond data warehousing and can supports near real-timedata integration for both operational and BI applications
27Change Data Capture (CDC)•CDC Integration Suite provides secure, high-volume, real-time, and bi-directional data integration andtransformation between applications. This product supports a wide range of databases, including thosethat run on legacy, back-office, and other operational systems on different platforms.27Journal LogRedo/ArchiveLogsPublisherEngineAnd MetadataSubscriberEngineAnd MetadataTCP/IPGUIUnified AdminPointWith MonitoringDatabaseAuditDatabaseMessageQueueWebServicesBusinessProcessPublisher Subscriber• Provide a pseudo to actual real-timeupdate capabilities• Heterogeneous system and platformsupport• Real-time selective data capture anddelivery• Limited data transformation• High performance even with very highvolumes;• Guaranteed integrity of datatransactions- 2 phase commit
2828Technology Overview:CDC Change Data CaptureCDC toolsThe optimal approach is to capture “deltas” or changes in the source data created orupdated in operational systems as they are written to the DBMS log files and make themimmediately available in real-time to downstream applicationsBenefitsVolume: Captures only changes or “deltas” since last pull from source databases,reducing amount of data that needs to be movedPerformance: With the option to access database log files versus production database —no performance impact to source operational systemsLatency: Can enable continuous updates throughout the dayDrawbacksLatency: No latency issue. Due to source log reading, source system down timecould cause extra administrative task to synchronize and monitor dataPerformance: Data transformation ability is more limited unlike ETL toolsCDC could be an option to combine with ETL for the enablement of near real-time and more throughput, with less impact to source systems.
3030Technology Overview:ESB (Enterprise Service Bus)•ESB toolsThese technologies typically incorporate adapter technology to connect to a variety ofapplication and database types, ability to route transactions according to business rules andtransport transactions from source to target with low latency.BenefitsOpen: More open than EAI tools. Universal support for distributed processingExternal Entities: ESB is easier to configure and implement; hence often chosen tosupport B2B applicationsDrawbacksVendor: ESB only vendors are smaller than EAI vendorsExperience: Lack of Chevron internal working and support knowledgeESB is best used for establishing business processes (BPM) andorchestration infrastructure that will leverage a business services layer tosupport SOA across the entire enterprise. ESB federation can also beimplemented to mitigate drawbacks.

4444Data Integration StrategyDecision Rationale - continuedInteroperability• Partner orchestration of BizTalk and Share point portal.• Standard ETL and BI toolsets with web service to prove interoperability across the platforms.Supportability• Continue to use PI as data transfer hub between Plant Information Network (PIN) andProcess Control Network (PCN) - Leverage what exists increases supportability. Apply PCISstandards to utilize OPC for PI integration.• GDST and Refinery have experiences with implementing and supporting ETL. ITC providesservices for ETL support, database support and BI support.Total Cost of Ownership• Using EAI and ETL standard toolset to facilitate refinery centrally managed process and dataflow would bring cost benefit in leveraging enterprise support and license costs.• Infrastructure and resources for ETL toolset may be shared with Lynx within refineries whichcan greatly reduce license and support cost.
4545Data Integration ArchitectureDecision Rational - continuedSustainability• EAI and workflow provides the foundation for SOA framework and adaption of newertechnology (composite software and Web 2.0 ) is feasible• Once we gain more experiences with EAI and workflow toolset, it can be expanded tohandle more integrations to accelerate SOA.• We will maintain ETL as a foundation to add on real-time and on-demandcomponents.• SOA still maturing. Work with ITC to ensure we remain consistent with the companydirection of SOAData Management• Info Mgmt disciplines provide Data Governance, Master Data Management,Metadata Management and Data Quality improvement.• Using data integration hub to provide standardized data layer provides a goodfoundation for information management.

Most data was required in real time to capture tradedeals.– ETL platform for application integration with robusttransformation.– Orchestration tool (Bitzttalk) facilitates work flow and dataintegration with external parties and systems.57
6060Best Practices for Data Integration1. Don’t loose sight of DI Architecture vision, however include tactical dataintegration solution for specific business requirements. (phasedapproach)2. Categorize data in business value and usage. (prioritize)3. Prioritize the sequence of implementing data integration. (sequence)4. Document data migration and infrastructure deployment roadmap.5. Establish new standards for naming, data types and metadata.(governance)6. Publish metadata definitions and glossaries of business terms.7. Establish a coexistence strategy with legacy systems. Always have amigration plan.8. Establish physical reference architecture and tools.9. Implement environments for the foundation components ahead of time.10.Begin data migration into the integrated environment.
6161Planning for Data Migration•Data Migration (Conversion) from legacy system to the newly integratedenvironment needs to be considered carefully by weighing highest valuevs. highest usage.– Foundation Data Migration - Implementing the main lookupdata, or master data, for enterprise– Core transactional data migration - Detailed transactions for thebasic enterprise events– Application data migration – Supports specific companyfunctions•This strategy leverages the building of foundational master data thatwill be most often queried by end users, then adding core transactionaldata that adds value and incrementally allows more business value asdata becomes richer in content.

6363Integrating Data Content and Meaning•Another aspect of data integration is standardizing the usage of data contentand meaning. This type of data content integration yields business efficienciesand quality of data.– Integration of content standardizes data values, e.g. lookup codes, acrossdifferent data bases. (For example, if PI Tag or P&ID needs to be uniquelyidentified at the global level across all refineries, a newly defined uniqueID can be created and tied with existing ID.) Depending on local operationor global data analysis, two sets of ID can be translated and delivered tosatisfy user request.– Besides the physical data movement and storage of integrated databases, the common integration of data meaning needs to bestandardized. Metadata provides definitions of subject areas, tables, andcolumns in a data repository.– When all users refer to the data repository, the meaning of each dataelement is standardized to a common definition.– Additional metadata can be provided that displays calculations forderived data elements, glossaries of business terms, and lineage of thesource of data.
6464Data Integration Architecture considerationsCommonality, consistency and interoperability of DI components: Minimal number of products or product suites supporting all datadeliveries Single metadata repository and/or the ability to share metadataacross all components Common design environment to support all deliverables Interoperability with other integration tools and applications Efficient support for all data deliveries regardless of runtimearchitecture (centralized vs. distributed )
6565Decision Making methodologyTop-down•Integrate Use Case with Pattern Matching•Using integration-pattern matching, look for matches by comparing theirspecific use cases with “typically deployed” Data Integration patterns.Examples:• To improve Global Manufacturing-wide reliability reporting, theappropriate integration pattern would be an enterprise datawarehouse that physically consolidates and summarizes OE datafrom across all refineries.• To provide operational DCS information to business levelapplications and for operational BI, an replicated operation datastore that stores up-to-the-second transactional data would be thebest fit.• To support upstream or downstream product movement analysisand establish a performance, a data mart or an OLAP cube sourcedfrom the ODS or Data Warehouse would be the best pattern.
6666Decision Making methodologyBottom-upAssessing integration factorsThis is often valuable where the DI decision is complex and/or where a clearintegration pattern match is not obvious. For example, to determine whethervirtual, physical or a hybrid combination: If data extracted from many source systems could be used by many othersystems, then physical data store is good for data reuse and futureexpansion. If significant data cleansing and complex transformation are required,then physical data consolidation is typically the most practical choice. If harmonized data need to be aggregated, summarized to provide foranalytical dashboard, then physical data store is needed to load into DataWarehouse/Data Mart and/or OLAP cubes. If source systems are mostly available as system of record, data can bepassed between systems without significant data matching, merging orharmonizing, then virtual makes sense. Hybrid combination may be a good choice if a project has both real-timebusiness process integration and large amount of data interfaces.

7272Use Cases of EAI, ETL, EAI + ETL•EAI SoftwareAn example - During the Internet boom, companies flocked to EAI to connect e-commercewith back-end inventory and shipping systems to reflect product availability and deliverytimes.•ETL toolset in an ‘always awake’ mode – near real timeTo deliver near-real-time capabilities. The ETL tools typically use application-level interfaces to detect new transactions or events as soon as they aregenerated by the source application. They then deliver these events to anyapplication that needs them either immediately (near real time), at predefinedintervals (scheduled), or when the target application asks for them (publish andsubscribe).•EAI plus ETLEAI tools captures data and application events in real time and passes them tothe ETL tools, which transform the data and loads it into the BI environment.
737373What vendors say about ESB?– Some stress the role of the ESB in eBusiness, its inter-organizational. Rather than intra-organizational role– Almost all believe, that the ESB is more than the bus it runs on. Essentially, they aredescribing a service-oriented architecture from another viewpoint– Some see orchestration as part of the ESB architecture, others do not– Some package MOM and EAI in their ESB products– Some identify event monitoring as the major differentiator from MOM– Some consider services management as part of the ESB solution– Some see an ESB as strictly related to Web services and describe it as a Web ServicesNetwork.All Vendors are “flexible” in defining ESB. Their definition always manages to show that theircurrent solutions are using it
7474ESB, When to Consider– When deploying SOA across the enterprise– When establishing business processes (BPM) and orchestrationinfrastructure that will leverage a business services layer– When moving from a complex point-to-point or ‘spaghetti’ architectureto a more manageable and flexible IT infrastructure– When integrating to multiple and heterogeneous data sources andapplications– When there is heavy business logic and security through the service busto multiple end points– When further separation from composite applications is required (awayfrom underlying implementations)– When flexible coupling is required
7575Information (Data) Services in SOA•For data to be a first-class citizen in the SOA world, a clear separation must exist between dataconsumers and data providers. This separation mirrors the principle that service consumers andproviders must be distinct and separate in an SOA. Furthermore, this separation must be delineated byan interface, or contract, that both providers and consumers share
7676Gartner on SOA and Data ServicesGartner suggested that success in loosely-coupled service-oriented business applications(SOBAs) becomes more difficult since each design point has to verify it own semantics,context and data structures.Key FindingsUnder a loosely-coupled architecture, data stewardship and governance best practices can besupported by data services within an SOA instead of embedding such practices within applicationlogic. Where people and processes were formerly embedded in application design, they now fallunder the domains of business process platforms and EIM - Enterprise Information Management.PredictionsBased on lessons learned through data warehouse, data mart and operational data storeimplementation practices, 60% of failed information-as-a-service initiatives through 2009 will list alack of an effective data governance strategy as one root cause of failure.RecommendationsOrganizations should begin their selection of data profiling, quality, mining and master datamanagement tools with the end goal of deploying all the logic and processing within these tools asservices that can interoperate and execute actions on behalf of and against data used by SOBAs, and as acallable service by business context services.

Web 2.0 (1)78One’s view of Web 2.0 is highly dependent on one’s background and interest, and can best bedescribed by these three anchor points:Technology and architecture – consists of the infrastructure of the Web and the concept ofWeb platforms. Examples of specific technologies include Ajax, Representational StateTransfer (REST) and Really Simple Syndication (RSS.) Technologists tend to gravitate towardthis view.Community and Social – looks at the dynamics around social networks, communities andother personal content publish/share models, WIKIs, and other collaborative-contentmodels. Most people tend to gravitate toward this view, hence, there is a lot of Web 2.0focus on “the architecture of participation.”Business and process – Web services-enabled business models and mashup/remixapplications. (A mashup is a Web site of Web application that combines content from morethan one source.) Examples include long-tail economics and advertising and subscriptionmodels such as a service (SaaS.) Of course, business people tend to zero in on this angle.
