Slide1:  XML and Storage Michael Hawkins General Manager Business Development Japan, Asia, China, Australia Who is Software AG? XML Adoption Where‘s the pain? The pain relief! XML Server Examples XQuery 37 Years Heritage of Technology Leadership:  37 Years Heritage of Technology Leadership 2000 2002 … Software AG has more than 600 Customers in Financial Services:  Software AG has more than 600 Customers in Financial Services …and more than 3,000 Customers across all Industries worldwide:  …and more than 3,000 Customers across all Industries worldwide XML ADOPTION:  XML ADOPTION Hype Cycle XML adoption curve XML – Here To Stay "XML will continue to be a hot story, though it is unlikely to hit the front pages as much as it has in the past. In some ways, that may be a good thing, as XML makes the transition from topic for debate to forgone conclusion.“ Christopher Lindquist / Ed Dumbill - Jan 2002 Issue of CIO Magazine GARTNER - XML hype cycle 2003:  GARTNER - XML hype cycle 2003 Source: Gartner Group - 05/2003 XML Adoption Curve:  XML Adoption Curve Impact Adoption time line (mainstream usage) Today 2-3 years Minimal Intermediate High WHERE'S THE PAIN?:  WHERE'S THE PAIN? Business drivers The pain - reality check Business Drivers for XML:  Business Drivers for XML Issues: I Application integration Respond faster - improve efficiency - provide better service II Content integration Unified view - effective location of content III Content management Single source / multi channel publishing - workflow IV Device communication Common content format - offline access - synchronization V Other issues Cost reduction - investment risk reduction - customer loyalty Business Drivers (I):  Business Drivers (I) Application integration issues Respond faster to changing business needs and competitive pressure Reduce efforts to adhere to regulatory requirements Mergers & acquisitions require consolidation of services Logistics managemt. – minimize inventory/optimize resource usage Offer new business services (e.g. Web services) Improve Business Efficiency Improve operational productivity of employees Increase efficiency of business processes (e.g. increase automation, manage exceptions) Provide better service to customers, partners and employees Customer self-service over the Web & call center solutions Reduce process cycle time The need for integration:  The need for integration Overwhelming number of data producers and consumers in organizations XML provides way to exchange data Point-to-point integrations have limitations No records, auditing No versioning No cross-application processes Increased complexity Business Drivers (II) :  Business Drivers (II) Content integration issues Provide unified view and access to enterprise content Central content repository to serve hundreds/thousands of users Access to data in productive external sources and applications Allow effective location of pre-existing content Querying structured content - minor problem today Querying unstructured content - inefficient today Unstructured content proliferates Content not yet encoded w/ descriptive metadata Query content in repository and external sources Metadata aggregation & storage required for efficient enterprise-wide searching on unstructured content Business Drivers (III) :  Business Drivers (III) Content management issues Single source publishing - to leverage existing assets Create and store content for maximum reusability and self-service Store XML + associated layout information + other types of data Avoid inconsistencies and redundancies Assemble on demand Repurpose many times in different formats (Web, print, mobile ...) Personalized access to information relevant to a specific subject Workflow Streamline processes for higher efficiency (short response-times ..) Keep enterprise-wide processing of data in sync (log, versioning ...) Access control / authentication Business Drivers (IV):  Business Drivers (IV) Device communication issues Mobile access Common format to transmit content/applications to ext. devices Common internal representation format => XML!!! Content storage and indexing On central server -and- at point of consumption (mobile device) Online searches / cost-effective offline searches (everywhere) Synchronization Between central (staging) server and back end infrastructure Between mobile devices and central server Business Drivers (V):  Business Drivers (V) Other issues Reduce "update"/"administration"/"development" cost Web browser-based administration and access Use standard Web technologies and best-of-breed tools Keep storage efforts for XML documents as low as possible Drive down technology and investment risks IT solutions to be based on open standards No platform lock-in or vendor lock-in Improve customer loyalty With fast, comprehensive and accurate search capabilities Access to up-to-date planning / status data Delivery as promised The pain - reality check:  The pain - reality check Large investment in existing systems that already provide optimum performance for mission critical functions IT infrastructures are and will remain heterogeneous Not ready for Web services - often not even Web-enabled No central point of access / querying to enterprise data They are not connected 85% of application projects do not use integration software Less than 10% of business processes connected to other systems Lack of real-time access and information flow Content inconsistencies - the "cut & paste dilemma" Re-use of existing content is ineffective & yields to inconsistencies Insufficient versioning / revision management Low budgets Tactical, project-based funding but desire long term strategic value Projects are critical to business viability - must show rapid ROI! THE PAIN RELIEF:  THE PAIN RELIEF Value of XML storage in the enterprise Where do we store it? Native versus Enabled XML storage in the enterprise:  XML storage in the enterprise Persistent storage for applications that rely upon business documents A repository for an Enterprise Service Bus integrating multiple enterprise applications A repository for XML content-oriented applications including XML content management A staging server and a repository for all portal-centric content A registry of web services, taxonomies, or other directories (e.g. UDDI registry, metadata repository, ...) A database to manage Web service states, long-term cache, or intermediary between specialized repositories Source: Gilbane Report - June 2003 Where do we store it?:  Where do we store it? File system Text files Utilise existing infrastructure (backup/restore, security, etc) No query/reporting, etc Existing Database Structures Usually an existing RDBMS Utilise the facilities of a database for management/processing, etc XML-based storage Native XML Database/Server RDBMS vs XDMBS:  RDBMS vs XDMBS By design a RDBMS is good to handle normalised table structures XML documents have a kind of hierarchical nested table structure that does not fit into the RDBMS database unless you use features that help to automate this mapping process. XML Document Structure:  XML Document Structure <?xml version="1.0" encoding="UTF-8"?> <musictitle mainclass=“Contemporary" subclass="Rock"> <title titlekey="7">Blues</title> <artist artistkey="E00001">Eric Clapton</artist> <label>Uni/Polydor</label> <product productcode="B00000JNMN" type="CD"> <no.of.disc discnum="2"/> <price> <listprice>24.97</listprice> <ourprice>22.47</ourprice> <saving>2.50</saving> <discount>10</discount> </price> <releasedate day="27" month="7" year="1999"/> <availability avail="1"/> </product> <coverimg src="B00000JNMN.gif"/> </musictitle> Markup content The Logical Structure of XML Documents :  The Logical Structure of XML Documents Relational Database Views:  Relational Database Views XML in a Tamino native XML Server:  XML in a Tamino native XML Server No mapping required: quick development results in short time-to market Native storage: keeping the original structure eg. for legal & auditing purposes High performance: no delay of converting layers in between Scalable: support for 1 to 100000… and more users Native vs Enabled:  Native vs Enabled You’ve got to admit that my storage is clear and organised! Why is XML difficult to handle by RDBMS?:  Why is XML difficult to handle by RDBMS? An RDBMS is primarily designed to handle table oriented data structure and format of data is known prior to storage names and types of data components are fixed and unchanging column descriptions are used for indexing and retrieval without column descriptions we do not know the meaning of the content How to store XML in MS SQL Server? :  How to store XML in MS SQL Server? <CUSTOMER> <CUSTOMERID>1044</CUSTOMERID> <FIRSTNAME>Paul</FIRSTNAME> <LASTNAME>Astoria</LASTNAME> <HOMEADDRESS> <STREET>123 Cherry Lane</STREET> <CITY>Best</CITY> <STATE>CA</STATE> <ZIP>94132</ZIP> </HOMEADDRESS> </CUSTOMER> create table customer ( customerid number(10), firstname varchar(20), lastname varchar(20), street varchar(40), city varchar(20), state varchar(10), zip varchar(10) ); Flatten the xml file: <root><CUSTOMER CUSTOMERID=“1044” FIRSTNAME=“Paul” LASTNAME=“Astoria” STREET=“123 Cherry Lane” CITY=“Best” STATE=“CA” ZIP=“94132” /> </root> Create the stored procedure Pass xml to stored procedure then parse & insert into the table Value of XML for XML repositories:  Value of XML for XML repositories XML document is the basis XML documents can be stored as is - without further conversion Associated open XML standards provide for effective access to document parts or the document as a whole (e.g. XQuery, XPath) Content validation prior to storage (XML Schema) XML-DBs promote automation of document exchange by providing persistent message storage for logging, auditing and tracking of business documents XML provides context to stored information so it can be queried and presented most effectively for intelligent re-formatting –> flexible re-use in multi-channel publishing services XML makes stored content flexible to change Changes in the document structure mainly require a change in the associated schema - little or no data remodeling Caching / staging server:  Caching / staging server XML Database is frequently used as caching server, for example, for online catalogs Ensures performance requirements of business solutions (good response times) Reduces direct load on back-end applications Storing information in XML format makes it easier to create or generate different "skins" (user interfaces / layout) or personalized views on the data Manage multiple languages A Caching Server Enterprise Transaction System Web XML-DB in a service oriented architecture:  XML-DB in a service oriented architecture System of Record Completed Documents: relational - Permanent, long-term storage - System of record - Rigid schema - Normalized and highly typed Operational Data Store Documents in Progress: XML - State data and payload data - Managed for the duration of the process - Shared, updated, audited – iterative extensions - Dynamic (variable) schema XML as an intermediate data representation or middleware layer and storage format to effectively facilitate inter-system communication TAMINO:  TAMINO What is Tamino?
