  6. 6. VIRTUAL DATABASEVIRTUAL DATABASE A virtual database (VDB) provides a unified view of data residing in multiple physical repositories. A VDB is composed of various data models and configuration information that describes which data sources are to be integrated and how. In particular, source models are used to represent the structure and characteristics of the physical data sources, and view models represent the structure and characteristics of the integrated data exposed to applications.
  7. 7. ACCESS L AYERACCESS L AYER The access layer is the interface through which applications submit queries (relational, XML, XQuery and procedural) to the VDB via JDBC, ODBC or Web services.
  8. 8. QUERY ENGINEQUERY ENGINE The heart of DV is a high-performance query engine that processes relational, XML, XQuery and procedural queries from federated datasources. Features include support for homogeneous schemas, heterogeneous schemas, transactions, and user defined functions. When applications submit queries to a VDB via the access layer, the query engine produces an optimized query plan to provide efficient access to the required physical data sources as determined by the SQL criteria and the mappings between source and view models in the VDB. This query plan dictates processing order to ensure physical data sources are accessed in the most efficient manner.
  9. 9. CONNECTOR ARCH ITECTURECONNECTOR ARCH ITECTURE Translators and resource adapters are used to provide transparent connectivity between the query engine and the physical data sources. DV includes a rich set of Translators and Resource Adaptors that enable access to a variety of sources, including most relational databases, web services, text files and LDAP. A translator is used to convert queries into source-specific commands, and a resource adapter provides communication with the source. Need data from a different source? A custom translators and resource adaptors can easily be developed.
  10. 10. DESIGN TOOLSDESIGN TOOLS Various design tools are available to assist users in seeting up JBoss Data Virtualization for an integrated solution. MOVE DOWN TO EXPLORE THE CONCEPT OR RIGHT FOR THE NEXT CONCEPT
  11. 11. DATA VIRTUALIZATION DESIGNERDATA VIRTUALIZATION DESIGNER The designer is a visual tool that enables rapid, model-driven definition, integration, management and testing of data services without programming using the DV runtime framework. With the designer you can: create a virtual database (or VDB) containing your models, views, procedures, dynamic XML documents which you deploy to DV server and then access your data. resolve semantic differences create virtual data structures at a physical or logical level use declarative interfaces to integrate, aggregate, and transform the data on its way from source to a target format which is compatible and optimized for consumption by your applications Preview your data

  14. 14. CONNECTOR DEVELO PMENTCONNECTOR DEVELO PMENT The process of integrating data from an enterprise information system into JBoss Data Virtualization requires one to two components: a translator (mandatory) and a resource adapter (optional), also known as a connector. Most of the time, this will be a Java EE Connector Architecture (JCA) Adapter. A translator is used to: translate JBoss Data Virtualization commands into commands understood by the datasource for which the translator is being used, execute those commands, return batches of results from the datasource, translated into the formats that JBoss Data Virtualization is expecting. https://access.redhat.com/documentation/en- US/Red_Hat_JBoss_Data_Vir tualization/6.1/html/Development_Guide_Volume_4_Server_Development/Introduction_to_the_JBoss_Data_Serv ices_Connector_Architecture.html
  15. 15. CONNECTOR DEVELO PMENTCONNECTOR DEVELO PMENT (CONTINUED)(CONTINUED) A resource adapter (or connector): handles all communications with individual enterprise information systems, (which can include databases, data feeds, flat files and so forth), can be a JCA Adapter or any other custom connection provider (the JCA specification ensures the writing, packaging and configuration are undertaken in a consistent manner), removes concerns such as connection information, resource pooling, and authentication for translators.

  17. 17. ADDITIONAL CUSTOMIZATIONSADDITIONAL CUSTOMIZATIONS JBoss Data Virtualization is highly extensible in other ways: You can add user defined functions. You can adapt logging to your requirements, which is especially useful for custom audit or command logging. A delegating translator can be used to add custom code to all methods for a given translator. You can also customize authentication and authorization modules. See the Red Hat JBoss Data Virtualization Security Guide.

  19. 19. RESOURCE ADAPTORSRESOURCE ADAPTORS With the exception of JDBC data sources, JBoss Data Virtualization provides a JCA adapter for each supported data source. These are the resource adapter identifiers, as specified in the server configuration file: File Adapter - file Google Spreadsheet Adapter - google Red Hat JBoss Data Grid (6.1 & 6.2) Adapter - infinispan LDAP Adapter - ldap Salesforce Adapter - salesforce Web Services Adapter - webservice Mongo DB Adapter (technical preview) - mongodb A resource adapter for the JDBC translator is provided with JBoss EAP by default.
  20. 20. ADMINISTRATIVE TOOLSADMINISTRATIVE TOOLS AdminShell- AdminShell provides a script-based programming environment enabling users to access, monitor and control JBoss Data Virtualization. Management Console - The Management Console provided by the Red Hat JBoss Enterprise Application Platform (EAP) is a web-based tool allowing system administrators to monitor and configure services deployed within a running JBoss EAP instance, including JBoss Data Virtualization. Management CLI - The Management CLI (command-line interface) is provided by JBoss EAP to manage services deployed within a JBoss EAP instance. Operations can be performed in batch modes, allowing multiple tasks to be run as a group. JBoss Operations Network - Red Hat JBoss Operations Network provides a single interface to deploy, manage, and monitor an entire deployment of Red Hat JBoss Middleware applications and services, including JBoss Data Virtualization. Dashboard Builder - The Dashboard builder allows connection to VDBs through the DV JDBC driver to visualize the data for testing and Business Analytics.

  21. 21. THE ADMIN SHELLTHE ADMIN SHELL AdminShell provides the following features: Administration - AdminShell can be used to connect to a JBoss Data Virtualization instance in order to perform various administrative tasks. Data Access - AdminShell can be used to connect to a virtual database (VDB) and run SQL commands to query VDB data and view results. Migration - AdminShell can be used to develop scripts that will move VDBs and associated components from one development environment to another. (Users can test and automate migration scripts before executing them in production deployments.) Testing -The built-in JUnit Test Framework allows users to write regression tests to check system health and data integrity. The written tests validate system functionality automatically, removing the need for manual verification by QA Personnel. https://access.redhat.com/documentation/en- US/Red_Hat_JBoss_Data_Virtualization/6.1/html/Administration_and_Configuration_Guide/sect -AdminShell.html
  22. 22. THE MANAGEMENT CONSOLETHE MANAGEMENT CONSOLE The Configuration tab contains general and JBoss Data Virtualization specific configuration properties. Runtime tab shows runtime information about JBoss EAP server and Teiid subsystem. You can view runtime information about Teiid by clicking Virtual Databases in the left hand navigational tree. You can configure roles and groups using the Administration tab. Roles for a user to be included in and excluded from can be configured in the Management Console. You can also configure groups to be included or excluded from a role. Only users in the SuperUser or Administrator roles can perform this configuration. https://access.redhat.com/documentation/en- US/Red_Hat_JBoss_Data_Virtualization/6.1/html/Administration_and_Configuratio n_Guide/sect-Management_Console.html
  23. 23. MANAGE MENT CLIMANAGE MENT CLI The Management CLI features a help dialog with general and context-sensitive options. Easy to launch and connect with the EAP_HOME/bin/jboss-cli.sh - -connect or jboss-cli.bat https://access.redhat.com/documentation/en- US/Red_Hat_JBoss_Data_Virtualization/6.1/html/Administration_and_Configura tion_Guide/sect-Management_CLI.html
  24. 24. JBOSS OPERATIONS NETWORKJBOSS OPERATIONS NETWORK JBoss Operations Network has additional agent plug-ins to manage other JBoss products. Although these are JBoss ON resource plug- ins, they are included in separate packages and require a separate subscription to download them. https://access.redhat.com/documentation/en- US/Red_Hat_JBoss_Data_Virtualization/6.1/html/Administration_an d_Configuration_Guide/sect- JBoss_Operations_Network.html#Installing_JBoss_Agent_Plug- in_Packs
  25. 25. DASHBOARD BUILDERDASHBOARD BUILDER Red Hat JBoss Dashboard Builder can be connected to an external database, be it using JNDI of the container or connecting directly only using the JDBC driver to access the database. Connections to databases can be configured in workspace Showcase on page External Connections. After you have established the connection to the database, you need to create a data provider that will collect the data from the database and allow you to visualize it as an indicator in the dashboard area of a page. Note that Red Hat JBoss Dashboard Builder makes use of its own local internal database to store its local data. This database is read-only for Dashboard Builder, but is accessible from outside.
