3 Agenda Access to relational Databases from XPages JDBC Driver to access NSFs

4 New XPages Data Sources for RDBMS XPages leverages JDBC when connecting to relational databases Accesses any database with a JDBC driver available You could access DB2, Oracle, MS SQL, MySQL, Derby... you name it! You need to obtain the JDBC driver from the database vendor or third party provider RDBMS data is accessed directly no synchronization is performed with NSF XPages efficiently manages the connections through a connections pool Uses NSF specific connections The data is accessed using a set of dedicated data sources

5 New XPages Data Sources for RDBMS extlibx library adds 2 new data sources: JDBC Query for Read Only access JDBC RowSet for CRUD (create/read/update/delete) access. Current implementation is based on com.sun.rowset.cachedrowsetimpl, Could be configured to use your own via the rowsetjavaclass property Each of the provided new data sources could be easily utilized either by: the core View Container Control (xp:viewpanel element) the XPage itself (xp:view element ) The new data sources are now available in the Domino Designer Property Panel

6 Server Side JavaScript APIs @JdbcExecuteQuery Used to simplify various RDBMS operations Allows programmatic access to RDBMS data

7 XPages Extension Library Demo App DEMO of the Domino Designer view control configuration, with the new JDBC data sources: JDBC Query usage JDBC RowSet usage

8 Agenda Access to relational Databases from XPages JDBC Driver to access NSFs

9 Domino JDBC Access Currently a preview technology delivered on openntf Expose Domino data to external applications Allow data analytics on top of Domino data Fully support the Notes/Domino security model Use the Internet user/password Connect from any application that supports JDBC connectivity Augment the Domino query capability with a new SQL engine working on top of the Domino data (views) Use SQL for dynamic queries, including custom selection, aggregation operators... Supports very complex queries on top of Domino data Dynamically re-sort view entries without creating an index Join data between multiple views, even coming from different databases/servers Aggregate data from different views/databases/servers Bring all the power of SQL to Domino data :-) Make it easy to consume from an XPages application Tightly integrated with the XPages Extension Library RDBMS extension Execute queries with the rights of the XPages user (a.k.a Web User )

10 DomSQL in a Nutshell Gives read-only access to the data, by projecting the content of views as relational tables Exposes the Domino data through a JDBC interface Includes data and metadata access DomSQL is based on top of an award winning SQL engine: SQLite Very robust SQL engine used by many projects ( Well known SQL grammar understood by many JDBC clients Multiple execution modes Executes within the HTTP process for XPages consumption Maximum performance, no network connection involved Executes within the DOTS process when accessed remotely Remote server implemented using RMI The engine is fully extensible, if needed The source code is provided under the Apache license, and it is only using the C toolkit public API.

11 Use it From XPages with the Extension Library Relational data definition Relational Datasource (Extension Library) JDBC Connection (Extension Library) Any XPages Control that can bind to data (views...)

12 Or From Any Third Party Application That Supports JDBC Connectivity Birt Report Editor DBVizualizer
