The information on the roadmap and future software development efforts are intended to outline general product direction and should not be relied on in making a purchasing decision.

Agenda

• Overview of database connectivity with Accelrys Enterprise Platform

• Connection technologies• Connection types• Component access• Data source configuration• Common pitfalls

ETL Processing

• Objective: Facilitate movement and transformation of data

• 3 Functions– Extract data from remote sources– Transform Data (Standardize,

reformat etc.)– Load data to a target system

• Focus on Extraction and Load using Data Sources

• The Integration collection includes a set of components designed for Database connectivity.

• Pipeline Pilot Server can access databases that are ODBC or JDBC compliant

• Allows connections to a variety of compliant databases (Oracle, SQL Server, MS Access, etc.)

• Data sources are defined and administered through the Administration Portal. – The client machines do not require configuration

• Network databases are accessed through the SQL components through data Sources.

Database Connectivity

Connection Technologies

• Open Database Connectivity (ODBC)– Better peformance for simple data selection

• Java Database Connectivity (JDBC)– Selection of LOB’s– Oracle proxy connections– Wider array of connections available.

– Batch insert and update now supported in ODBC and JDBC (8.5)

Performance: ODBC v JDBC

Performance: Batching

Connection Types

• Connection String– Configured within components

• DSN– Data Source connection manager (Windows)– ODBC.ini file (Linux)

• Pipeline Pilot – Administration Portal– Required for JDBC

• AKA Connection strings

• Configurable directly on the component

• Currently supported for ODBC only

Example:Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\mydatabase.accdb;Uid=Admin;Pwd=;

DSN-less connections

Demo• Component Configuration

Configuring via DSN

• Managed through ODBC Data Source Administrator on Windows

• Managed through a configuration file on Linux called ODBC.ini

• Consolidation of connections

• Import / Export functionality

• Assignment of global credentials

• Set connection access levels

• Required for JDBC

Configuring via the admin portal

Demo• Admin Portal configuration

Common connection problems

• SQLDescribe Param• 32-Bit vs. 64-Bit• 4000 character limitation• MySQL community driver

Summary

• What we learned– Accelrys Enterprise Platform supports ODBC and JDBC connections– Connections can be established 3 ways

• DSN• Connection String• Pipeline Pilot Data Source

– How to manage data source globally through the admin portal– How to configure components to use these data sources

• What Now?– Contact your account manager to inquire about the integration collection– Take a look at our available resources for more information
