Cisco enters Data Virtualization Space

In case you haven't heard, networking  giant CISCO systems on Thursday June 20th, 2013 announced that it is buying Composite Software http://www.zdnet.com/cisco-to-acquire-composite-software-for-180m-7000017085/ for $180 Million This acquisition highlights the growing interest in the Data  Virtualization market by customers that vendors are trying to fill. The phrase Enterprise Information Integration ( EII ) was first introduced by MetaMatrix (which is predecessor for Teiid http://teiid.org ) back in 2000 and was first entrant into the market. Composite Software soon joined ranks of EII vendors and quickly established itself as a fierce competitor. MetaMatrix was acquired by Red Hat in 2007.  Red Hat initiated the process to open source the MetaMatrix software as it does with all acquired code that's not yet open. The Teiid community project was born out of these effort in January 2009.  On the path to open source, we took the opportunity to step back, re-evaluate and

Planning to Migrate Your Relational database to MongoDB?

Are you planning on migrating your relational database data in Oracle, MS-SQL, MySQL, DB2, PostgreSQL etc., into MongoDB for scalability and performance reasons? Or you want to use MongoDB for your new project, but not do not want to spend too much time learning MongoDB APIs? However, you are a seasoned SQL developer? Or you have data in databases, CSV files and other applications that you need to integrate together and store in MongoDB and do further analysis? If "Yes", please keep reading... If you have previously attempted at migration of data yourself, I am sure you may have come across these below links before. http://docs.mongodb.org/manual/reference/sql-comparison/ http://docs.mongodb.org/manual/reference/sql-aggregation-comparison/ http://docs.mongodb.org/manual/tutorial/model-embedded-one-to-one-relationships-between-documents/ http://docs.mongodb.org/manual/tutorial/model-referenced-one-to-many-relationships-between-documents/ http://docs.mongodb.org/

Expose Excel Data as OData feed using Teiid

For that matter you can expose any data source that is supported by Teiid through its translators as OData service. You can convert Relational databases XML, JSON, CSV files Web Services  Sales Force Excel documents sources, or write your on top of your specific source. Teiid added support for exposing its virtual database (VDB) as OData service without any additional work. Create a virtual database with your required sources and create any additional views and deploy in the the JBoss EAP 6.1 server, that has Teiid 8.3 or greater installed.  See https://docs.jboss.org/author/display/teiid84final/OData+Support  for more information. So, lets build a simple example of exposing the Excel Sheet. Teiid accesses Excel sheets via JDBC-ODBC bridge, and Windows OS provides a ODBC driver for Excel documents.  Edit the standalone-teiid.xml, and create Connection Factory jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};Dbq=c:\ODBC\ExcelData.xls odbc

Scrollable results will have only a marginal improvement. TEIID-2427 TEIID-2311 Column Masking added column masking and refined row-based security. Also allow for permissions to be granted via the MetadataFactory methods addPermission and addColumnPermisison to enable adding roles via a MetadataRepository. Additional web service security features and mongo connectivity have made it into 8.4 and will be fully doc'ed and in the release notes by the next CR/Final. If needed we will produce a CR2 in approximately 10 days and will generally be selective about what issues get released before the Final.  Beyond the 8.4 Final we now have the 8.4.1 and 8.5 release version targets active to take additional issues. *And now more on

Teiid 8.4 Beta2 Posted

Teiid 8.4 Beta2 for EAP 6.1.Alpha is now available in our downloads .  The new features in this beta (since Teiid 8.3 Final): TEIID-2444 EAP Platform - the deployment platform for Teiid has been changed to EAP 6.1.Alpha1 TEIID-2429 Improved sort performance - improved sorts for large data sets especially under heavy load.

TEIID-2344 Automatic DB Version Detection - the JDBC translator database version property in most circumstanc

Teiid Designer 8.1 Final Released

( download/install ) Key feature for this release is providing the ability to develop and test your VDBs against both Teiid 7.7 and Teiid 8.3 runtimes (JBoss AS 7.1 and AS 5.1 platforms).  This feature allows managing your older VDB artifacts with latest tooling and provides a mechanism to migrate and test your data services on the newer server version. Other features include: New relational object wizards (Table, View, Procedure, Index) Improved synchronization of workspace models with VDB artifacts Multi-source binding support in VDBs ( TEIIDDES-472) (See also TEIID-2253 Multi-source improvements ) New model importer using deployed data source through Teiid runtime ( TEIIDDES-1575 ) For more details, check out What's New !

(Teiid 8.4 + EAP 6.1) Alpha

Teiid has been using JBoss AS 7.1.1 as deployment server for last few versions. We wanted to move to later versions of the JBoss AS, but no JBoss AS community versions released after 7.1.1. Then JBoss EAP came along... Teiid 8.4 Alpha1 is our first attempt to make Teiid deploy using EAP 6.1 Alpha. Even though EAP 6.1 Alpha , has a tag of "Alpha" this is much more stable version of the JBoss AS (7.2.Final). If you are concerned about licensing issues with EAP 6.1 Alpha, please see this thread . The installation is same as before, download the EAP 6.1 Alpha and then Teiid 8.4.Alpha1 and unzip the contents of Teiid archive over the EAP's directory. One notable change you will see is, how Teiid deploys the resource adapters in this new version. Instead of deploying them as RAR files, they are now deployed as the JBoss Modules.  You can still use the RAR file deployment as before,as there is no changes there. Take it for spin and let us know if you find any issu

Teiid 8.3.0.Final Released

It took us little more than 12 weeks from 8.2 Final, however Teiid 8.3.0.Final is released with many many exciting features. The features we really excited about are OData Support - Teiid can now either consume from a OData source or produce results using OData protocol. See related blogs on this topic. JSON Support - Similar to how user can use SQLXML and define results in XML, Teiid is introducing JSON  language constructs, such that you can produce results in JSON. Now you can generate that Rest web service that returns JSON!!! Source Temp Tables - create a temporary tables on sources, and generate plans that are efficient in pushing down more work towards the sources. Many more.. See below for full list Teiid 8.3 is still based on JBoss AS 7.1.1   The JBoss folks have decided not to release any community releases off of AS 7.x branches, however they recently announced   that EAP 6.1-alpha1 (a productised version of JBoss AS that RedHat offers subscription) is releas

Teiid 8.3 CR1 Available

Teiid 8.3 CR1 has been posted to the downloads .  The new features since beta2 include: TEIID-196   Source Temporary Tables   - temporary (locally scoped) tables may be defined at runtime against physical sources with a CREATE FOREIGN TEMPORARY TABLE statement. See the Reference for more. TEIID-2159   JSON Production   - added the JSONARRAY, JSONARRAY_AGG, JSONOBJECT, and JSONPARSE constructs for producing JSON. See the Reference for more. TEIID-2248   Bulk Salesforce Inserts   - added the ability for the Salesforce translator to perform bulk inserts. We've been getting great feedback on the beta releases, which has led to several important fixes - so keep up the good work with the CR!  Be sure to contribute any documentation or Javadoc updates that you see are needed as well.  8.3 Final is on track for 2 weeks from now so now is a great time to help shape the 8.4 release. Steve

Integrate OData Source Using Teiid

Teiid 8.3.x release has a new translator "odata", that supports consuming of OData sources. Using this translator a user can integrate data from a OData source with other sources in Teiid. If you like to know what OData is and Teiid support for it, please read this previous post http://teiid.blogspot.com/2013/02/odata-support-in-teiid.html In this blog, we will write a Teiid VDB, that shows how to consume a OData source, and how Teiid uses OData's CSDL metadata document to expose it in relational form such that it can be integrated with other sources. So, let's begin.. In a Teiid system, OData translator is a extension of the "ws" web services translator, since all OData queries are REST based web service calls, and results are published in "atom/pub" or "json" format, it uses the same resource adapter "teiid-connector-ws.rar". For this example, we will use a example OData service at http://services.odata.org/Northwind

Access Teiid from node.js

Are you writing a "node.js" application and would like to access Teiid VDB from it? If "yes", this is currently possible using NPM package "pg" .  Since, Teiid supports the PG transport, you can use this PostgreSQL client for "node.js" for accessing the Teiid. For example if you have VDB called "northwind" deployed on your Teiid server, and it has table called "customers" and you are using default configuration such as user = 'user' password = 'user' host = 127.0.0.1 port = 35432 then you can use following to write simple access program to Teiid var pg = require('pg'); var connectionString = "pg://user:user@localhost:35432/northwind" pg.connect(connectionString, function(err, client) { client.query('SELECT CustomerID, ContactName, ContactTitle FROM Customers', function(err, result) { console.log(result.rows) }); }); If you want

OData Support In Teiid

What Is OData? "The Open Data Protocol (OData) is a Web protocol for querying and updating data that provides a way to unlock your data and free it from silos that exist in applications today. OData does this by applying and building upon Web technologies such as HTTP , Atom Publishing Protocol (AtomPub) and JSON to provide access to information from a variety of applications, services, and stores. The protocol emerged from experiences implementing AtomPub clients and servers in a variety of products over the past several years.  OData is being used to expose and access information from a variety of sources including, but not limited to, relational databases, file systems, content management systems and traditional Web sites. " - taken directly from http://www.odata.org  OData is specification from OASIS committee, and this specification is backed by Microsoft, SAP AG, IBM, Citrix, Progress Software and WSO2. Why y

Teiid 8.3 Beta2 Posted

Teiid 8.3 Beta2 is now available in our downloads .  The new features in this this beta: TEIID-2363 Concurrent Join Processing Enhancements - both sides of a join will processed more when possible. See also the org.teiid.joinPrefetchBatches system property in the Admin Guide. TEIID-196 Source Temporary Tables - temporary (locally scoped) tables may be defined at runtime against physical sources with a CREATE FOREIGN TEMPORARY TABLE statement. See the Reference for more. TEIID-2159 JSON Production - added the JSONARRAY, JSONARRAY_AGG, JSONOBJECT, and JSONPARSE constructs for producing JSON. See the Reference for more. We are on track for the first candidate release in two weeks.  Looking ahead we'll be creating an 8.4 release target and should begin work on a 9.0 release by the end of that cycle.  Of course any feedback on the 8.3 release before final is greatly appreciated. In addition to the AS Teiid Web Console management option, an initial plugin binary for RHQ

Teiid 8.3 Beta1 Available

The march toward 8.3 continues with Beta1 now available in our downloads .  Over the last alpha this beta features: TEIID-2182   Events   - Capture the VDB loading and unloading events now from registering a listener on EventDistributor TEIID-2241   CLI script for Standalone   - Install Teiid into any AS7 standalone configuration using the provided CLI script. TEIID-2152   Basic MERGE support   - support for a simplistic MERGE statement was added. See the Reference for more. TEIID-1757   OData Translator   - A translator for OData based sources has been added. TEIID-1854 and OData support in general is progressing nicely - there will be more on this later in the release.  There has also been lots of important fixes so this should be a good pre-release to take for a test drive and provide early feedback. The 8.3 development cycle will be extended slightly beyond the normal quarterly window due to the slowdown over the holidays and to accommodate getting a few more features co

Planning started on Teiid Designer Komodo release

With the changes in Teiid 8.x coming on-line and the use of Dynamic VDB's in Openshift becoming more visible, it's become apparent that Teiid's primary tooling, Teiid Designer, should re-visit it's architecture and embrace these concepts. A few discussions have already occurred amongst community members and a release code-name Komodo (a type of lizard akin to Teiid, the whip-tail lizard) was adopted to identify the next-generation Teiid Designer for the time being. Options for incorporating elements of Teiid's new direction could be accomplished through drastically modifying/removing Designer's current underlying EMF framework and developing anew from a fresh user perspective. In addition there may be benefits to creating a tighter coupling between Komodo and Teiid runtime, as well as incorporating other JBoss technologies/projects like ModeShape and SRAMP work being done in Overlord. A summary of the discussions that have taken place and links to ap

Hello 2013 - Teiid 8.3 Alpha2 is Available

8.3 Alpha2 is now available in our downloads .  This alpha features: TEIID-2311   Permission Conditions   - data roles can now specify SQL conditions that will enforce row-based security and physical table insert/update checked constraints. See the Reference Guide for more. TEIID-2341   Join Planning Improvements   - ANSI join structures can now be preserved with the preserve hint, i.e. FROM /*+ PRESERVE */ (tbl1 INNER JOIN tbl2 ON ...), which is similar to the Oracle ORDERED hint. Also sources restricted to only outer joins can have INNER or effectively INNER joins pushed to them. TEIID-2312   Source security domains   - Ldap, Salesforce, google-spreadsheet and ws (basic auth) translators can now define "security-domain" in their resource-adaptor configuration for security. When defined along with caller-identity the logged in user's credentials are passed to source for authentication. TEIID-1854 also had it's initial commit, which will provide Teiid with the
