I am having a requirement that i want to inserted the record into COUCHBASE using UNQL,Can any one suggest me how to connect COUCHBASE using UNQL.
Regards
Pradeep
Unql is an open project and a preview intended to help discussion on use cases for a query language with these newer databases. It's not included in any release of Couchbase at the moment.
See couchbase.com/develop for info on how to insert data, etc.

My company runs a huge Lumen 5.1 project on MySQL. They want to add to it analytics, and they that part to use MongoDB
Is it possible to use MongoDB without any third party libraries? I one going to use
https://github.com/jenssegers/laravel-mongodb
But the tech lead thinks Laravel support MongoDB by default, I'm just asking this question to check whether that's true or not.
Edit:
If MongoDB isn't an option, does Laravel support any other NoSQL by default?
Laravel does not support MongoDB by default.
You would need to use one of several available third-party packages. I like moloquent because it maps mongo db collections to laravel models just like eloquent.
You can use Redis if you need a natively supported NoSQL db or could consider ElasticSearch (not supported natively) if you are going to store a lot of meta data and then analyse it. Tools like kibana and logstash might get very helpful.
Just making sure, does Spring Data Cassandra support #PrePersist? I did not find anything about this in its manual.
Not at this time. Issue is at https://jira.spring.io/browse/DATACASS-106.
We have an EZ Publish 5 already operational with an Oracle 11g database as a persistence backend.
We planned to get rid of Oracle and we know that we could use Postgresql for sure as a new RDBMS, but we also planned to use MongoDB whenever it's possible.
So the question is: Can we pair EZ Publish 5 to a MongoDB NoSQL database ?
Quick answer: You cannot now as there is no MongoDB driver implemented.
There was a NoSQL Driver planned in the 5.x series, but it is not yet implemented in the latest eZ Publish 2013.06.
With the official roadmap not being updated since the 4.6 release, it hard to guess when the NoSQL driver will be implemented, and if MongoDB will be supported.
Theorically, as the new persistence API make it "easier" to add new storage drivers, you could write a custom MongoDB storage driver.
But in practice implementing a storage driver is quite complex and resource consuming.
Contacting the eZ Systems office in your region and directly ask them when a MongoDB driver will be available might be fastest way to get a clear answer.
I hope it helps.
It is not currently possible as there is no storage engine implemented for MongoDB.
It is indeed planned to implement a NoSQL engine, but there is no version tag on this for now.
However, the new persistence API makes it possible to "easily" implement such a storage engine, but you will be limited by the fact that eZ Publish 5 still uses the legacy back office which runs in the legacy stack (so with 4.x infrastructure which is not compatible with NoSQL).
In short: Implementing a new storage engine will make it only accessible from Public API and REST API.
Since ez5 is a symfony application you can achieve this the symfony way
http://symfony.com/doc/current/bundles/DoctrineMongoDBBundle/index.html
just remember they have renamed the app folder and the appkernel.php.
Haven't tried it yet though
I have to create an Xpage web application which directly inputs data in a PostgreSql database. I've never worked with a PostgreSql database so I have absolutely no idea on how to approach this.
The application will be used through a browser if that matters.
Any help would be highly appreciated.
or, if you do not want to use the extLib for this purpose only, take a look at http://www.eknori.de/2011-07-03/using-mysql-data-in-xpages/ The article describes, how to access MySQL, but you can use the same code even for PstGreSQL with the correct JDBC drive.
The article also contains a link to OpenNTF where you can download the full source code.
You need to use a JDBC connection to connect to PostgreSQL. Use the extension library. This library contains a demo application which connects to a sql database using JDBC. Please take a look at this question : How do I access SQL from XPages.
Any API for this?
What about query with conditions on key or values ?
I know there is a tap.py, which can dump all contents from Membase, but it it just a tool.
There isn't a way to do this do this Membase, but Couchbase 2.0 will add query support and will be released in late October. In the meantime you can download a developer preview on the Couchbase website to check out the new features.
