I have a question about mongodb. Indeed, I want to switch from oracle dbs to a mongo db in order to have more flexible structure. The goal of my project consists in carrying out some consistent data analysis after implementing a mongoDB which will able to store my data in json format for instance or some useful logs about requests done by my colleagues on a Web service.
Please, what are your tips ? What are the most efficient java frameworks in order to build a solid database ? Need I to learn some other languages ?
Feel free to suggest or to give me our advice on who to start properly with this tool. Any share of your feedback on your experiences with data analytics for BI will be a real pleasure for me.
Thanks... :)

I want to start a project on Laravel and want to go for NOSQL. I need extensive search with this project and was considering Mongodb but I am not sure about search.
Few related questions:
Is there enough support for using NOSQL, incase I get stuck somewhere?
NOSQL is flexible enough for searching parameters?
If I need to import data from previous project to NoSQL will it be a challenge?
What about realtime time, does NOSQL supports realtime?
Thanks in advance.
I have to develop a web application (for Healthcare sector) in python using a Big Data platform (NoSQL Database, like Elasticsearch for ex.)
I want to know, what is the best Big Data platform for this situation ?
Could someone help me ?
You need to do an evaluation of NoSQL databases. Like write down the features you need or how much you need them, examples how you want to access or fill the database, and then try out several noSQL databases how they perform or how you can work with them.
There is no "best" noSQL Database.
We have an existing system using Oracle DB and several applications working on/off it using JDBC/ODBC etc. For an additional interface for CRUD operations I am looking at a web based front-end. I dont see a whole of ideas in this areas, maybe because the ORacle DB is mostly enterprise and probably means the enterprises building their own custom apps?
Using the Oracle REST API services, build a front end using Angular/JS. This eliminates any need for oracle specific server side logic and almost ORacle independent. Are there any frameworks / opensource tools that fall in this area?
Please let me know any comments / feedback on this approach.
As far as I know there aren't really any options like this specifically for Oracle databases. You might be better off going with a desktop solution, of which there are many.
There is a web UI called "H2 Console" which claims to work with any JDBC connection. I have used this with MySql before with great success but have not tried it with Oracle.
The H2 Console application lets you access a database using a browser. This can be a H2 database, or another database that supports the JDBC API.
If you want something more 'user friendly' then as far as I know there are no existing solutions for this. You will probably have to build your own or educate your users on SQL.
Ok, so, I'm developing an app and I'm using Cassandra as the database.
Everything going good so far, but now I need to do a query using the LIKE clause.
I know Cassandra doesn't support that, and that's why after looking for a workaround I was thinking in maintaining this single table that I need to query using the LIKE clause in another database, other than Cassandra - was even considering a relational database, even though there wouldn't exist any relations.
Then I started looking to see if this is really the right approach, and came into stuff like Spark, Sorl and ElasticSearch.
Just to make it clear: I have little to no knowledge about those frameworks. Really. I only have heard about them and that's all.
So, I'm not here to ask you guys 'hey, how to do that using this framework?'. I just want to know, before I dig into any of those: Would any of those satisfy my needs? - Since I have no idea exactly how they work, and what exactly they are for.
If it is the case, them I'll study the framework properly - I just don't want to spend the time to figure out it has nothing to do with my problem.
Thanks!
Both elasticsearch and solr fits your needs. They use lucene library to perform reverse indexing and much more -- Datastax enterprise (commercial distribution of Cassandra) offer this solution integrating solr natively. One more solution (little different but working) is to integrate infinispan which offers both integration with Cassandra repository and reverse indexing ...

I learned to love how LINQ enables set operations on collections. I'm not saying that I plan to shun traditional RDMBS, because I do need it for reporting. There are NoSQL alternatives out there, but they seem to all need to fire up a separate service.
What I looking for is something local where a DLL can create a database and perform CRUD on it. As mentioned, I'm not going to report out of this, just internal data store. The main application that will be using it is in C#.
I'm hoping that someone can give me a lead. If not, if there is anyone willing, we can start a open-source project for it. I'm not interested in commercial products.
Thanks,
You can run RavenDB in embedded mode inside your .NET application - no need for external services or anything.
And RavenDB supports Linq....
