We have a python based server that uses mongodb database. Our server programs uses RabbitMQ to exchange request/reply packets with many Android apps and perform actions accordingly. In addition to this, now we also need to create a web portal for the admin staff to let them manipulate the database, upload/download files, view data/statistics and trigger actions for android clients. So, the database is going to be common for the portal and the existing server programs.
For the web portal development, I got a recommendation for using Plone. We are comfortable in using traditional Node.js. Could anybody guide me on the use of Plone within this context. Is plone able to communicate with mongodb and existing server side programs?
Plone is a CMS designed around managing web based content and is tightly integrated for storage of its data in the ZODB, a NoSQL database. If data is very custom and isn't all about webpages and website nagivation etc, or if you have a need for the data to live in a different kind of DB then Plone probably isn't the right tool for you. This isn't to say it can't be made to do these these things but you would have to learn a lot about it's internals to make it do these things.

I want to add the feature of database synchronization to my project. It should be like this:
When the internet connection is available the application should transact with the online database server.
When the internet connection is not available it should keep track of the transactions and should update the local DB to online DB server when connection is available it should synchronize.
How can I do this?
Before that we are using Multi Tenant concept in our web application. Single online DB can access all clients using multiple schema.
I want to know how can my web application work in offline mode. If I use HTML5 application cache concept means the HTML and CSS file will load from cookies. How can I get the database value from database when application goes offline.
What is a good way to make my application work online and offline with database?
Most modern browsers have databases or persistence facilities similar to a database for pretty much exactly this use case.
You may end up having to dive pretty deep into javascript to get it to work though. (Especially when the online DB comes back online and you have to go back through all the offline data and send it up (post) to the server end)
I've been looking all over the web for a solution to a client problem. They refuse to retire their 16-bit dbase database, but still want us to development real-time PWA web applications to read/write to the dbase system.
If it is even possible to get a RESTful API server working with 16-bit dBase?
Yes. You can create a PWA app with dBase or any DB, which has option to communicate to modern programming languages via APIs like JDBC, ODBC. Then that programming language of your choice, say JAVA talking to dBase via JDBC, can expose the functionality via RESTFul service.
For a PWA app, underlying back-end service tech stack is masked over plain HTTP requests. So it doesn't matter what back-end service you use and what DB that talks to in turn, for a PWA
As an update on your “real time “ need, not sure what kind of real-time functionality you are planning and on expecting what ETA/SLA. While no doubt you can build a PWA with any dB as stated above, it can certainly impact its performance. If you need something like googles auto suggest which pulls up results as you type, you need something like “in-memory” DB.
So the question is more of what performance your DB can support and what is expected. I do not see any feasibility challenge with respect to PWA.
I want to develop a website that will serve millions of pages everyday including the mobile devices. Site will have strong social features and thus would require lots of reads/writes. It will also suggest things to users based on their social behaviors (likes, dislikes etc) and their friends' behaviors. After considering many elements I have come up with
NoSQL (MongoDB or Cassandra) Database. Not sure which one is the right one.
memcached
Varnish or squid for http acceleration
php and python (Not sure if php is that scalable)
nginx or Apache web server
Any recommendations?
There are NoSQL databases that has an integrated web service that can handle much more web requests per second (including database transaction time) compared to traditional web services requesting data from an external data source. Using this kind of solution increases the performance, save a lot of time in implementation and simplify scaling your website.
The recommendation depends on how you plan on implementing the solution: a server side rendering solution or a client rendered solution? Will you have any MVVM style implementation making the communication talkative? Also what server side environment do you have in mind? Microsoft/Linux?
Take a look at Starcounter database that has a web server component integrated into the database engine and see if that could help you.
In search of a 'Cloud Content Management System' like http://osmek.com/,
I could not find a single other CCMS that does what I want it to do :)
Basically, what I need is content management without a website frontend attached.
Just basic storage of data, documents, images, etc. etc. with a simple API to access, like Osmek. Just NoSQL or SQL based services won't do, because there can be images or documents attached. And, ofcourse, I'd like to have a backend to manage the data (like a typical CMS does) without writing a backend myself (if it's just the service)
Osmek is great, and it works most awesome in conjunction with Actionscript 3, but I'm just looking / searching for alternatives (if there even are any yet).
I need this form of hosted content management for content-manageing a mobile application.
So the question is: Is there anything else out there that does the same as osmek that you know of? OR, how do you manage application specific content?
Thanks!
I'd encourage you to take a look at Cloud CMS (http://www.cloudcms.com).
Cloud CMS is a JSON content management (CMS) platform built on top of MongoDB with a REST API and drivers for a variety of languages. You just drop in a driver and call methods to query, create, update and delete content.
The platform provides everything you need to power the back-end for mobile and HTML5 applications - from managing your content to managing users and groups, credentials, security tokens (OAuth2), Git-like collaborative workspaces, real-time analytics, activities, data transformations and more.
Everything runs in the cloud on an elastic back-end. It's probably more akin to Parse than a traditional CMS. You just make calls to the APIs. We keep the costs low by letting you only pay for what you use (almost like a utility). You just pay for storage and data transfer.
Disclaimer: I'm one of the founders of Cloud CMS. So I'm a pretty lousy reference in terms of its objective value. However, a couple of us worked at traditional "ECM" companies in the past and we think we've built something that puts a genuine beating on those guys.
I wanted to make a web application through which :
user(end user) can create his own
web application online.
which will be integrated with the
databases and application/web
servers
and user can also publish that
application withing that application
only...
Doing some research i come to know it goes under category of PaaS(Platform as a Service)
But i am confuse how can i do that ?
I want to build that application using Java/J2EE.
Can any one explain me from where should i start ?
Or which framework / technology is better to implement it in Java ?
Waiting for your helpful reply....
There are several options as far as choosing a PaaS - each PaaS vendor has its pros and cons, so you need to consider a range of issues:
Language support - Do you want just Java or maybe additional languages/frameworks?
Hosting - Are you going to use a cloud computing provider like Amazon Web Services? Or are you using your own hardware? Or do you want multiple options?
DB support - You mentioned using a central DB. Do you plan on installing/administering this DB yourself, or use a hosted DB service? Do you need the PaaS to support the particular DB you want? Perhaps you need multiple Databases to provide scalability and separation among clients?
There are several good comparisons of PaaS vendors out there. This might be a good place to start: Looking for PaaS providers recommendations
Full disclosure: I work for Cloudify, an Open-Source PaaS provider.
I think while choosing a PaaS you should think of the below points.
It should be easy to deploy, scale and manage
Scaling
Flexible topology
Data safety
No vendor lock in
Open software stack
I suggest you, before going to any big vendor try a new player in town Jelastic. I recently used their services and continue to do so and they are just awesome. Their web UI is best in class and has no drama of API, SDK or downloadable software. Let me know if you use them so that I can also have some feedback before I migrate all our apps to them.

As far as i understand, you are looking for a solution that Viravis is currenlty implemented.
But believe me it is not an easy task to build that kind of platform. i strongly suggest you to look at some PaaS providers to get involved and build a business relationship to achieve your goal. They are just exists for this purpose. Provide platform for people who just want to develop a single online application or some professional who want to build an SaaS business.
I think it is better to hire the platform rather than build it from scratch (ofcourse if you dont have to...)
A web application consists of language, framework, database and Web-server.
If you want to make a web application in java, you should try GRAILS framework.
Its fast and web development is very easy and you can use java code as it is, in it.
Secondly you can choose database from MySQL, PostgreSQL etc or if you want to use No-SQL dbs, you can choose from MOngoDB, CouchDB etc.
Web-Servers can be tomcat, jetty etc.
After creating you application, you would like to host your application on web, Here PaaS comes to play. It helps you to deploy and host your application on web. So what you have to do is only to focus on your application and then deploy your app on any PaaS providers.
There are many PaaS providers in market, you can choose any.
