I have medical data.
I want to prepare a case study and insert these medical data into corda platform.
How can I insert data into corda software?
I installed Corda Demo Bench software but it does not have such functionality.
Technically, Corda is not a software that you can just "insert" data and use. Corda is a platform that has applications sit on top of it. That is, you need to build your own Corda application to suit your business uses.
And the data part that you are mentioning will be the State in your Cordapp. More information can be found at https://docs.corda.net/key-concepts-states.html
If you are looking for a ready-to-use solution, R3 has a Corda solution marketplace #https://marketplace.r3.com/dashboard

We are working with a client who is interested in developing a application using Corda Ledger. While in the initial phase of development to first rollout in to Production, client is looking to see the capabilities of Corda Ledger using its community version. Subsequent to first Production rollout when the capabilities of Corda are on the display with its own client, they want to look beyond making this solution a enterprise solution using by procuring Corda enterprise license.
I am not getting much help in forming a delineating line of difference between Community and Enterprise version of Corda.
**What are essential features which cannot be built using community version ?
**who governs Community version ?
**Is there any support provided for Community version ?
**Can we create a distributed architecture using Community version (Corda nodes located on different physical servers) ?
**Can we create Corda network using Docker containers using Community version ?
**Is there any detailed document to draw the lines between community and enterprise version ? **
I have worked on community version of Corda using it for developing PoC, Where all nodes are located on same server and were not truly distributedstrong text
Corda Open Source and Enterprise are functionally identical. What Enterprise offers extra is the non-functional stuff that is required for mission-critical enterprise applications, which includes performance, HA, HSM integration, Enterprise Database integration, 24 X 7 Support, etc.
The community version id developed primarily by R3, while we also accept and encourage community contribution to the Corda Open Source project.
There is no Official R3 Production Support for Open Source Corda, however, you could ask questions and ask for solutions to your problems on our public slack channel (stack.corda.net) and also here on StackOverflow.
You can operate a network of OS Corda with nodes on different servers without any problems.
Could somebody Corda Enterprise edition license model and cost? Like whether it is per user/node basis and monthly or yearly etc.
I looked at 'https://www.r3.com/corda-enterprise/' but didn't find the licese cost info.
I saw that enterprise edition also open source and code is available on Github.
Thank you.
You should contact R3 directly (sales#r3.com) for pricing information.
According to R3:
The platform is scalable and priced according to the specific needs of
the business. There are many considerations around product,
architecture, geography and customer profiles, which influence this
analysis.
I am planning to use Titan Graph DB for my project.
The reason for selecting it is because it is the only graph database which can use DynamoDB as the storage backend. Thus I can free myself of the scalability/throughput worries.
But when I am trying to find any tutorial to get started with Titan, I am not finding many of them. This makes me doubt whether to use Titan or choose another graph database, like Neo4j or OrientDB.
Can someone tell me if Titan being used widely?
Is the community active?
Can I expect proper releases?
The last blogpost on ThinkAurelius is dated Feb 3, 2015 regarding acquisition by DataStax. DataStax website has no mentioning about Titan.
Your question is more of an opinion question which might be suited for a different forum, but I will attempt to answer the main questions you stated anyway.
Is Titan being used widely? This is hard to tell since Aurelius doesn't disclose much information publicly about their users other than their client list. The Amazon Fulfillment gave a session on their usage of Titan with DynamoDB. This blog post identifies NASA's Jet Propulsion Laboratory and AdAgility as users also.
Is the community active? Somewhat. There are discussions occurring on the Titan mailing list and new messages come in every day. Commits are being made on the titan11 stream in GitHub. The most recent commit was on April 4, 2016.
Can I expect proper releases? "Expecting" releases of software is not something I would recommend in general. Software (both open source and proprietary) is released when the maintainers think the code is ready. For Titan specifically, the core maintainers have largely been absent from the community because they are busy working on DataStax Enterprise Graph.
I've seen this question but the answers are simply not good enough. I've searched the web and could find a clear listing of the main differences.
I am particularly surprised to see contradictions in the above link, that holds only 4 short answers.
So the question is, beyond support, what are (all) the differences between Alfresco Community and Enterprise editions (for the current versions of course)?
Are there functional or technical features that available in the Enterprise edition, that are not in the community edition?
I find it strange that it's so difficult to get a clear list. Looking at the forums to find this answer is not a serious option from a business perspective.
Until now, I found this link to be useful, but it's from 2009.
In particular, I find the platform support interesting, with the community edition supporting only lamp stuff:
Linux
MySQL
Tomcat
OpenLDAP
Firefox
And the enterprise edition supporting:
Windows
SQL Server
WebLogic, WebSphere
AD/Kerberos
IE and Safari
Apparently, these features are only available in the enterprise edition:
JMX monitoring
Runtime admininstration: What's that exactly? And what's in the community edition then?
Runtime indexing consistency check and update: What's in the community edition then?
High performance and availability: How is that implemented and what's in the community edition then?
Storage policies
Open source and proprietary technology stack support: which ones exaclty? Which ones are supported in the community edition?
If anyone could guide me towards serious documentation about these differences, that would be great.
I also went through the wiki but could not find an answer to my questions in there.
differences between Enterprise and Community vary in detail from version to version and are mainly visible for administrators. We see or maintain both flavors of Alfresco in midsize to very large environments and I would say it's more or less a question of taste and budget what the best decision / edition is for you. Excellent skills in infrastructure and java are highly advisable for both editions to run Alfresco in production.
The technical differences are not as dramatic as not being able to provide very similar functionality for the users - so if you're actually in a decision you should focus on a good technical partner, the support services and maybe the fact that you only get official patches in the Enterprise subscription, not on the Community. BTW Alfresco Enterprise is not Open Source but this is not a real point of interest for most end users. You can access the code as a subscription customer but it is not public available/accessible.
The main differences in features are already named more or less:
Administration
Enterprise has more views and setting in the admin web GUI. In Community you can access most configuration only from the command line. This may be a restriction but in real live Administrators prefer the command line and scripting automation.
Enterprise lets you change some Alfresco settings during runtime (most settings still require restart). Some can be change in the GUI and more in the jmx interface. Also you're able to stop and start subsystems like the CIFS protocol server. We use this feature to switch a system in read only mode. This point is meant with "runtime admininstration". Community requires restart of the service for most configuration changes. It is possible to work around this by advanced scripting like groovy or by implementing modules.
Indexing
Runtime indexing consistency check and update is not a self healing functionality as expected. You will have to learn (at least for now) that you have to recreate the Alfresco index from time to time even in Enterprise environments and that it is better to focus on good strategies how to speed recreation or how to setup standby indexes instead of hunting failed indexing transactions using the check and update methods. For major document model changes you need to recreate the index anyway.
High performance and availability
This is mainly the cluster and replication functionality which is no longer available in Community. It's similar to MS Clusters: It's a lot, lot work for very view more availability since some concepts are missing. The price is high in terms of complexity and can end up in loss of robustness. Even with enterprise support it's a hard job to keep a alfresco cluster running - so you need very good arguments why to go this way. But of course: its possible and available!
High performance: There shouldn't be any difference and if - I'm very curious about the explanation.
Technology stack
The main difference is the database support. In the Community you only can choose between MySQL and Postgres (No Oracle or MS SQL for Community). All other technologies are independent from Enterprise or Community (AD, Kerberos, OS, Browser, ...)
Java Container: I believe over 95% of all Alfresco installations run in tomcat. That's the configuration which is documented, tested and scales. Using WebLogic or WebSphere gives you no added value except new challenges - quite the contrary: You have to solve most issues for yourself and can't benefit from others experience.
Storage policies: I'm not pretty sure and should check in 4.2.x if the Content Store Selector / Storage policies is no longer available in the Community, but it was there in the 3.x versions.
[Edit]: storage policies have been removed in Community 4.2.x:
NoSuchBeanDefinitionException: No bean named 'storeSelectorContentStoreBase' is defined
If there is a really need for this functionality someone may re-enable that feature by coding a module for Community.

This page explains the difference between the editions:
https://wiki.alfresco.com/wiki/Enterprise_Edition
This page is the canonical, comprehensive list of the differences.
If you are considering an Enterprise Subscription and you have a question that isn't answered by what you can find on that page, you should talk to your account rep.
Well, regarding JMX monitoring:
Runtime administration: Alfresco enterprise allows to perform certain actions on Alfresco subsystems without restarting the server. This allows you to be very fast during debugging/developing and also making changes in production environment. Also you can access the JMX interface that supports JMX Remoting.
There is no consistency check or update, until you restart the server (during the startup you have to validate/check/rebuild your indexes). There is an option in alfresco.global.properties (or the original repository.properties config file) for that. If you have some inconsistencies in the Alfresco Community index, you're gonna have a bad time xD.
Alfresco Enterprise has specific license for clustering your architecture, the Community edition doesn't support those systems. Replicate and cluster Alfresco is one of the main improvements in performance/scalability/availability you could achieve.
The storage policies allow you to use Content Store selectors in Alfresco Enterprise. You can manage a primary and a secondary file store, and map/connect these stores in your architecture. The Community Edition allows you only to use one content store at a time.
These include everything inside Alfresco (Spring Framework, Apache-Lucene/Solr, Tomcat, and so on), because with the Enterprise license you have also the full support with everything inside the Alfresco package. The difference is that the Community is based on daily builds, supported by community, and therefor not guaranteed. The Enterprise support helps you resolve many problems that you might encounter during developing and in production environment, not only Alfresco related, but also on some configurations on supported platforms (Windows/Linux), your web application servers, and so on.
Hope it helps.
Can somebody provide real world examples of software products or applications (commercial or open source) that have SOA in them?
Like for example some X company claiming that the latest released version of their software product is now SOA compatible.
SOA is not a specification that a software product could be claimed to be SOA compatible. Read more on what SOA is at http://en.wikipedia.org/wiki/Service-oriented_architecture
SOA is basically an architecture/implementation technique which aims towards loose-coupling of the presentation layer with the data layer. Thus, multiple services/modules/applications could access the same data and use it as per their need. This loose-coupling can lead to more of distributed programming. The day you see that a particular service is more in demand, you could add nodes to your cluster for the particular service.
Examples per se would be applications that were build with SOA architecture. Liferay (an open source Java CMS) is a service-based application. All application that expose some sort of an API (see programmableweb.com) can be termed as SOA-enabled where in you pull data and consume it the way you want.
But yes, for sure, SOA is not a specification.
