I am a new developer using Couchbase Lite in iOS with the language Swift. I've read the documentation multiple times, however, I am still left confused on how to take advantage of views and queries. I have found one resource, Pro Couchbase Server, which only provided one minimally detailed section on Couchbase Lite for iOS. Are there any resources, other than what I have mentioned, for understanding how to properly structure views and make complicated queries?
They Couchbase Mobile Developer portal is a great resource for learning about Views and Queries.
And can look at the Couchbase Mobile forums for other specific questions too.

Can anyone advice if is it possible Sitecore would work with Oracle Commerce/ATG 11.3 and Endeca?
There is no reason why it can't be integrated, it depends how deeply you want to integrate it. For example SiteCore exposes a RESTful API that allows you to get to individual content items.
Since you mention Endeca as well, I assume you want to be able to index the content too? For that you will probably have to develop your own CAS connector, potentially hooking in to the SiteCore search functionality.
There may be other APIs to hook into as well but since your question is whether it is possible. The answer is still 'Yes'.
As for whether it is the right solution, that is a different question. What does SiteCore give you that the BCC doesn't? Can you migrate from SiteCore to the BCC? Does SiteCore expose other APIs that will allow them to be 'read-only' stores in an ATG application (BCC or Storefront)? Many options exist.
Hi i am developing a metro style application where i will be connecting to web services and get the data from the web service and i will be binding it to the UI.
But my requirement is in my application i need to create tables and also provide relation between the tables and dump the data in to that local database and use that data in calling the other methods present in my service application (calling one more method in services by passing something as an input to that).
Can you please explain me the following :-
What is Database which is supported for metro style apps?
How can i create a database and create tables and dump the the data which i got as the response from my service application?
I am new to Metro style application development please help me out .
Thanks in Advance.
First of all WinRT has very poor db support. Most of this kind of things are done by web services, OData etc
BUT I`m almost 100% sure that you can use SQLite. On codeplex there are connectors from Win8 Metro app to SQLite DB so check this topic. I also saw somewhere on MS page that SQLite is support in some way. Check it
What Fixus said is correct. Personally , since my app doesnt have a large amount of data to store locally (it goes against the Metro guidelines to store large amounts of data) I serialize the objects instead to local storage. When needed, and if internet is available, the services will be called and the local data updated.
If you choose to use SQLlite make sure you use the real deal and not a third party db, as the DB library must be approved by Microsoft if you want to get the app accepted to the windows store. I'm not even sure that SQLite is yet approved, but by the looks of it they will be.
Tim Heuer always writes great articles on the subject, this one might help you
Let me know if you need help with serializing in WinRT, if you need it.
Best of luck!
We recommend using SQLite database with LinqConnect - Devart's LINQ to SQL compatible solution which supports SQLite engine (provided by http://code.google.com/p/csharp-sqlite/). You can employ LINQ and ADO.NET interfaces with our product. Starting from the 4.0 version, LinqConnect supports Windows Metro applications: http://blogs.devart.com/dotconnect/linqconnect-for-metro-quick-start-guide.html.
If you're building some application that has to keep working without any network connection, and needs to synchronize at some point in time, it is necessary to keep a local database.
You can read the following article, which has some basic guidelines and samples.

Supposedly ReportsAnywhere will talk with MongoDB to generate reports. I am not sure if it is using the JDBC driver or a different method. Hoping someone can help me on how to set up reports anywhere database driver/connection to mongodb?
So the ReportsAnywhere author makes mention of building such a product here. Based on his description, this is no using a JDBC driver but pulling data via the native driver.
It looks like he did a presentation at MongoBerlin in October 2010, unfortunately, I cannot any videos / slides from the presentation. The website is also completely devoid of examples.
Given that ReportsAnywhere is a paid-for product and this is an advertised feature, your best bet may be to go directly to ReportsAnywhere. Maybe you'll get lucky on SO, but I would definitely contact their team directly. Looks like Hans, the creator, is also available on twitter.
All,
I'm beginning to explore what frameworks (open source) and tools for building web applications. What should I select and learn for the following layers,
Layer 1
Client side JavaScript / AJAX library or framework that will invoke REST style services provided by layer-
2
Layer 2
Provides a framework to rapidly create REST style services out of existing applications and out of a NoSQL document oriented database provided by layer-3. I need this layer in cases where I need to expose REST style services out of my traditional apps and RDBMS.
Layer 3
Which NoSQL to use - CouchDB or MongoDB that would work well with layer-2?
Will I need a MVC framework like RoR or a web/component framework like Wicket? Am I missing anything?
I also need recommendations for which tooling/IDE (and associated plugins) for the development environment. Thanks in advance for your answers/thoughts.
We've had pretty decent luck using a Java stack:
For the presentation, we use jQuery and jQueryUI, with Freemarker for XHTML/CSS templating, including to invoke REST web services through various UIs.
Restlet (www.restlet.org) is a wonderfully rich framework for crafting REST web services in Java. We decided to use it on a major product after it was strongly recommended to us by the engineering director of a top 10 e-commerce site in the US. And everything he said about it was true.
Unless you know you're going to face a really large amount of write volume, you're probably best off using one of the tried and true SQL databases supporting ACID transactional guarantees. We used Oracle, then switched to PostgreSQL, using the MyBatis (formerly iBatis) SQL Mapper to shield our code from the details of the database. With the advent of 64-bit addresses and scads of inexpensive DRAM, plus SSDs, these old workhorses do scale quite high.
If you are anticipating very large amounts of writes, by all means consider a so-called "NoSQL" database. I heard very good things about Vertica from the top network ops folks at a major technology company last week. MongoDB and CouchDB both look interesting. Or you may be able to leverage persistent distributed cache technology like Redis or EhCache to offload a traditional database.
The task you're trying to accomplish determines the technology you use.
If you're interested in the .NET platform, consider:
RavenDB for the data layer.
WCF Data Services for your REST services layer. Here's a guide to WCF Data Services with some great video tutorials.
If you need a web front-end, consider ASP.NET MVC or plain HTML as you see fit. jQuery and AJAX modules are well suited in both.
Arguably, ASP.NET MVC IS a REST endpoint of sorts, so you could skip the WCF services.
All the above can be leveraged with free tools, including:
Visual Studio Express
Raven DB's HTML interface at http://localhost:8080/
I want a real and honest opinion what do you think of Google Visualization API?
Is it reliable to use becasue when i was reading the documentation i noticed that there are alot of issues and defects to overcome and can i use it to retrieve data from mysql database.
Thank you.
I am currently evaluating it. As compared to other javascript data visualization frameworks, i think it has a lot going for it:
dynamic loading is built-in
diverse, many things to choose from.
looks really great!
framework mostly takes care of picking whatever implementation fits the current browser
service based, you don't need to download anything in advance
unified data source: just create one data table, and have multiple visalizations draw from that data.
As a disadvantage, I'd like to mention security. I mean, because it's all service based, it is not so transparent what happens when you pass data into these API calls. And as far as I know, the API is free, but not open source, so I can't really check what is going on behind the covers.
I think the Google visualization API really shines if you want to very quickly whip up a visualization gadget for use in a blog or so, and you are not interested in deploying all kinds of plugins and libraries (for eaxmple, with jQuery based frameworks, you need may need to manage multitple javascript libraries that work together to deliver the goods). If on the other hand you are creating an application that you want to sell, you might want to keep more control over what components you are using, and I would probably consider using something like Flot
But like I said, I am only evaluation atm, I am not using this in production.
Works really great for me. Can be customized fairly easily. Haven't seen any scaling issues. No data is exposed so security should not be an issue. - Arunabh Das
One point I want to add here is that, Google Visualization API cannot be downloaded, its not available for offline usage. So application which is going to use it must be always connected to internet, otherwise I think it wont be able to render charts. Due
to this limitation, this API cannot be used in some applications for which internet connection is not available.
I am currently working on a web based application that will have the Google Visualization API added to it and from the perspective of a developer the Google Visualization API is very limited in what you can do with each individual Chart and if I had a choice I would probably look at dojox charting just because of the extra flexibility that the framework gives you.
If you are doing any kind of large web application that will use charting extensively then I would not recommend the Google Visualizations API it does not have enough flexibility for a large web application.
I am using Google Visualization API and I want to stress that they still won't let you download it, which means if their servers are down, your app will be down if you depend on it. I have been using it for about 4 months, and they have crashed once me once so I'd say they pretty reliable and their documentation is really nice.
