I tried to understand what is the use of this tool but could not understand much from blogs and oracle docs.
My questions are:
What are the highlights/features of this tool which make any company or architect decide that this is the appropriate tool they need for their web application?
How is different from other java IDEs like netbeans and eclipse?
WebCenter is not a tool. It is a branding of 3 different technologies brought together to support user interaction via web sites (WebCenter Sites = Fatwire), portlets, content management (WebCenter Content = Stellent), and WebCenter Portal, rebranded from Spaces (which is similar to MS Sharepoint) is a pre-built web site with support for collaboration and integrates with Sites and Content. We use Jdeveloper to design and build the pages (ADF Faces - JSF) that make up the sites, we use the Sites tool to build the site and WC Content has it's own interface to check in content, edit, manage, search, etc.
Lots here and here as well as: WCContent, Sites, Portals.
You might also want to download the free Virtual Box image here, and play with the software. There are myriad books and tutorials that can be found with a little searching. Also, consider taking a class with Oracle which will explain these technologies in detail.
Also, my aggregation site here, lists many books, blogs and tips that may help.

I have a question about Solr. It is described as an enterprise search platform. Are there Enterprise oriented search platforms and general purpose search platforms? Can't you just use Solr for example to build a general purpose search engine? If there is such a distinction what are the major differences between them?
Enterprise is a vague term tacked on to things to say "Yes, you can totally use this in professional projects, it's super good". It's baloney, in short. When reading the front page of a software product (or any product really), I find it useful to ignore all adjectives and adverbs, which makes that first sentence on the Solr page read: "Solr is the search platform from the Apache Lucene project."
Don't know why I don't get hired to write ad copy.
I think it would be fair to say that Solr is a general purpose search server, sure (depending on what general purpose entails to you, of course). It indexes data, allows you to search it, and provides a lot of tools to do that in the way the best suits your data and users.
The term Search is overloaded with lots of semantics. It is often used to denote/describe either an action, a function or a technology. But more important wit respect to the question is the fact that there are two common kind of "search projects" which are Web Search and Enterprise Search projects.
Web Search is typically about indexing content from one kind of content source (Web Servers) serving content in html format. Most often it's only about public content and document level security is not an issue. A typical example for this kind of solution is Google's Web Search, but most full-text Site Search solutions can also be seen as good examples of this category. For a basic solution a crawler , an html markup removal tool and an indexing library and some "glue" is sufficient. Apache Nutch or Apache Solr and ElasticSearch in combination with a web crawler are good candidates to be used for implementing these kind of solutions.
Enterprise Search is typically about integrating content in various formats from multiple content sources. A typical example for this kind of solution are corporate intranets, but Search Based Applications often also fall into this category. Those solutions typically come with additional requirements such as support for document level security, advanced linguistics, metadata extraction, data mappings and enrichments, synonyms etc. The projects are more complex and a more complex technology stack is needed. While Apache Solr or ElasticSearch can both be used, a lot of the required functionality is not part of the standard download and needs to be developed or integrated as part of the project. But for both - Apache Solr and ElasticSearch - there are also commercial distributions available that already expand the functionality of the standard download into the direction of Enterprise Search. Other good alternatives are commercial search engines.
I agree with #femtoRgon that Solr:
is a good General Purpose Search Platform
and not an Enterprise Search Platform
but an Enterprise Search Platform can be built with Solr
Solr is a search platform that can be customized for either general purpose search or for Enterprise Search solutions. As suggested by Daniel in the previous comments, ESearch application is used specifically for an enterprise/organization to search for the organizations internal data and also in some cases can search external content as well but only related to the organization. Enterprises generally use various systems which are either internally developed or by a vendor and the ESearch application should be able to connect to the internal systems and index the content including the different file types, metadata and importantly security that is associated with each and every document from those systems.
To conclude, Solr is a Search system which can be used to index and search content as a general or as a ESearch application for a organization.
I posed this question to my lecturer, but I would also like a variety of answers in order to better understand this conundrum of mine. Here is the original message with names omitted.
Hi **,
Thank you for your intro lecture today, I look forward to the work involved in the coming weeks.
I am however, rather confused regarding the terms CMS, API and Framework. The internet isn't providing much help either because these terms get thrown a lot and often for the very same thing!
A have a bit of background in LAMP web development, and I will provide a hypothetical scenario, where hopefully you can tell me where these terms would fit in.
I am using LAMP (Linux web server with Apache, MySQL and PHP).
I am developing a website whereby the public can watch movies (umm... ignore the legal issues, purely hypothetical and for educational purposes of course!)
I create my MySQL database using phpMyAdmin, and tables will involve 'users', 'categories', 'content' etc.
I now create an 'admin control panel (CP)' which I will refer to as the back-end. Authorised users, depending on their access levels (as determined by their account in the 'users' table) can add/edit/delete various things. These changes are reflected on what I call the front-end.
The front-end is the public facing website, whereby the public visit this website to watch films of their choice.
The back-end (i.e. the Admin CP) controls/regulates the content of users and pretty much everything. Over time, the developers could add more features to this for more functionality. E.g. a comments. Alternatively, a developer could use the Facebook comments API to include into every 'film' page on the front-end, this makes it a lot easier.
Now back to the main question at hand, is this a web CMS? Where would an API fit into this? Is this a framework?
Note: I'm not using anything like WordPress or Joomla etc., it's all custom coded by myself. Using PHP and HTML5, CSS3, maybe a bit of jQuery too, and of course SQL statements via PHP to interact with the MySQL database.
I appreciate your help in this confusion of mine.
Thanks,
EDIT: I have commented my thoughts based on Justin's input. If I'm on the right track let me know, cheers.
Thanks for the post.
The three terms you have stated are used quite often around the web, and they are always changing. First you have a CMS, CMS stands for Content Management System, like above you have stated Wordpress and Joomla. That is where someone has already created the software to create a site/blog without having to mess with PHP, MySQL, and Apache. You are merely doing anything on the front-end, just simply posting your content, and making it live. The software does all of the back-end work for you.
API, simply put. Open-source "plug-in" which allows the user to integrate a service or application into their site or application for use.
Framework, Like Bootstrap, created by Twitter. A Web Framework is an easy way to develop a site on the front-end. It gives the learning amateur a chance at developing the front-end while learning great concepts along the way.
I need to share info using different services like twitter, facebook, and many more, then found the AddThis Documentation and want to know the key advantages of the problems of using them SDK.
Do you recommend me to use a different library?
I've heard a lot of praise for ShareKit. While I haven't used it myself, it seems simple enough to set up (only 3 lines of code, according to their site) and multiple services are supported.
I'm not a developer by profession. Therefore, I'm not exposed to real world technical problems that face professional developers. I read/heard about web farms, integration between different systems, load balancing ... etc.
Therefore, I was wondering if there are ways for the individual developer to create an environment that simulates real world situations with minimal number of machines like:
web farms & caching
simulating many users accessing your website (Pressure tests?)
Performance
load balancing
anything you think I should consider.
By the way, I have a server machine and 1 PC. and I don't mind investing in tools and software.
PS. I'm using Microsoft technologies for development but I hope this is not a limiting factor.
Thanks
Since I am new, SO will not let me post more than one link, so I compiled a list of links for you at a pastebin here.
alot of tools for this. i like
http://www.acme.com/software/http_load/
and http://curl-loader.sourceforge.net/
they both can simulaty much queries to your server. Run it from another machine.
I'm very impressed with my initial tests with db4o. However, i'm wondering just how many enterprise class websites are out there powered by db4o, i couldn't see any on the main website?
I can't see any reason why db4o should not be used. There appears to be decent enough support for transactions and ways to handle concurrency for example.
Anyone got a list of websites i could look at?
See:
http://developer.db4o.com/Projects/html/projectspaces/gaabormarkt.html
A particular search engine used to be powered by db4o (I say "used to" because I haven't talked to the author about this since a long time).

The author is Travis Reeder.
Although I cannot see websites specifically, here is a list of Open Source Projects from the db4o website:
