      Adobe Dreamweaver is a web design and development application that provides a visual WYSIWYG editor (colloquially referred to as WHAT YOU SEE IS WHAT YOU GET) and a standard code editor with features such as syntax highlighting, code completion, and code collapsing as well as more sophisticated features such as real-time syntax checking and code introspection for generating code hints so as to assist the user in writing any code.Adobe Dreamweaver is available for both OS X and Windows.

     The Design view allows rapid layout design and code generation as it allows users to quickly create and manipulate the layout elements of HTML.Dreamweaver features an integrated browser for previewing developed webpages in the its's own preview pane in addition to allowing content to be opened web browsers installed locally.

     Dreamweaver can also use third-party "Extensions" to extend core functionality of the application, which any web developer can code (mostly in HTML and JavaScript). Dreamweaver is supported by a large community of developers who make various extensions available (both commercial and free) for most web development tasks from simple rollover effects to full-featured shopping carts.

     Dreamweaver, like any other HTML editors, edits all of the files locally then uploads them to the remote web server using FTP, SFTP, or WebDAV protocols. Dreamweaver CS4 now also supports the Subversion (SVN) control system.

BIG DATA

BIG DATA

     The term "Big Data" was coined by Haseeb Budhani,  "Big Data" caught on quickly as a blanket term for any collection of data sets so large in terms of size and complex that they become difficult to process using available database management tools or data processing applications.

     The challenges of big data include capture, curation, storage, search, sharing, transfer, analysis and visualization of the data.

     Big Data usually has data sets of sizes beyond the ability of commonly used software tools to capture, curate, manage, and process the data within a acceptable time.Big data sizes are a constantly moving up, as of 2013, a single data set  ranging from a few dozen terabytes to many petabytes of data.

     The challenges for big data include capture, curation, storage, search, sharing, transfer, analysis and visualization. The trend to larger data sets is due to the additional information that can be derivable from analysis of a single large set of related data, as compared to separate sets that are smaller with the same total amount of data, allowing correlations to be found to "spot business trends, determine quality of research, prevent diseases, link legal citations, combat crime, and determine real-time roadway traffic conditions.

     Today's data comes from multiple sources. And it is still an difficult to link, match, cleanse and transform data across systems. However, it is necessary to connect and correlate relationships, hierarchies and multiple data linkages or your data can quickly spiral out of control.

BETA TESTING

BETA TESTING

     Beta testing can be considered to be a form of external user acceptance testing.The software is released to a group of people so that further testing can be done to ensure that the product has no faults or bugs.Beta versions are also sometimes made available to the public to facilitate in the increase of the feedback maximum number of future users.

     Generally a release notes file is included with each beta version. Release notes reveal certain information about the product like:

•  version number of the product,
•  technical requirements for the machine that is to be used for testing,
• the list of changes from the previous version, and,
• descriptions of known problems about the product.

     A beta version is NOT the final version of the product and hence the developer of the product does not ensure an absence of errors that could disrupt the computer's operation which could result in data loss.

     Consequently, beta testers use the beta version at their own risk and the manufacturing company has no responsibility for any consequences that may arise out of the use of the beta version.
