Content Management nalization and standardization ofcontent, and so on. A CMS is asoftware application that facilitatesthese tasks without the need forknowledge of HTML, CSS, or anyother web programming language.The two factors must be consideredbefore an organization decides toinvest in a CMS. First, anorganization's size and geographicdispersion must be consideredespecially if an organization is spreadout over several countries. For theseorganizations, the transition to CMS ismore difficult. Secondly, the diversityof the electronic data forms usedwithin an organization must beconsidered. If an organization usestext documents, graphics, video,audio, and diagrams to conveyinformation, the content will be moredifficult to manage. The features of aCMS system vary, but most includeWeb-basedpublishing,formatmanagement, revision control, andindexing, search, and retrieval.Information on the web is growingtremendously, and searching on theInternet today can be compared todragging a net across the surface ofthe ocean. Content is in essence, anytype or ‘unit’ of digital information. Itcan be text, images, graphics, video,sound, documents, records etc. or inother words anything that is likely tobe managed in an electronic format.The Internet’s explosion created anew set of problems for siteadministrators.Producingandmanaging content was becomingincreasingly difficult. A system wasneeded to manage, create, anddistribute various forms of content.TheContentManagementiseffectively the management of thecontent, by combining rules, processand/ or workflows in such a way thatits electronic storage is deemed to be‘managed’ rather than ‘unmanaged’.The new domain in its own right, as ithas employed the technologies andstrategiesofdigitalcontentmanagement to address businessprocess issues, such as records andContent ManagementtechnologiesincludeContentManagement Systems (CMS), Blogs,Wikis, and RSS etc. There are manyContent Management Software’sused like Joomla, Drupal, Bitweaver,Mambo, Pligg, Plone, Post Nuke,Tweak, zope etc.Application that enables users tomanage content in an orderly fashion,Content can include a variety of filetypes such as text, images, andmedia, which a CMS helps to create,edit, store and publish. The seen thatis more flexible and easier than thetraditionaltools.Thenew2

Content Management System (CMS)both can maintain the site to theirdesired control, even though bothhave different levels of technicalknowledge. After the arrival of Web2.0 technologies, many tools arethere in the seen, which are moreflexible and easier than the traditionaltools. It is capable to create apowerful portal website in a matter ofminutes and it has wide supportingcommunity. CMS consists of acontent management applicationwhich enables the management andmodification of content withoutadvanced webmaster knowledge, anda content delivery application, thatuses new information to update thewebsite. The CMA element allows thecontent manager or author, who maynot know HTML, to manage thecreation, modification, and removal ofcontent from a Web site withoutneedingtheexpertiseofaWebmaster. The CDA element usesand compiles that information toupdate the Web site.CMS means a tool for managingcontent, usually on a web site, thatseparates the design, interactivity,and content from one another tomake it easier for content authors toprovide content. CMS is a computerapplication used to create, edit,manage, search and publish variouskinds of digital media and electronictext. In simple terms, contentmanagement can be defined as aprocess of creating, collecting,organizing,categorizingandstructuring information resources ofany type or format so that they can besaved, retrieved, published, updatedand re-purposed in any waydesirable. A CMS is responsible forthe collection, management, andpublishing of chunks of informationknown as content components. Thebenefit of using a CMS, especially forwebsite creation, is that it does notrequire an extensive knowledge ofcoding. The CMS provides a bridgebetween the seasoned coder and theweekend blogger; in the sense that,CMS Subsystems:A CMS is composed of various subsystems that interact with these:i. Collection:Subsystem which handlesthecreationand/oracquisitionofinformation. It must provide supportfor the processes of content creation,workflows, syndication and integrationof external sources. In addition, itmust provide support to conversionprocesses between different formatsas well as for the incorporation ofcontents from different sources withinspecific structures.ii. Management:Subsystem in charge of themanagementandcontrolofinformation repositories, user groups,and support processes for othersubsystems. It handles the definingand controlling of information flows3

used by other subsystems, as well asthe definition of parameters for thefunctioning of the system.iii. Publishing:Subsystem in charge of finalproduction of publications and digitalinformation products in an automaticor semiautomatic manner. It makesuse of a model based on templatesand must provide personalizationoptions for users as well as thepossibility of producing for a variety ofplatforms and/or customers.Types of Content Management System:These terms describe the deploymentpattern for the CMS in terms of whenpresentation templates are applied torender web pages from structuredcontent. There are some major typesofCMS:Enterprisecontentmanagement systems, Web contentmanagement systems, Mobile contentmanagement system, ComponentcontentmanagementsystemDocument management system andLearning management system, etc.i. Enterprise content management systems (ECM):An enterprise content management(ECM) system is concerned withcontent, documents, details, andrecords related to the organizationalprocesses of an enterprise. nformation content, with all itsdiversity of format and location.ii. Web content management systems (WCM):A web content management (WCM)system is a CMS designed to simplifythe publication of web content to websites and mobile devices, inparticular, allowing content creators tosubmit content without requiringtechnical knowledge of HTML or theuploading of files.iii. Mobile content management system (MCMS):capable of multi-channel contentdelivery. Mobile content delivery hasunique, specific constraints includingwidely variable device capacities,small screen size, limited wirelessbandwidth, small storage capacity,and comparatively weak deviceprocessors.It is a type of (CMS) capable ofstoring and delivering content andservices to mobile devices, such asmobile phones, smart phones. Mobilecontent management systems maybe discrete systems, or may exist asfeatures, modules or add-ons oflarger content management systems4

iv. Component content management system (CCMS):It is a (CMS) that manages content ata granular level (component) ratherthan at the document level. Eachcomponent represents a single topic,concept or asset (e.g., image, table,product description). Componentscan be as large as a chapter or assmall as a definition or even a word.Components in multiple contentassemblies (content types) can beviewed as components or astraditionaldocuments.Eachcomponent is only stored one time inthe content management system,providing a single, trusted source ofcontent.Componentcontentmanagement (CCM) is typically usedfor multi-channel customer-facingcontent (marketing, usage, learning,support).v. Learning management system (LMS):Some LMSs are Web-based tofacilitate access to learning contentand administration. LMSs are used byregulated industries (e.g. financialservicesandbiopharma)forcompliance training. It is also used byeducational institutions to enhanceand support classroom teaching andoffering courses to a larger populationof learners across the globe.It is a software application for theadministration,documentation,tracking, and reporting of trainingprograms, classroom and onlineevents, e-learning programs, andtraining content. LMSs range fromsystems for managing training andeducational records, to software fordistributing courses over the Internetwith features for online collaboration.vi. Document management system (DMS):document imaging workflow systemsand record management systems.Severalwebbasedcontentmanagement systems exist both inthe Open Source and commercialdomains. However, this is one areawhere (OSS) has gained dominanceover proprietary counterparts.It is a computer system (or set ofcomputer programs) used to trackand store electronic documentsand/or images of paper documents.The term has some overlap with theconcepts of (CMS). It is often viewedas a component of enterprise contentmanagement (ECM) systems andrelated to digital asset management,5

Work chart of CMS:Content Management System (CMS)allows designers to focus on designby building templates. Subjectexperts build content in a separateenvironment. The server takes thecontent, inserts it into the correcttemplate and sends it all, neatlywrapped up, to end users. But that’sjust the technology side of CMsystems. CM’s other aspect is theway it addresses your workflow.Sure, it’s great to separate thedesign from the content, but CMwants to streamline how yourdesigns get approved and onto theserver.Create a design in whatevertool/environment you’re comfortablewith. Once it’s tested and ready to go,you pass it to your manager or editoror boss or whoever okays yourdesign. If it’s approved, it’s sent on tothe server. If not, you get notes and itis sent back to you, all within the CMenvironment: no email, no voice mail,no printouts of your design with redink and yellow sticky notes all over it.The same process happens on thecontent side. The end result is thateven though it’s easier for contentand design to publish, there are stillstrict controls as to what makes it tothe live server.Content Management Tools:facilitate reuse and enable flexiblepresentation options. Administrationis typically done through browserbased interfaces, but some systemsrequire the use of a fat client. UnlikeMost systems use a database to storecontent, metadata, and artifacts thatmight be needed by the system.Content is frequently, but notuniversally, stored as XML, to6

Web-site builders like MicrosoftFrontPage or Adobe Dream weaver,a WCMS allows non technical usersto make changes to an existingwebsite with little or no training. AWCMStypicallyrequiresanexperienced coder to set up and addfeatures, but is primarily a Web-sitemaintenance tool for non-technicaladministrators. Content managementtools allow anyone to edit their ownwebsite. Do not need to know HTMLor any other web language. ThisContent management, tools are away for a privileged user to makeupdates or additions to a web pagewithout the need for extensivetechnical knowledge. This allows acompany to easily modify its site atany time through a simple webinterface. Content management toolsallow companies to take control oftheir Web pages by managing thecontent as distinct from the design.The days of writing HTML for largeWeb sites may be numbered ascontent management tools take thefloor. Many organizations build thecontent management tools to meetthe specific needs, but in the last fewyears, several organizations havecome out with some good contentmanagementsoftware,someexamples of these are given here.http://www.daisycms.org:Daisy is a Java/XML open-sourcebased on the Apache Cocoon contentmanagement framework.

Conclusionwill be responsible to present libraryto the global community throughWWW. But gradually, it becamedifficult to maintain and update thewebsites because of their verydynamic nature and a variety of fileformats.ContentManagementSystems (CMS) evolved as analternative to such web-authoringtools. These procedures can bemanual or computer-based. It enableseven non-technical users to efficientlybuild a website, streamline the webpublishing procedures and quicklydeploy them, creating a content- richwebsite.Informationanddocumentationservices available on the Internetthrough web servers are growing inan exponential manner. In recenttimes,thefieldofcontentmanagement system has seenparticularly strong growth in opensource solutions, perhaps in directresponse to the very high prices thatcommercial content managementsystem have historically demanded. .This activity will give the staff anindication of what works and whatdoes not, what is interesting to theonline visitor and what is not pleasantto use.
