A paper-based system can only be organized in a single way, cannotbe easily searched, cannot be easily modified, cannot be accessedremotely, cannot be conveniently cross-refer…enced, maintained andupdated, protected, and cannot be expanded without considerableeffort. Computerized databases solve nearly all of these problems. Whereas a paper-based system would need extensive labor andreorganization in order to change the sequence and order of data, adigital database could be re-ordered instantly with a single click;thus, data could immediately be re-sorted based on (for example) acustomer's name, address, age, average order size, credit rating,etc. Then, the digital version could be re-sorted by anothercriteria... and then another, all in just a few seconds. A paper system would require extensive time and man-power to searchfor a given piece of information, whereas a digital database couldinstantly find the required data in any field, instantly. Further,a database system could cross-reference data, finding matcheswithin multiple fields, correlate them, perform arithmeticprocesses on them, and retrieve only the data that matches everysingle criteria. For example, it could find a list of everycustomer in a database with an 'A' credit rating who is engaged inheavy construction projects, who has spent more than $40,000 withyour company within the past year, and whose current fleet ofbulldozers is more than 15 years old... perhaps the perfect leadfor your bulldozer sales representatives. To find, analyze andcorrelate this data by hand would take nearly a lifetime. A paper system cannot be easily modified and expanded. Updatingdata requires removing each record's card or file, erasing the olddata (or waiting while white-out dries because a former employeeviolated the 'pencil only' rule), and then carefully entering itagain. For bulk updates and batch changes, every single record mustbe found and updated individually. If the original filing systemwasn't conceived to take new fields into consideration, you'llresort to writing on the backs of cards, or meticulously writing inmargins, or adding pages to filing systems that were designed for asingle page per record. Not so with computer-based databases. Batchupdates take seconds, with a click-and-drag function. Need toexpand data? No problem, just add a field to the entire databasewith a single click. Did the law recently change, prohibitingcertain information from being maintained on clients? Or does thelaw now require new accountability for record keeping? Examplescould include the FOIA (Freedom of Information Act),or the HIPAA (Healthcare Information Privacy andAccountability Act), or any number of ever-changing state andfederal regulations for nearly any industry. With a paper database,you may well be out of business, but with a digital database,you're instantly back in compliance with just a few clicks. A paper system requires massive amounts of space, climate control,fire protection, lighting, etc. These all add overhead to youroperation, whether in the home environment, or a high-levelcorporate record keeping firm. The paper is a risk, in and ofitself, to life and safety due to accidental fire concerns. Paperfiles are subject to damage from temperature, water (floods,hurricanes), fire, theft, accidental loss and mis-ordering (which,depending on the size of the filing system, could be catastrophicand impossible to correct), and are almost impossible to back-upcompletely, requiring that an entire new system be duplicated fromscratch, perhaps by hand. This dilemma is what prompted thenow-obsolete technologies of microfilm and microfiche (essentially condensed photographic slidesof files) -- so that data could be archived to save space andbackup valuable data. On the other hand, a digital database ofnearly any size could reside on a single computer or small network.Perfect digital backups of data can be made instantly to protectagainst any loss. With a small amount of care and diligent andfrequent archiving (perhaps even automatically), there is no reasonthat there should ever be data loss; these convenient backups cansurvive and maintain an office's operations, regardless of anythreat to the original data, up to and including catastrophes andacts of God. Further, data in a computer database could beencrypted during storage, to prevent any theft or unauthorizedcopying of information. Further, whereas an old-fashioned paper file must be visited to beused, for example the card catalogs that are disappearing fromlibraries everywhere, a digital database, if appropriate anddesirable, can be accessed remotely from anywhere, either securelyby authorized users, or publicly by anyone connected to theinternet. Digital databases fuel internet revenue, essentiallyallowing buyers to check a business's current stock of merchandise,then automatically edit the inventory sheets when they make theirpurchase. That sure beats counting items manually, or riskingembarassing cancellations for orders when a surprise glitch in thepaper filing system shows inventory that doesn't exist, or has beensold. A business's paper-based system could even be discontinued, andproprietary-sized paper, forms, or storage could become impossibleto obtain. The advantages of digital databasing systems over apaper system are innumerable.
Technically, the term Web-Based system refers to those applications or services that are resident on a server that is accessible using a Web browser and is therefore acc…essible from anywhere in the world via the Web.
Well both of these things are related to the record keeping of any organization.File based system was the old method for keeping a record of any organization. In this all the …records are saved in general pages registers. And there are many people for handling these records. There were bundles of registers, in which records of many people are stored either, the income tax record. There was not any computer involved in it. But later on, with the advancement of Information Technology, computer has taken the place of many record keepers. Via data base we mean that a computer programmer create a program or DB in which records of thousand and millions of users can be stored in a one computer, and via one click we can access the record of a particular person. There is no need for finding many registers. A database program for record keeping is install on a single computer for an organization and only one operator can deal with this millions of records. Its simple example is telephone directory, in previous times the numbers of many users was stored on files and finding them takes so much time, but via the database advancement only via one click you can access a person number and address in a second.
The role of databases in computer-based information systems is to offer a management platform. The database will have various controls to the information systems.
It can be hacked, deleted, seen by people who shouldn't see it, the PC may crash and the harddrive wipes...you get the idea
Any system that is needed web browser or internet connection could be categorized into web based system like websites, skype, messenger etc. WEB API is also a part of web base…d development.
A web based system is one that can be accessed via a web browser and typically off-site or off of the network that you are currently on. The new generation of web based system…s are known as "cloud based". Cloud based systems or cloud computing is just an efficient way to manage and utilize hard drive space allocating it as needed. It allows companies to scale their computer requirements up or down almost instantly. The new breed of web based systems also includes what is know as software as a service or SaaS. As internet speed and technology improves all software will be moved onto the web or "cloud based". There will no longer be a need to buy and install software locally or worry about different versions or reinstalling the correct version in the event of a catastrophe. Filocity.com has built this platform today. MS Office and PDF documents can be created, edited and shared online with no need to worry about your computer or hard drive failing. You can work locally or online and all of your files are safely stored with version controls to insure you are working on the latest document. This will become the standard for all web based systems
i converted over to linux mint 12 a while back from windows, i tried a few others like chrome os, ununtu, and some others. but this os seems to the best. and hardley takes u…p any space.
There are a few different ways that you can connect depending on what database you choose. Most of your major Enterprise DBMSs allow you to connect using an IP address, a …database name, a valid user name and password.
There are many examples of web based systems. Some common examples as of May 2014 include online retail stores, online web email, and online auctions.
A non-web based system might be a stand-alone system or a desktop based system which might also be referred to as an native application for a specific operating system.
A web-based OS is a system where all the applications and data his held on the internet. The operating system is essentially like any other operating system except that it run…s out of a browser.
database is a collection of related data in any size and in any complexity whereas database management system is software for defining, constructing and manipulating databases… for various reasons.
The Relational Database Management System was based on a good model. It is based on first-order predicate logic which was discovered in 1969 by a man named Codd.
The similarities are: Database schema may be similar (Primary keys, foreign keys and indexes etc) SQL (Structures query language is also similar in a way) Referential integrit…y is also similar to a great extend)
One can find a web-based database online on a few different websites. These sites explain in more detail the extent of this database and its function.
In Heuristic-based Optimization, the query execution is refined based on heuristic rules for reordering the individual operations.
