paper-based data acquisition systems have many disadvantages, however there are one or two advantages. Listing the drawbacks before these include:
- need a steady supply of consumable items such as pens, ink, toner, staples, file dividers, file cards, boxes d ' archive and electricity.
- because they are based on good writing skills that are often illegible.
- input fields are often too small for their content, especially if the user writes in great script.
- Pieces of paper can be easily lost, misplaced or mis-presented and once lost the original is irremediable
- Paper documents can be easily damaged especially if they are maintained within wet factory environments
- paper documents need physical storage space, files and archives that can store documents in the dry and parasites soundproofed.
- People can inadvertently forget to complete the trace-ability information, such as dates, times, and signature fields.
- People can accidentally enter the wrong data in the wrong fields.
- The paper generally should be carefully monitored, collected and stored
- Because of space limitations, paper forms may need to be in more than one form, doubling or even tripling the consumption consumables.
- calculated items can be requested or data may need to be checked against the upper and lower tolerances. Doing this manually can easily lead to errors.
- If a paper document to be sent to an interested party has requested would have to be scanned in a PDF format before sending.
- errors can easily occur where the products are to be classified manually against more specific ie A grade, B grade, C grade etc.
- Errors can easily occur where handwritten forms They are based on the writer detect, highlight and react to specific results.
- direct statistical analysis of the acquired data on the card is almost impossible without anyone touching the data into a spreadsheet or database, or use services or expensive optical character recognition (OCR) software to convert first.
Advantages of the card data acquisition systems include:
- a computer terminal is not required to be present at the point of use.
- card data acquisition systems can not crash like a computer can
- Very little training is required to use a paper form
Disadvantages of a computer based data acquisition system comprises:
- a computer terminal is required at the point of use.
- Computers can crash and lose data
- Some initial training may be required in using the system
The advantages of a system of computer based data acquisition include:
- that computer equipment uses low levels of consumption, because there is no need to print the finished reports. data
- typed is always readable.
- The input fields for the data provided online can wrap car to allow extra room for bigger pieces of data while maintaining readability.
- robust automated backup systems that duplicate data on two different media can make documents stored for very secure computer.
- If an electronic data file is accidentally moved (drag and drop) can be easily found using the computer search technology standards.
- electronic documents not distributed are generally printed in an office environment. If they become damaged it is easy to simply reprint another.
- Computing takes relatively little physical space.
- electronic systems can include robust systems of access to capture the signatures of responsibility and other access specific details
- Simple data validation to make input errors unlikely.
- electronic systems can be made to read the bar codes on the users' identity cards. based systems
- computer can easily lock date and time fields automatically ensuring important trace-ability data is lost.
- the data acquired does not need to be delivered in person how the system should automatically save data. Computer captured data can also be self archived after a specified period given user.
- Because captured computer data is of a uniform character size, more data can fit on an A4 printed form, while maintaining readability.
- computer can automatically check the items against the tolerance allowed and auto calculate the error fields.
- electronic documents can be e-mailed to interested parties without having to be copied or scanned before.
- The computers can grade products car into more easily complex specifications.
- The computer can easily highlight specific results making sure no one accidentally missed.
- electronically captured data can be easily locked to prevent further editing or deletion.
- electronically entered the data can be validated and locked if the wrong type of data was automatically entered.
- data collected in electronic format can be easily collected and analyzed, without the need for further processing.
In all there are many more advantages to use the acquisition of computerized data than paper-based systems. However, many people still not 100% of the trusted computer. We have all lost data from time to time, but this is usually with software that allows the user to turn off automatic backup functions. A well-designed system should be easy to use and secure data.
