Computers will produce inaccurate outcomes only if the info inputted is incorrect. If an input is scanned in by a laptop this reduces the risk of mistakes. In my system it is important that all the data can be accurate and correct. You will find two key ways of attaining this. These are generally Verification and Validation. Confirmation allows me to make certain that the data entered into my method is correct. This is very important since each time a new patient comes to sign up for I will need to collect the best information.

As for validation, this will likely be valuable so you can set various bank checks and limit the faults in the info.


By simply verifying what the computer confronts you can reduce errors, like if you are in a catalogue shop and you notify the person behind the until a number and it comes up with a product. This item is then examined with the customer to check that it can be the right item.

The product is then sent down from other storage floors and is once again verified that it can be indeed the right item. This kind of constant confirmation greatly minimizes errors

Let me need to employ verification in two cases. These are arranging an appointment in either person or upon phone and when a new affected person joins. I will deal with both of these situations independently, firstly with booking sessions.

In reserving an appointment both on the phone or perhaps in person I will need to gather the following info.

* Patient Number

5. Patient Term and Surname

* Deb. O. B

* Time and date of scheduled appointment

I asking for the patient’s number can verify these. When I possess collected this I would need to ask many questions, including the patients addresses or M. O. B to verify that this is a right person and no one is trying to help to make a hoax. Once I have got all his or perhaps hers specifics and allotted them a GP, Let me check the info over again to confirm that their all accurate. This will all be inserted directly into the system.

If a patient cell phone calls over the telephone I will utilize same technique of asking their Patient Amount than requesting a question including their D. O. B to see if it’s the right person. Again once I have adequate facts to confirm that isn’t a scam I will set aside them a GP, and check the data over again to confirm that it is right. In this case the information would end up being input straight into the system.

If a new individual comes based on how busy the surgery will depend what data access method I would personally use. If this were busy then I could issue anyone a paper-based copy with the Patients kind for them to fill in. Once they got finished this I would keep these things check over it to confirm that all the information is proper. If the surgery wasn’t busy then I will instead inquire further the question inside the intend that they can answer the questions for me to put the answers directly in the online system. When all the questions was asked I might then go over the answers once more to confirm everything is proper.

This is how verification will be used within my system.


Validation is a process of discovering any data that is erroneous, incomplete or perhaps unreasonable. Your computer programme executes validation.

Acceptance programmes can perform a few or all the following bank checks

Character type checks

Character checks to make certain that the right kind of characters had been entered just like characters high should be character types and figures where there needs to be numbers

Selection checks

Which a value entered is in the correct range at the. g. 18 is not only a valid grow older for a pension check

Hash Counts

This will make sure that the ideals on something such as an bill have been keyed in properly the hash total does not have any real meaning as a number

Control total

A control total is much like a hash total except the total includes a meaning such as the cost of a thing

Check numbers

When a quantity is straight inputted to a computer you will have errors and check numbers are a way around this we call up barcodes Worldwide Standard Book Number or perhaps ISBN

Transliteration checkers

Virtually any software with words in it should include a spell checking function

Length checks

Sometimes a specific item info should always be a particular number of personas, then the size checker can alert you that the principles are incorrect

Types of Errors

You will discover two primary types of errors they are:

Transcription problems

Misreading or misunderstanding data causes these types of, this could be caused by bad handwriting or confusing handwriting such as where the page s appears like the number your five.

Transposition mistakes

These problems occur wherever two digits or words are inter-changeable around as if you are working at high speed an individual always consider the screen so it will be common to type ot rather than to or perhaps 5124 instead of 5214 about 70% of all errors happen to be transposition problems.

Within my system I have used Validation to hopefully boost it and limit mistakes.

1 . Below you can see which i have employed validation to limit the quantity of characters that may be inputted in to the surname.

installment payments on your Here Personally i have tried a data type filter therefore no quantities can be inserted in to the person’s surname. This does not stop errors but will limit the blunders within my system.

three or more. Here Personally i have tried an type mask this is so you immediately put a capital at first of a label. This rectifies the mistake of forgetting that will put a capital at the start of any surname.

An additional, and more exact method of acceptance within my own system is the usage of an suggestions mask. We used a basic type of suggestions mask in 3 previously mentioned and here is another part through which I have used an input mask.

Here you can see another example of an suggestions mask inside my system. That one is used intended for the Postcode. As you can see this kind of input face mask reduces blunders by allowing the 1st two numbers of the Postcode to be capital letters just and the next two quantities only. Then it has an computerized space. The next figure is known as a number with the remaining two being capital letters. This input cover up is a good technique of validation as it doesn’t enable you to insert letters where quantities are required and vice-versa. In addition, it automatically constitutes a space as part of your Postcode.

The final method of Validation used in my own system is the combo field. With this kind of it simply allows for a set volume of answers. Naturally this can only be used on a field that only offers set answers such as “sex or “title. I have actually used this on both of the prior stated.

1 . Firstly I have collection the type of control to Combination box.

2 . In row source I use then picked the ideals that you can select from. As you can see the only values selectable for the “title desk is Mister, Mrs, Miss, Ms and Doctor. This has set up my own combo box for use in both my patient’s type and table as you can see listed below.

The above cases both demonstrate combo container working effectively in my databases. This truly limits the mistakes manufactured since it is usually impossible to but Mister as MMR and Doctor as SDFS. It permits is period saving besides making sure that your data isn’t uncommon and incomplete.

As you can see the verification and validation strategies used in my personal system enable me to have more accurate info, which is essential within a databases of this importance. As the purpose of this component to my program was, it allows me to ensure that the data suggestions into my personal system is appropriate.
