If a database is not maintained or if incorrect data is entered into the database, serious problems can occur. What problems cou
Archy [21]

Database is maintained by keeping only relevant data and updating existing data in a timely manner.

This is achieved by issuing proper insert, update and delete operations.

Incorrect data leads to incomplete information. Databases which hold transaction details, any inaccuracies lead to misinformation to its users.

Both the above lead to serious issues in data maintenance and prove the database ineffective. This indicates manhandling of the database.

No maintenance

Database is maintained when only relevant information is present. Irrelevant information includes information like information of past students, old information of current students, etc.

For students who have completed their courses and left, the database should be updated by removing data of such students.

Also, for newly enrolled students, their enrolment should reflect in the official records.

In case of changes in any of the student information, timely update operations should be performed to keep only current data in the database.

All these operations should be done timely in order to avoid any discrepancies in the real data and updated data in the system.

Incorrect data

In situations where incorrect data is input in the student database, incorrect data will be recorded for that particular student. Incorrect data can be related to ssn, name, address, course details and fees payment.

In case of incorrect transaction details like fees payment, this incorrect data will reflect in the student record as well as will affect the overall earnings of the school.

For enrolled students, correct enrollment details regarding the course and classroom should be recorded. Any error in this data will cause the student inconvenience and the respective student will be at loss.

Also, taking advantage of this situation, any outsider acting as an enrolled student, can gain access to the school.

This leads to mismatch of information and can lead to fraud situations against the educational institute.

Ways by which you can improve your typing speed
grandymaker [24]

1. Keep the size of the keys in mind. The larger they are, the easier it will be to type. That means you may want to look for a keyboard where the keys that you use most often, such as the letters and numbers, are larger than other keys.

2. A keyboard with concave keys that fit the shape of your fingers is a good option if you're looking to eliminate errors in your typing as you try to increase your speed.

3. It's best to choose a keyboard with keys that have strong tactile feedback, which means they offer enough resistance to alert you that the stroke has registered. The resistance also keeps you from accidentally hitting keys as you're typing, so you can type more quickly.

4. When you arrange your fingers on the keyboard, curve them slightly, but keep your hands relaxed.

Make sure that your keyboard is centered directly in front of your body.

5. certain fingers are designated to strike certain keys for the most efficient typing. In most cases, you’ll use the same fingers from the home row to hit the keys that line up in the rows above and below.

Strike the “1,” “2,” “Q,” and “Z” keys, in addition to the “A” key, with your left pinky.

Strike the “3,” “W”, and “X” keys, in addition to the “S” key, with your left ring finger.

Strike the “4,” “E”, and “C” keys, in addition to the “D” key, with your left middle finger.

Strike the “5,” “6,” “R,” “T,” “G,” “V,” and “B” keys, in addition to the “F” key, with your left index finger.

Strike the “7,” “Y,” “U,” “H,” “N,” and “M” keys, in addition to the “J” key, with your right index finger.

Strike the “8,” “I,” and “,” keys, in addition to the “K” with your right middle finger.

Strike the “9,” “O,” and “.” keys, in addition to the “L” key, with your right ring finger.

Strike the “0,” “-,” “=,” “P,” “[,” “],” “‘,” and “/” keys, in addition to the “;” key, with your right pinky.

Hit the “Shift” key with the pinky on the opposite hand from the finger that you’re using to strike the other key.

Hit the spacebar with whichever thumb feels most comfortable to you.

Practice regularly.

These are some effective ways to improve typing speed.
