13. When should we choose to use Design view over table design using wizard?

Ans.Wizard is useful in creating a table quickly using an existing template. Wizard is useful for the beginners                in using the database application.

Table Design view provides complete control to the user to specify fields, their types and to set various                 properties of each field.


14. What do you mean by referential integrity?

Ans. Referential integrity is the way to ensure that accurate and consistent data is stored in the tables with minimised data redundancy. It is a way to minimise redundant data. It also ensures accurate data storage by checking that foreign key values entered match with the primary key values, by preventing unnecessary deletion or update of data. If user needs, it also ensures that if a primary key value is deleted or updated, the matching records in other related tables also delete or get updated through cascade effect.


15. Why is it important to plan the complete design of the table before creating it in Design View despite the fact that the table can always be modified later?

Ans. We can modify the table structure in Design View any time later also as and when we need but it is a good practice to plan the table designs first. The reason is that after the records are entered in the table and then we realise that a field needs to be modified, removed or added then any change may conflict with the already set properties of the filed or in case of field removal it will lead to data loss. So, to avoid such hassles after data is entered we must either plan the table designs first or at least modify them before any data is entered in the table.


16. What do you mean by sticky keys?

Ans. Sticky keys allow the user to keep the key active when it is pressed once and when any other key is pressed then it is processed by the computer with the currently active key.

For example, if user has pressed Window key on the keyboard then it will remain active. Now, if user    clicks only letter E then it will be interpreted as Windows+E and Windows Explorer will open up.


17. Explain the Buddy system for workplace safety.

Ans. Buddy system is a risk control measure in workplace safety wherein two co-workers are paired as part of safety management practice with the responsibility to ensure mutual safety at work place. Each member of the work group is observed by at least one other employee in the work group. The primary purpose of this system is to provide instant aid to employees in any emergent situation at workplace.


18. What must a user do to ensure security on internet?

Ans. To ensure the security on internet one must practice the following methods:

i) Use strong passwords, with combination of letters in both cases, numbers, and special characters which makes a password difficult to crack or guessed by others.

ii) Regularly backup your data on an offline storage like external drive, disc or tape drive etc.
