Why must you use a primary key?

A primary key uniquely identifies a row in a table. A table without a key is not in normal form (i.e. considered a bad practice). Without a primary key, a database programmer risks inadvertently updating or deleting more records than they intended.All tables should have a primary key, although this key may be a composite of various fields.For example, if a developer uses "update contacts set firstname = 'John' where firstname='Jacob' and lastname = 'Smith'", they will likely update many records when they may have only intended to update a single record. By using a unique key, a developer can instead state "update contacts set firstname = 'John' where uid = 1234", and only a single record will be updated.Primary keys also increase access to specific records when the developer knows ahead of time what specific value they are looking for. For example, a developer might display a list of contacts matching a first name and last name, and when the user selects a specific record to view, retrieving by the primary key will be faster than querying by multiple indices (such as first name and last name).

What are merits and demerits of magnetic tape?

Merits: Magnetic tape is an inexpensive and reliable data storage option for large amounts of data. It has a long lifespan and can be easily stored offline for backup purposes. Demerits: Magnetic tape has slower read/write speeds compared to other storage mediums like solid-state drives. It is also susceptible to damage from magnetic fields and requires specialized hardware for reading and writing data.

What is meant by democracy and explain the merits and demerits?

Democracy is a system where all the citizens get a vote, and things are decided that way. "Citizens" may be a distinct category from "the population", such as in slave societies, or societies where the vote is restricted to certain classes. The merits are that it keeps the many from being ruled by the few. The demerits are that the few are then ruled by the many. It has been truly said that a lynch mob is democracy in it's purest state. 99 men are voting for the hanging, one man is voting against the hanging. The "ayes" have it.

What is impedance voltage in a transformer?

Power transformers have an impedance (Z) rating that is listed in %. So the nameplate might state 5% Z for example. What this means is that when the secondary conductors are bolted together then 5% of the rated primary voltage is applied and will generate 100% current in flow in the secondary. Example: you have a 75KVA Delta-Wye 5% Z transformer with a 480V primary rating and 208/12 secondary rating. The amp rating of the secondary is 208A [75,000/(1.732x208)] So if you applied 24VAC to the primary with the secondary bolted together with busbar then you would have 208A of current flow.
