A blood bank maintains two tables - DONOR, with information about people who are willing to donate blood and ACCEPTOR, with info

Kipish [7]

Answer:

The sql query is given below.

Since we need to count of males and females for a particular blood group, we put xxx for the blood group.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors,

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Explanation:

The clauses in the query are as follows.

1. SELECT: all the columns required in the output are put in this clause.

2. FROM JOIN ON: the table(s) from which the above columns are taken are put in this clause.

3. WHERE: any condition required to filter the output is put in this clause.

The query is explained below.

1. Find the number of male donors. Number of anything can be found using COUNT() function. A query is required since gender is included in deciding the type of donor.

2. The query is defined to find number of male donors as follows.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "M%"; )

3. In the previous query, LIKE operator is used since it is not defined what value is stored for male donors.

4. Similarly, the query to find the number of female donors is formed.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "F%"; )

5. Next, the final query is formed as follows.

SELECT: both COUNT() functions will come here.

FROM: table name

WHERE: specific blood group will be put here

GROUP BY: this clause is optional and is not used in this query.

HAVING: this clause is optional and is not used in this query.

6. The query after putting all clauses is shown below.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%"),

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%")

FROM DONOR

WHERE BG = xxx;

7. Alias is used in the above query for each column to get the final query.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors, COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Bess [88]

Answer:

Intranet

Explanation:

An organization owns a private network which is called an intranet. Private means that the network is accessible to all those employed within the organization, staff of the company.

Intranet exists only within the company and indicates the following.

1. The company establishes its own network inside the company so that the staff of the company can access and exchange information among themselves.

2. The staff can communicate and have discussions on the network.

3. The information is not accessible to outside parties such as customers, stakeholders, and others.

4. The network is not accessible and does not exists for the outside parties.

5. The term intra means inside and net means network.

Intranet leads to the following benefits.

1. The staff can view and exchange information with more ease and comfort and in less time.

2. Faster access to information increases employee output. Employees can perform better and have more time to focus on their work.

3. Communication among the employees is encouraged and made easy. Any one can communicate with every one in the company.

4. More communication leads to better working relationships among the staff. Cooperation and collaboration among the staff is given a boost.

5. Staff can give their input for the type of information to be held in the respository. This serves as the single point of information which enables smooth work flow.

Intranet also has some drawbacks.

The employees can take undue advantage of this communication channel for personal communications and information exchange.

Unproductive communication can only hamper the culture of the workplace.

Guidelines should be enforced to avoid unnecessary communication.

Technologies

Intranet can be implemented by using both local area and wide area networks ( LAN and WAN ). The infrastructure needed for the intranet includes the resources used in both LAN and WAN.
