It small Li Chun--The factory model in pharmacies

in real life, there are many examples that allow us to understand design patterns well. They can actually tell us what the benefits of using design patterns are and what problems can be solved. Many books or articles explaining the design pattern are used more or less, which can make the description more vivid, shallow and easier to understand.

in order to better illustrate the design pattern, this article invented a hero Xiao Li, he is an IT designer, in order to survive, resolutely into the sea, and constantly use their IT experience, improve business. But there is a risk in the sea, so he constantly change his career (no way, not to change the profession to say not clear AH). The following is the beginning of the text, will not eunuch do not know, haha.

IT designer Xiao Li has been in it for many years, but the income is limited, it is difficult to mix in the IT sector, but also see no money, very dazed.

now, people pay more and more attention to health problems, unlike before, in the food is not full, wear clothes, who also tube is not healthy. Now around the neighborhood, that is a pharmacy, a pharmacy of two stores can even open to only a 3 -metre wide road, it is clear that the pharmacy business and profit is certainly good.

See selling drugs seems to be able to make money, decided to abandon it from the business. Will have many years of savings, opened a small pharmacy, and began to be both the boss and employees of the entrepreneurial process.

Early Start, Xiao Li is also more cautious, only to sell a few conventional Western medicine, such as the Tai, fast grams, UPM, ibuprofen and other family standing drugs. When a customer comes, according to the needs of the customer's medicine, he personally to the customer to take, run around. If it is expressed in code, it is roughly the case:

If ( customer wants to have a dick)

pick up the bar at the drug counter.

else if ( customer wants fast gram)

get The fast gram at the drug counter.

else if ( customer wants Finn)

......

in this way for a period of time, Xiao Li tired, a trip to a Bandi run, dry it , all day sitting in front of the computer, physical fitness early AH (so advise you it migrant workers, pay attention to exercise body ah, which days IT industry can not go down, or have the strength to do other migrant workers live, You say yes or no AH).

So, after earning the first bucket of gold, Xiao Li mercilessly heart, a few employees recruited, each responsible for a drug counter, when the customer wants some kind of medicine, Xiao Li only need to shout a voice, responsible for the drug counter staff will bring the medicine to him. Haha, Xiao Li more relaxed, the original to own full House run, now only need to shout a voice on the line.

In this case, the diagram shows that this is probably true:

Slowly, Xiao Li's business more and more good, but because every day to shout a voice, are fast mute, for this day to consume a lot of Golden voice throat treasure it. In addition, with the booming business, Xiao Li also boldly broadened the variety of drugs, so that users can give customers more choices, such as must be Jiahei, and so on. In addition, oneself how also is a small boss, always can not also want to oneself all day shout, do not know still think oneself is a man, not face ah. So, Xiao Li also recruited two drug managers, respectively, responsible for cold medicine and headache medicine, so Xiao Li can be at ease when the boss.

In this case, the diagram shows that this is probably true:

Now, Xiao Li just take the money, shout the voice of the matter, all to the drug manager to be responsible for ( the big deal to give them some benefits, a few boxes of the chest bao). For each drug manager, just tell the clerk in charge of the drug counter to get the medicine.

business on the track , and soon, Xiao Li is not satisfied with the status quo. Light selling Western medicine which line Ah, the Chinese and western combination is the focus. So, Xiao Li expanded the store, began to sell Chinese medicine. What Cassia, Angelica, Pinellia and so on also put a counter.

In addition, light sell medicine also not ah, competition is too fierce, if the pharmacy to ask a few physicians, may be more able to meet customer requirements, some small disease, directly look at, and then recommend drugs, but also to avoid users disorderly medicine.

To this end, also recruited several Chinese medicine dispensers, responsible for dispensing according to the doctor's prescription. The ability of Chinese medicine dispensers is different from Western medicine clerk, he needs to be able to dispense according to the prescription, different pharmacists, responsible for different types of prescriptions of pharmaceutical work.

In this case, the diagram shows that this is probably true:

Physicians are more powerful, may be recommended Western medicine, but also recommended Chinese medicine oh, charm ah. You have to ask, where's the drug manager? This ... , maybe go to the doctor's certificate?

As for Xiao Li's follow-up how, I do not know, haha, just wrote this.

( can you see these figures?) There is a far-fetched place, indulge understanding. I'm managernent, too. )
