The customer has a system that is frequently connected to us to query data.
The previous practice was to give the other party an account so that he could connect to our database for query.

Therefore, early colleagues really gave them DB link strings
The customer's Windows programs and websites are connected to our company's DB in such a dangerous way.

But I think everything is dangerous, and ......
Isn't the performance worse if the other side's SQL commands are messy?
If the other party is not careful, the configuration file is stolen. What should I do if I see my DB Connection String?
A few years ago, the Internet was not that large in bandwidth, so there were various restrictions to prevent them from querying too much data at a time.

After I took over the Service, I switched to Web Service (WS-*). I have introduced several articles before.
I did not expect that the year 78 has passed.

Interesting. In the past few years, the highest traffic or reading rate on my website was: Searching for the keyword "Web Service" and connecting to my website.

Later, the customer imported the telephone voice card (CTI)

That is, we call a bank or credit card company to perform the following operations on the voice system on the phone:
Click 1 to help you query the bill amount
Press ii to help you do XYZ and so on
Press "9" to help you transfer a person.

You beat me up, and I don't know the CTI phone voice card or phone switchboard.
Then how can I work with the vendor? How to exchange data?

The vendor asked me: is it possible to connect Socket?
I won't.

I asked him: Can your CTI be connected to the network? Can I send and receive webpage information?
The vendor said yes.

Therefore, we can achieve today through Web Service.

 

Last year, the system was changed to a Mobile APP (Mobile phone and tablet) interface.
What about me? How can I modify it together?

No, I have nothing to do. I am in a daze. I will test it with me after the manufacturer has written it.
Then it went online.

Then, inexplicably, it turns into the first set of operational functions of this department.
The boss is happy to show off with others.
(I did nothing. What is the result? Everyone is very happy, including me, partners, bosses, and customers)

A university teacher talked to me a few days ago and said that front-end technologies are currently popular and everyone is working on mobile apps.
He worried: With the picture, who will feed the information? Who is responsible for providing data to these apps?
(This means that everyone is engaged in mobile apps and mobile games. It seems that no one wants to create backend and database programs)

I told him, that's good. No one will do it. Just do it for me.
If I am not interested in front-end technologies, I will focus on data mining, data transmission, and providing their (various front-end technologies) data.

They (various front-end technologies) are responsible for "image" Display
I am responsible for "Data Access"

This is awesome and everyone has a job.
Unlike in the past, pictures were not easy to see, color, UI ...... the other party GGYY had been around for a long time, but it was not my expertise. I could not satisfy each other's aesthetics.

Finally, it is out of touch with the annoying "image" and "UI ".
I just breathed a sigh of relief

This means that I don't need to answer the End User's complaint phone number. In the future, they will complain about incoming calls. At most, the data I gave is incorrect.
(Although the data is wrong, it is very serious, but at least I am familiar with this piece, it is better to grasp the problem)

The User will no longer complain about the problem of "screen", the font size, the UI is not smooth or hard to see
(I can't do anything about front-end images)

 

I used to think it was strange to write an ActionScript program to generate Flash Animation and AIR,
Why does their program have no link to the database?

Later, they discovered that they handled the problem through Web Service, turning "image" into "image" and "Data Source" into "Data Source 」
In fact, the distinction is very clear.

 

We used to write web pages.
In the future, we can say that we provide "data" and "services ".

Web Service/WCF Service/WebAPI saves our lives and continues the lifecycle of our (Web application ).
