Zhang Zhonghua's own office at the group headquarters has now been converted into a computer room, specially used to store his computers worth three million US dollars.
He also specially arranged a guard room on each side of the office. Five Jade Emperor security personnel were stationed in each guard room on duty, and they were rotated every day.
Although this large computer may not be sold on Hong Kong Island if it is stolen, it is worth three million U.S. dollars after all. If someone doesn't understand anything and just realizes that this thing is so expensive, it will definitely be sold.
The price was good, and then stupid thieves who organized a group to steal the computer stole it, or simply accidentally broke it, leaving Zhang Zhonghua with nowhere to cry.
Zhang Zhonghua in the computer room looked at the fax in his hand. The employees of the American Yuhuang Electrical Appliances Branch obtained the database-related patent information from the U.S. Patent Office and nodded with satisfaction.
The earliest version of the database, the mesh database management system (dbms), was successfully developed by General Electric Company in the United States in 1961. The ds database was the world's first mesh dbms and the first database management system to integrate data storage, laying the foundation for
The basis of the mesh database. ids has the characteristics of data schema and log, but it can only run on the ge host, and the database has only one file, and all tables in the database must be generated by manual coding.
Zhang Zhonghua looked at the leak-proof database and sighed, what the hell is this? In his previous life, he studied computer science concurrently when he was in college. Although he was not particularly outstanding, he still had a general understanding. This patent information was completely different from what was later published.
It’s not the same path. Doesn’t it mean that the patent of the future database belongs to you?
Thinking of this picture, Zhonghua got a little excited again. Now the industry is very profitable, and in the future real estate and finance will be very profitable, but the easiest way to make money is the computer network. Everything must be combined with the Internet.
Using what I learned in my previous life and my amazing programming and other skills, developing a database is still a piece of cake.
The development of database technology is an important part of advanced information technology and the foundation and core of modern computer information systems and computer application systems.
Database technology can be divided into three stages according to the development of data models: the first generation of networked and hierarchical database systems; the second generation of relational database systems; the third generation and later the most outstanding ones, which are mainly characterized by object-oriented models.
database system.
The first generation is represented by the hierarchical model database management system IMS developed by IBM in 1969 and the network model proposed by the database task group dbtg under Codasyl in the American database system language negotiation in the 1970s. The data model of the hierarchical database is rooted and directional.
Sequence tree and network model correspond to directed graphs. These two databases lay the foundation for the development of modern databases: they support three-level schemas (external schema, schema, and internal schema) to ensure that the database system has the physical independence of data and programs.
and certain logical independence; use access paths to represent the relationship between data; have an independent data definition language; and a navigational data manipulation language.
The main feature of the second generation database is to support the relational data model (data structure, relational operations, data integrity). Relational model: The concept of the relational model is single, and the connection between entities is represented by relationships; relational mathematics is used as the
Basics; the physical storage and access paths of data are opaque to users; the relational database language is non-procedural.
The third generation database was produced in the 1980s. With the continuous advancement of science and technology, various industries have put forward more demands for database technology. Relational databases can no longer fully meet the needs, so the third generation database was produced. Its functions are also more advanced.
Powerful: supports data management, object management and knowledge management; maintains and inherits the technology of the second generation database system; is open to other systems, supports database language standards, supports standard network protocols, has good portability and connectivity,
Scalability and interoperability, etc.
Today's ids database is still executed in the DOS window. Even if you develop the first-generation database yourself, you will probably need hundreds of tape storage, and there are not many companies and units that use databases now.
Currently, those who are qualified and capable of using databases are probably the military, followed by university laboratories, and then the world's giant companies.
No matter what, let's develop it first. The operating language of the database is determined by yourself. As long as you register a patent, you can almost unify the database market.
The U.S. government and military use it secretly without paying patent fees. Zhang Zhonghua has no choice but to use it. However, universities and giant companies must pay him for use, otherwise they will sue him to death.
Ugly Country is different now from when it dominated the world a few decades later. It is not so shameless. After all, it is only one of the two strongest countries, not one that will overtake them later.
As for the market prospects of the database, you don’t need to think about it. With such a perfect database, no one would be willing to redesign it by bypassing the patent, and it is also difficult to redesign it to avoid the one designed by Zhang Zhonghua.
Zhang Zhonghua feels that he can publish another database textbook. $3.40 per book is not expensive.
Zhang Zhonghua sat in front of the computer, stretched out, and was filled with joy when he saw the fruits of his labor these days. The compression software he wrote finally became famous, and the compression rate reached 100%.
The size of the software itself is 120kb, and it can only compress the formats that have appeared now, and other subsequent updates will be fine.
This compression software is definitely the pinnacle of this era, and you can make a lot of money just by relying on this software.
After having a simple lunch at the company, Zhang Zhonghua was about to return to the office and continue typing code. At this time, Zhang Zhonghua suddenly heard a noise coming from outside the building.
"Boss, there's a fight between two groups outside. Let me go and see what's going on."
While Zhang Zhonghua was wondering what was going on, Yin Ling opened the door and walked in and said worriedly.
"Let's go, I'll go up and have a look, and let An guard the door."
Zhang Zhonghua said helplessly. A group of idle people don't know what they are doing. The security of Hong Kong Island is getting more and more chaotic.
Zhang Zhonghua and Yin Ling waited in front of the electrical appliances. The elevators that came up were all full, and they seemed to want to go to the top of the building to watch the excitement. Zhang Zhonghua had no choice but to take Yin Ling down to the first floor by the elevator, and then
going up.
"Boss, you are smart. You don't have to wait for the elevator to go back and forth."
Yin Ling said with a smile.
Is this a trick that Zhang Zhonghua learned from the office workers in the building in his previous life? If there are too many people waiting for the elevator on the first floor, then climb the stairs to the second or third floor and take the elevator down and then go up again.
By the time the two reached the top floor, many people were already watching. The property management staff had no choice but to open the door to the top of the building. Countless people rushed to the rooftop, including some with telescopes. Well, including Zhang Zhonghua.
Zhang Zhonghua took a telescope and looked at a place not too far away in Yin Ling's somewhat resentful and offended eyes. He saw two dark groups fighting together. Steel pipe machetes were flying everywhere. From time to time, people were chopped to other places. Hong Kong Island Police
People from the police department also gathered not far away, seemingly preparing to wait until sufficient police force was assembled before entering the area to control the situation.
After watching for a while, Zhang Zhonghua returned to the company's office, but he couldn't continue typing code.
"Hong Kong Island is getting more and more chaotic. I don't know how long it will take for the situation to become clearer. Inform all stores to get off work early in the future. Let everyone pay attention to safety when commuting to and from get off work. Jade Emperor Security will also send some people to each store."
Zhang Zhonghua said helplessly.
Although Brother Lak is retired, he still controls the situation in Hong Kong Island. Brother K is putting pressure on the Hong Kong Island government to put the government on guard. After all, Hong Kong Island is one of the old and important taxing places in the UK and cannot be messed up.
After Brother K left for Canada, he should have completely stabilized.
In the blink of an eye, nearly a month passed. Zhang Zhonghua worked hard in the computer room for a month and finally completed the development of the database. He also adopted a relatively advanced window mode and perfect functions, which surpassed all current databases.
However, the current software takes up 6MB of space after installation and can only be used on industrial machines. Even after compression, it reaches 3.1MB and requires more than 30 tapes, which is enough to fill a new box.
Zhang Zhonghua went to the largest and most famous law firm in Hong Kong - the Law Firm founded by Mr. Luo Man Kam and his brother. The patent registration should be left to more professional people.
The Law Man Kam family is known as a legal family in Hong Kong and is one of the best in Southeast Asia.
Luo Man-jin is one of the few knights of the peace in Hong Kong. The Luo Man-jin family was one of the four major families in Hong Kong from the 1940s to the 1960s. Luo Man-jin once studied in England and majored in law. After graduating in 1915, he returned to Hong Kong to work as a lawyer. In 1916
Cooperated with Luo Wenhui to establish Luo Wenjin Law Firm. Luo Wenjin is a founding member of the Luo Wenjin family, the founder of the Asian Football Federation, a former member of the Municipal Council, and a member of the Executive Council and the Legislative Council.
The court battle over the Maolong suitcase made Luo Wenjin famous.
Accompanied by six bodyguards, Zhang Zhonghua went to the seventh floor of the Real Estate Building near the company. The law firm rented two spacious offices, which was a perfect symbol of strength.
The girl at the front desk was very surprised when she saw Zhang Zhonghua with 6 bodyguards in suits and leather shoes. She wondered why there was a lawsuit and so many people were needed to protect the client.
"Hello, sir, welcome to Luo Wenjin Law Firm. How can I help you?"
The front desk asked Zhang Zhonghua in a very professional and gentle voice, sweet and generous.
"Hello, I am Zhang Zhonghua from CFC Catering Company. I need to discuss business with your boss Luo Sheng. Is Luo Sheng convenient now?"
Zhang Zhonghua said.
In his opinion, it shouldn't be busy at this time, but he was a little embarrassed that he came directly to the door without making an appointment.
"Zhang Sheng, please wait a moment. Our boss Luo Sheng has just arrived at the company. Let me contact you first."
A minute later, Zhang Zhonghua entered Luo Decheng's office under the guidance of the receptionist. The receptionist made a cup of tea, closed the door and left.
While Zhang Zhonghua was sizing up Luo Decheng, Luo Decheng was also sizing him up.
Luo Luo Cheng is about 175 centimeters tall and has a well-maintained figure. His facial features are easy to identify and his eyes are very charming. Luo Luo Cheng's eyes always naturally show confidence. This is the confidence of an ace lawyer.
Mr. Lok Cheng, gbm, cbe, jp, is the president of the Hong Kong Lawyers Association and a member of the Executive and Legislative Councils. He is known as "Big Luo". When he was sixteen, Mr. Lok Cheng followed his father's path and studied law at Wharton College, Oxford University, England.
In 1960, after graduating from Oxford University and receiving a master's degree in jurisprudence, Lord Loch returned to Hong Kong, inherited the law firm founded by his father, became a partner and lawyer of the law firm, and served as a director of companies such as CLP, Swire and Wing On Bank.
In 1970, he became a member of the Hong Kong Municipal Council and entered politics. Apart from government affairs, Lord Lok was also a busy business man. He not only had to manage the law firm left by his father, but also served as a director of several large companies.
He was so happy that he owned a fortune of HK$4 billion.
In 1996, Lok Lok-cheng expressed his intention to run for the first chief executive. In 1995, he was the first to give up his British passport and receive a Chinese passport. However, he gave up due to insufficient support. After that, he quit politics and was among the first to be awarded the Grand Bauhinia Medal.
person.
"Sir Zhang, please sit down. I have admired you for a long time. How can I help you?"
Luo Luo Cheng asked curiously. Zhang Sheng has not been in any trouble recently, and most CFC restaurants have not heard of any lawsuits.
"Hello Luo Sheng, this time I want to entrust your law firm to help register two software patents in the United States. There may be a lot of trouble."
Zhang Zhonghua said politely.
This software patent will definitely have a lot to do with IBM. Whoever makes it first will own it, and IBM will definitely jump in during the patent publicity period.
"What type of computer software is it?"
Luo Luo Cheng asked curiously
He had read the big news reported in the newspaper last month. Mr. Zhang spent 3 million US dollars to purchase an IBM mainframe computer, which shocked many people in Hong Kong. Not long ago, two pieces of software were released. It seemed that
The speed is probably too fast.
"One is compression software, which compresses data and reduces the occupied space. This is not a big problem; the other database software is the key to the problem. It may be related to the American General Electric Company and IBM, and there should be some patent disputes.
.”
Zhang Zhonghua said and handed the relevant information to Luo Decheng.
Luo Luo Cheng is a barrister who graduated from Oxford, and his alumni and other connections are a hundred times stronger than his own. A small law firm has no confidence to go against the two giants. Moreover, as long as this lawsuit is fought, regardless of the final success or failure, Luo Luo Cheng will be famous overseas.
So Zhang Zhonghua is not afraid that he will not take over.
Luo Decheng took the two thick documents handed over by Zhang Zhonghua, and then opened the documents to read. Fortunately, the Chinese introduction saved a lot of trouble.
"Sheng Zhang, was this Chinese also typed by a computer?"
Luo Cheng looked at the document in his hand and asked in surprise. This is a great innovation in computers. If applied to a law firm, it would be much better than a typewriter.
"Yes, this is a Chinese input method I developed before. It is too inconvenient to use the computer without Chinese."
This lawyer has great eyesight and he saw the problem at a glance. Zhang Zhonghua was very satisfied in his heart.
"Then why didn't you apply for a patent for the Chinese input method?"
Luo Decheng asked. This patent is still very practical and can be used by many companies in Southeast Asia.
"It doesn't make much sense to apply for patent fees. There are not many companies using computers now, and computers are not cheap. Wait until there are more computer users before applying, so that the patent protection period can be longer."
