After solving the problem of everyone's name, Wei Minsheng thought: At present, people are needed everywhere, and this way of conducting assaults like the past is not only very tiring for himself, but also easy to work in. At present, there are only a few dozen people, and if the development is stable in the future and the population from outside is absorbed, there will definitely be problems in management. From the perspective of the society in which I lived before, the most important thing in social management is population management, because population is the most basic element of society, if the population is not well managed, there will be various problems in other related affairs, in order to solve other management problems, we must invest a lot of manpower and material resources, resulting in a waste of social resources. Now that there is electricity and computers in my base, it is time to establish a basic population file, and slowly improve it while there are few people, so as to accumulate experience for future population expansion. I thought about the population management model in my own world, and felt that ZF was too much to manage, many departments worked independently, and information could not be shared, resulting in people doing something to prove and certificate. Although it does not go to the root, at least it reflects such a social phenomenon.

Since you are going to build a population management system from scratch, you need to take these problems into account and take measures in advance. The information on your world ID card includes basic information such as name, gender, photo, ethnicity, date of birth, identity number, address and fingerprints, as well as the time of issuance on the back.

Wei Minsheng thought: The ethnic policy over there has brought great unfairness to various ethnic groups and caused a lot of contradictions, and he must treat them fairly when formulating policies in the future, and there are no ethnic minorities, as long as there is only one ethnic group in his camp, that is, the Chinese nationality. In terms of policy, there is no preference for any ethnic group, and everyone is equal before the law, so the ethnic column is not considered.

In the case of the date of birth, the date information is already included in the identification number, so it is no longer a separate item. And there is no unified date and time in this world, at least the villagers in their base don't know what day their birth date is, and they all remember how many winters they have passed, that is, virtual years. Therefore, Wei Minsheng directly took the calendar of his world, determined the current day according to the situation of the moon and the absence, and started a new chronological method. If you don't know your date of birth, the middle eight digits are all the first day of the year according to the imaginary year. The first administrative division code directly uses 100001 to represent their first base, and the last three digits of the date of birth are the registration sequence code, which is also the male and female double arrangement, and the last digit is the check code. This coding method is very advanced, the number itself has a certain degree of anti-counterfeiting, and the most important thing is that Wei Minsheng can directly apply the relevant modules of the identity number verification process when asking others to develop a management system.

As far as the address is concerned, Wei Minsheng used to suffer from it, because of the address, not the local people want to apply for a temporary residence permit or residence permit, buy a new house or change the address of the job, the ID card has to be re-processed, it is simply a matter of labor and money, so he resolutely canceled this project on his own documents.

For the first time, Wei Minsheng found out when he counted relevant information that no one helped to go to the police station to cancel the household after many people died, so some of the data counted from the computer system were actually inaccurate, and the number was obviously greater than the actual number, which was easy to mislead the formulation of policies. Therefore, Wei Minsheng decided to verify the living status of the personnel from many aspects, and if they have not used their ID cards to handle their daily affairs for more than a year, the status of the personnel in the system will become unavailable, unless they go to the nearest population management department to reactivate them with their fingerprints, so as to ensure that there is no expired information in the population system.

Fingerprints are only used as a means of identity verification and exist digitally in the population system.

Through this simplification, Wei Minsheng's ID card is designed with only a few basic information: name, gender, photo and identity number. From Wei Minsheng's thoughts, this ID card is just the easiest way for the holder to prove his identity, but in the current world, if nothing else, the color photo on this card is almost impossible to imitate, at least for a long time. The knowledge that you spread in the other world is mainly controlled by the basic knowledge, and in the case that you have the backing of modern society, it is basically meaningless to climb the science and technology tree.

Wei Minsheng wants the vast number of working people, and only when they engage in production work will they create more social value. It has been said that war is the main driving force for social progress, and this is not bad if there is no technology to discover it on its own. But what technology you want, as long as you are financially abundant, what can't you buy. So Wei Minsheng doesn't want war, he just wants to develop peacefully, but in case there are some blind people who want to challenge their bottom line, Wei Minsheng has countless ways to make them disappear.

During the period when Wei Minsheng was building fortifications, Chen Xiaohua and his sisters purchased a lot of materials according to the procurement list, 20 computers and related network connection equipment have been in place, a set of solar power supply systems have also been supplemented, and some mobile houses, greenhouses and other materials have been purchased.

Arrange for the villagers to install solar panels, assemble the batteries themselves, and combine them with the original battery packs, and the two sets of power generation equipment share one battery pack to expand the storage capacity. The two inverters output different lines, the low-power one for lighting and the high-power one for power tools.

After connecting the power supply, Wei Minsheng found a mobile room, installed a few computers, called Xiaobao over, taught him a simple spreadsheet operation and pinyin input method, and asked him to enter all the basic information of the villagers into the spreadsheet according to the table of wages, forming an electronic document that is convenient for importing into the database in the future. Wei Minsheng used his mobile phone to collect photos of all the villagers, processed them into the same specifications as ID photos with PS, and stored them in the computer in the form of identity numbers.

With these basic information, Wei Minsheng spent a few more days designing a simple application of a desktop database with Access database, using identity numbers as associations, displaying basic information and photos in the form, and setting all the controls of the query form to be unmodifiable, preventing Xiaobao from accidentally modifying the data in the query operation.

After doing these things, Wei Minsheng gave each villager an electronic watch and a walkie-talkie after dinner, telling them the relevant knowledge of time division and how to use the walkie-talkie.
