2.The amount of data is large, such as tens of millions, and PostgreSQL is known as the benchmark for oracle, and it is still possible to process tens of millions of data, and it is also easy to learn and use.
3.The amount of data is average, such as millions, and MySQL is used for bridge shooting, and MySQL processing is relatively fast for this level of data.
4.The amount of data is small, for example, less than 100,000 Minxian, sqlite, and access are acceptable.
The above is the amount of data based on a single table operation, you look at the selection.

Anonymous users2024-02-03Establishment of the database: The design of the database only provides a description of the data such as the type, logical structure, connections, constraints, and storage structure of the data, which are called data schemas.
To set up a working database, the following needs to be done:
Various parameters of the selected database, such as maximum data storage space, number of buffers, concurrency, etc., can be set by the user or by the system at the default value. Define the database, use the data definition language and commands provided by the database management system to define the database name, data schema, index, etc. Preparing and loading data, defining a database is just a framework for a database, and a large amount of data must be loaded into a database to build a database.
In the process of data preparation and entry, it is necessary to take measures in technology and this cavity system to ensure the correctness of the loaded data, and the data that has been accumulated in the computer system should be fully utilized and converted into database data as much as possible.

If the customer needs to connect directly to the company's database to view and enter the data, then you need to write a web ** and publish it to the Internet through IIS. If, as you said, the field team returns to the company and then transmits the data to the company's server, then there is no need for it, and it is okay to write a Windows AP program in C.
In both cases, you do not need to install SQLSer on your computer. Because the database server is always on the company's server.

Anonymous users2024-02-01Do you need a database for the backend? If you don't need it, just simple bookkeeping, I suggest that Excel is the best tool, no need for other software, it can be done to count and record some data such as purchase, sale, inventory, cost, profit, depreciation, etc.
Using Excel well is equivalent to a small management software.

The database is generally composed of many tables, for example, the school builds a database, which can build a student table (including the student's name, age, student number, class, date of birth), a teacher table (including the teacher's name, age, teaching class, teaching category), a report sheet (including the student's student number, and the grades of each subject), etc. These are the ways in which the files are stored in the database, and try to make sure that the items in a table are closely related and have the same attributes, if this condition cannot be met, a table must be built (the redundancy of the built table has 4 levels). In order to meet the user's query needs, we also need to make a number of views, for example, you can make a view of his items have the name of the student, age, grades of each subject, and the teacher of each subject, etc., we can also export new items according to the existing items, for the purpose of simplicity, for example, the view can add an average grade, we add different permissions and roles to each view, and provide it to different people to query to protect the security of the database. >>>More
You can make an information query system, if you haven't done it before, it is recommended to use ASP to write it first, this is relatively simple, even people who do not have a basic knowledge of network programming can get started in a short period of time. The written web program can be called on the network, and different permissions can be set for different users. In this way, you can achieve the function you want, but this is only the basic, and you should learn more deeply to achieve more complete functions. >>>More
