A, check the weight machine using principle:
After sorting out the book information in the library, download it to the collector. When the teacher goes out to buy, he only needs to bring the collector, which can realize the functions of checking duplicate and buying books.
Second, the collector using process:
1. Before going out to buy, sort out some information about the books in the collection and download them to the book collectors.
2. When purchasing on site, the teacher only needs to enter the purchasing interface according to the corresponding prompt of the collector program and scan the ISBN number of the book he wants to buy. Collectors will check the ISBN accordingly. If a book with ISBN number already exists in the library, it will give some information about the ISBN number of the library, such as the title and quantity. Teachers can use this information to decide whether to buy this book and how many copies to buy.
3. After purchase, upload the purchased order file to the computer, and the order file will be automatically generated.
Third, about data collation:
In the whole system, the more complicated part is the data sorting part.
Due to the different management software and user rights of each library, the exported data is very different, but it can be roughly divided into the following categories:
Data in 1 MARC format: This format belongs to the standard format of book information and is supported by almost all book management software. Therefore, most libraries can export data in this format.
2.Excel format: At present, many programs support the import and export of spreadsheets.
3.TXT text file: Almost all book management software supports the export of this format.
4. Database files: Book management software itself belongs to database management, so it can easily export various database formats. Such as: *. Dbf format, *. Mdb format (access database).
This software can directly handle the above formats. For database files, because the formats of each database are inconsistent, they can all be exported as spreadsheets and text files. So we didn't develop the function of directly processing the database, so we asked users to export it as a spreadsheet or a text file.
1. For MARC data, it should be noted that the number of copies belongs to a user-defined field, and the definitions of each library are inconsistent, so the user can choose, and the default number of copies can also be selected.
2. For EXCEL files, please indicate the column where the extracted fields are located and the range of collation. Users only need to open the spreadsheet to view it.
3. For TXT files, the format requirement is: one message per line, and each field is separated by spaces or TAB keys by default. Delimiters can be specified by the user.
