Example 2

(1) The starting steps are as follows: before the school day starts, all management terminals collect recommendation information of the term rules, generate recommendation term rules of each term rule based on the recommendation information of each term rule weighted average and rounding up, collect to obtain total recommendation term rules, and store the total recommendation term rules in a term management system. The actual calculation of the time limit is based on the result as an integer, and the time limit which is not an integer after all does not meet the general knowledge and is not convenient to understand, manage and transfer, for example, the time limit for uploading the operation is 14, 16, 18 days and the like.

(2) A confirmation step: opening the access of all student terminals and teacher terminals, collecting suggestion information given by the total suggestion period rules, carrying out weighted average and rounding to generate additional suggestions for prolonging or shortening each period rule; and generating an additional suggestion report and sending the suggestion report to each management terminal. And (3) repeating the step (1) again from all the management terminals which read the additional suggestion report to obtain the total term rule and store the total term rule in the term management system. Such an extended or shortened term is recommended to be, for example, +1, +3, +5, +7, +9 days, or-2, -4, -6, -8 days. And may also be measured in hours.

(3) A monitoring starting step: after the school period starts, storage positions of all documents, videos and homework files to be submitted are reserved in a course information storage, the deadline date of each document or video needing to be submitted by a teacher, the deadline date of each uploaded document and video needing to be watched by students, the deadline date of each homework file needing to be submitted by students and the deadline date of each submitted homework file needing to be amended by the teacher are obtained according to a total deadline rule, and the storage positions are stored in the storage positions of the corresponding documents, videos and homework files, and the storage positions further comprise corresponding teacher information and student information of the documents, videos and homework files. The expiration date is usually used with the day as the minimum calculation unit. Such monitoring specifically means that a change in state as desired is found by a query with respect to a document, video, job, or a new document is uploaded or stored, an event is considered to have been executed within a monitoring period, and otherwise, monitoring is considered to be still needed.

(4) A monitoring period report generation step every period: in a period of 12h-48h, the storage position of each document, video and homework file is inquired at the beginning of each period, the monitoring period which should be transmitted to students or teachers is confirmed, the monitoring period is sent to the period information form of each corresponding student or teacher, a new notice is inquired, the monitoring period is sent to each period information form, and a new message is inquired, and the monitoring period is sent to the period information form of the corresponding teacher. This cycle is most commonly used at 24h, and within a single table, every monitoring period that actually occurs is recorded, as well as the actual occurrence and completion times, and whether completion is complete, whether completion is overdue or not. To facilitate querying at any stage. Whether the expiration date is recorded can be actual days, or the expiration date can be recorded and transmitted by a pre-agreed code, for example, the expiration date is A, B within 3 days, C within 3-6 days, D more than 6 days, and the like.

(5) A monitoring report transmission step: and (4) after the step (4) is finished, sending each deadline information form with the content not being empty to the corresponding student terminal or teacher terminal, and sending a mail containing the deadline information form to a reserved electronic mailbox of the student or the teacher. When the student terminal or the teacher terminal receives the deadline information form, all the students or the teacher terminal must read and confirm the deadline information form to perform other operations; and recording actions performed within all time limits to a time limit information storage to form a time limit event set, and recording actions performed after all time limits are exceeded to the time limit information storage to form an time limit event set. And each event record in each closing event set or overdue event set establishes mapping with the original time limit information form of the students or teachers, so that query and confirmation are facilitated.

(6) Repeating the monitoring step: repeating the steps (4) to (5) until the school term is finished in the whole school term, generating an overdue event report of part of students by all the overdue events based on the mapping of the relevant students, and sending the overdue event report to the corresponding student terminals; generating an overdue event report of part of teachers based on the mapping of all the overdue events and relevant teachers, and sending the overdue event report to corresponding teacher terminals; and generating a total overdue event report by mapping all the overdue events with relevant students, teachers and courses based on the statistical information, and sending the total overdue event report to all the management terminals. The teacher's overdue event report and the student's overdue event report are basically only provided by the teacher, and can also be sent to other students or teachers under specific conditions. The total overdue event report can be designed into a hierarchy, and management terminals with different authorities can view the total overdue event report in different ranges.

Further, the action record in the step (5) includes that the learning of the document is started and the learning of the document is finished, the job is successfully submitted, the video is successfully downloaded, the reading is informed to be successful, the document is successfully uploaded, the video is successfully uploaded, the job correction is finished, the new job document is uploaded, and the message is completely checked; the period of the step (4) is 24 hours.

The administrator may view the comments.

System testing is the last step in system development, and the most common tests are divided into two categories: black box test and white box test. The black box test does not need to see the code problem any more, the debugging operation is carried out after the system does not report errors, and each function point developed by people is tested to find whether the verification problem and other input and output problems exist. The white box test is more logical, needs to study the logical structure problem in the code, does not need to see the interface and the debugging result, the system is like an opened box, all the logical paths of the system are tested by the method, and whether the finally tested state is consistent with the originally expected state is determined by checking the states of the system at different structure points.

Test environment, software environment: based on the system in the environment above windows 7; MYSQL; MYECLIPSE, hardware environment: CPU 1G Hz above, memory 1G, operating system: microsoft windows xp professional 2002, test range: and (5) a system function module.

Interface testing is also important in overall system testing. The first is the interface intuitiveness, e.g., whether some functions are redundant, whether the system interface layout is comfortable for the user, whether there are wrongly written or not, etc. Secondly, whether the system interface is easy to use and whether each function is clear at a glance is determined. The design of the interface is to attract the eyeballs of readers or users, and the frequently used things and the important contents are placed in the prominent positions. This interface is also somewhat frustrating if the system interface does not provide a comfortable use and utility to the user.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
