A PROPOSAL FOR AMANAGEMENT APPLICATION

FOR STUDENTS

ABSTRACT. In this paper we propose a web-basedapproach to management students in an educationalinstitution developed using MySQL database and PHPscripting language.

KEY WORDS: application, management, student

1. INTRODUCTIONThe idea was to use the resources each

department has and to present a practicalsolution with keeping security of the data inmind. Due to the constraints regarding the

budget on the project allocated until now and thetime frame for the project, one of the most

suitable solution was to use free open sourcesoftwares (Apache as a web server, MySQLserver as a backend database and php as a serverside language). These three programs will beinstalled on each machine in every department.Considering the complexity of configuringApache, MySQL and php, the solution is to useXAMPP

(http://www.apachefriends.org/en/xampp.html).

It is a free packaged preconfigured

Apache, MySQL, php bundle, which simplyneeds to be installed.Each department communicates to its

own local database via a web browser, so theycan insert, delete, update and select data via theweb browser. At every fixed point they make adump file of the data that are not updated to theMain database. This action is performed by firstcreating a duplicate of each table and insertingthem with all the data that has not been updatedto the Main until that moment. Which is known

from a column called copied (Boolean value), ifcopied 1 else 0. After the creation of new tables

and insertion of non updated data, this new tableis dumped into file using mysqldump command.

Acest lucru se realizeaz prin intermediulunui fiier batch, care creeaz fiierul deimagine memorie, fermoare fiierul icripteaz-l. Aceste date este acum gata

pentru a fi expediate la Main.Pe de altparte, Principal, decripteaz datele, unzipsea i de date este actualizat n baza sa dedate. Aceast aciune este, de asemenea,efectuat prin intermediul unui fiier batch,care recreeaz aceste tabel dump din

fiierul de imagine memorie.

This is done via a batch file, whichcreates the dump file, zips the file andencrypts it. This data is now ready to bedispatched to the Main.

On the other side, the Main,decrypts the data, unzips it and the data isupdated in its database. This action is also

performed through a batch file, whichrecreates these dump table from the dumpfile.

The application can be find at

http://www.runceanu.ro/adrian/gestiune/index.php.The application has two types of

users: students and administrator. Only theadministrator, in fact the assistant or theteacher who manage the database of projectsand students, has passwords for the access ona module in administration. Other users ofthis software, the students, have access onlyon the interface specifically intended forthem. After login in, a student will be able to

upload theme of the project and to view themarks given by a teacher at the laboratorywork and projects

For registration the student willhave to introduce in the form personal data

For each selected student may begiven a mark for a laboratory practice

theme paper. The number of laboratorythemes is established by the administrator.Clicking on the button "Add

- Adding a new project;- Allocating an existing project of a

student.

1. The adding of a new project can

be done in the first part of the page. Youcan add the name of the project (which

Alocarea unei teme de proiect unuistudent de poate face n cea de a doua partea aceleai pagini. Se poate alege numelestudentului care nu are niciun proiect alocatla momentul respectiv i denumirea

proiectului alocat. Ambele informaii(numele studentului i denumireastudentului) se selecteaz din dou liste

derulatoare.Ca observaie, am luat n calcul c unstudent care a primit un proiect s nu maiapar n lista derulatoare cu toi studenii

pentru a evita situaia n care acelaistudent primete dou sau mai multedenumiri de proiect.Asemntor, denumirile de proiecte care aufost deja alocate unor studeni, dispar dinlista derulatoare corespunztoare, pentru aevita situaia n care un proiect cu aceeaidenumire s fie alocat la doi sau mai mulistudeni.

Aplicaia "Sistem on-line deeviden a studenilor dintr-o facultate" afost implementat prin tehnologia PHP,tehnologie care permite o dezvoltare maisistematic a unei aplicaii cu baze de date.Ca Application Server am folosit Apache,

baza de date a fost MySQL, iar mediul de

should be different from the names ofexisting projects) and details of therequirements that need to be accomplished

by the project in teachers (assistants)vision, who established the theme of the

project.

2. Assigning a theme project to astudent can be done in the second part ofthe same page. It may be choose the nameof the student who has no project assignedat that time and the name of the project.Both information (student name and the

project name) are selected from twounrolled lists.

As an observation, we thought that

a student who has received a draft not toappear anymore in the unroll list of allstudents, to avoid the situation in which astudent receives two or more projectnames.

Also, the names of the projects thathave already been allocated to students,disappear from the appropriate unroll list,to avoid the situation where a draft of thesame name to be assigned to two or morestudents.

Clicking on the button "ProjectMarks" a mark can be give to a studentwho uploaded earlier the project themeallocated.

The professor (assistant) has theopportunity to download the *.zip archivefile which contain the solution proposed byeach student to the project which wasallocated and then to give you theconsidered mark.

3. PROGRAMMERS GUIDEThe application "on-line registration

system for university students" has beenimplemented by PHP technology, whichallows a systematic development of anapplication with databases. As we usedApplication Server Apache, the database isMySQL, environment and development has

been used Macromedia Dreamweaver 8.0.The application is a solution to keep

the record of students who participate to alaboratory.
