E-R method full name " Entity-Relationship method ", is mainly used in data division in design system.
What E-R figure adopted is rectangle and ellipse is to describe conceptual structure model in reality, and wherein rectangle represents entity, and ellipse represents entity attributes, the contact between rhombus presentation-entity.As shown in figures 10-14, described E-R methods analyst is:
User logs in needs creation database subscriber's meter, in order to verify log-on message.First the attribute that subscriber's meter has is user ID, and as the major key of this database table, the attribute that then Ku Biao also needs comprises address name, the type/authority of login password and user.These attributes do not allow for sky.
Personal information display then needs the personal information showing user, needs creation database student to show, record student information.The major key of student's table is student ID, and all the other attributes comprise specialty, phone, name, student number and I.D., and wherein specialty and phone allow for sky, and other attributes do not allow for sky.
Personal information display needs the personal information showing user, also needs creation database teacher to show simultaneously, record teacher's information.The major key of teacher's table is teacher ID, and all the other attributes comprise institute, name, and employee number and I.D., these attributes do not allow for sky.
Then curriculum information display and curriculum information inquiry all need creation database curriculum schedule, are the operating main bodies realizing curricula-variable function.The major key of curriculum schedule is course ID, and the attribute that also should have is course name, credit, the class period, place of attending class, teacher ID and measuring after school.These attributes do not allow for sky.
Be finally the required database curricula-variable table created of function of curricula-variable operation, the curricula-variable relation of curricula-variable table main manifestations student, has the relation of n:n, and the major key of curricula-variable table is curricula-variable ID, determines primarily of student ID attribute and course ID attribute.
Between database table, relation is set to:
Subscriber's meter uses when acting on logging in system by user, is student or teacher according to the authority recognition user of user, redirect student's personal information center or teacher's personal information center when user's Successful login.
The personal information of student's table record student, student ID is the major key of this database table, and student number can as external key.
The personal information of teacher's table record teacher, teacher ID is the major key of this database table, and employee number can as external key.
Curriculum schedule, as main database table, comprises all curriculum informations, is the carrier of most of functional realiey, searching of course, and shielding etc. is all by realizing the retrieval of curriculum schedule.
Curricula-variable table acts on student and carries out curricula-variable operation and deletion action, is the final target of Course-Selecting System.Curricula-variable operation the increasing newly namely to curricula-variable table of student, curricula-variable journey has been deleted is then realize the deletion action of curricula-variable table data item.
The Servlet routine package of this Mobile Elective System containing LoginServlet, Query, Delete, Show and Elective five classes, these five roughly the same time inherit HttpServlet class.The functional description of these five classes is as follows:
LoginServlet class: for receiving and return the logon information of user.
Query class: for receiving the request that user inquires about course, return the corresponding data message of user.
Delete class: for receiving the removal request of user to curricula-variable journey, returning user and whether having deleted successful corresponding information.
Show class: for receiving user to display or the request refreshing all optional courses, return the corresponding information of user.
Select class: for receiving the curricula-variable request of user, returns user's whether successful relevant information of curricula-variable.
Database interactive program is the kernel program of server, comprises Link, LogIn, Query, Show, Select and Delete six methods altogether.Functional description is as follows:
Link method: by JDBC connection data storehouse.
LogIn method: whether legal by the identity of the validation-cross user with database.
Query method: by with data can the condition query that provides of mutual basis go out the course that user needs.
Show method: by providing current all alternative curriculum informations with the mutual of database to stepping on user.
Select method: by preserving with the friendship user for each other of database the curricula-variable information selected.
Delete method: by specifying by the curriculum information selected with the mutual user of deletion of database.
JDBC operating database is used mainly to comprise following 3 steps:
1. load JDBC driver:
Realized by the static method forName () of Class class, parameter is determined by database supplier.
staticStringdriverName="com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(driverName);
2. creation database connects:
Call the getConnection () method of java.sql.DriverManager, obtain a Connection object, this object represents the connection of a database.
staticStringurl="jdbc:sqlserver://ZHANG-PC\\SQLEXPRESS;databaseName=cDB";
staticStringuserName="sa";
staticStringpassword="admin";
Connectionconn=null;
conn=(Connection)DriverManager.getConnection(url,userName,password);
3. discharge DataBase combining:
Create after using JDBC object and should close database connection object, the resource of release JDBC.Compare the order of establishment, just in time contrary during releasing resource.
publicstaticvoidfree(ResultSetrs,Connectionconn,Statementstmt){
try{
if(rs!=null)rs.close();
}catch(SQLExceptione){
e.printStackTrace();
}finally{
try{
if(conn!=null)conn.close();
}catch(SQLExceptione){
e.printStackTrace();
}finally{
try{
if(stmt!=null)stmt.close();
}catch(SQLExceptione){
e.printStackTrace();
}
}
}
Android client mainly comprises 5 pages, login page, the personal information page, curriculum information display page, curriculum information query page and the display of curricula-variable journey and the deletion page
Login page: for logging in system by user.Whether the information simultaneously detecting user's login is empty or legal.
The personal information page: the personal information this page showing user, and have some menus connections, the operation that oneself will complete is selected for user.
Curriculum information display page: this page shows current alternative all curriculum informations, user can need to find all courses or screen by oneself.
Curriculum information query page: this page is used for providing user to carry out query manipulation to curriculum information database.
Curriculum information display and delete the page: this page by list user all select curriculum information, and provide user to delete the operation of curricula-variable journey.
Wherein, " course shielding " function adds " shielding " button realization after the curriculum information item that curriculum information display page shows.
Employing LogIn, Query, Delete, Show and Select five classes in the Servlet programming of server comes with database mutual, and the data that database receives are processed, finally the result of process is returned to client, and in the relevant information that server end printing user asks.
Wherein Query(shows curricula-variable information) correlative code of class is as follows:
try{
Connectioncon=DriverManager.
getConnection(dbURL,userName,
userPwd);
Statements=con.createStatement();
ResultSetifyixuanke=s.executeQuery(sql);
while(ifyixuanke.next()){
Ifhas=ifyixuanke.getString (" whether curricula-variable ");
}
s.close();
if(ifhas.equals("t")){
PreparedStatementchaxun=con
.prepareStatement (" select course ID, course name, the credit class period, place of attending class, teach teacher ID, amount from curriculum schedule where course extracurriliar number=(select course from curricula-variable table where student number=) ");
Query.setString(1,username);
ResultSetkch=Query.executeQuery();
while(kch.next()){
Re=" t "+" "+kch.getString (" course name ")+" "+kch.getString (" class hour ")+" "+kch.getString (" credit ")
+ " "+kch.getString (" curriculum character ")+" "
+ kch.getString (" Assessment ")+" "+
Kch.getString (" term ");
}
ifkx="f";
Query.close();
}
else{
System.
out.println (" you also do not have curricula-variable! ! ");
ifkx="t";
re="f";
}
con.close();
}
catch(Exceptione){
System.
out.println (" connection data storehouse failure! "+e+ " false ");
re="f";
}
returnre;
}
The correlative code of other several classes and the similar of Query class, just the Select statement of relevant sql is different, only provides the Select statement relevant to class below.
The Select statement that LogIn class is relevant is as follows:
ResultSetyhb=login.executeQuery (" select student number, password from subscriber's meter ");
The Select statement of Delete class is as follows:
PreparedStatementsc=con.prepareStatement (" deletefrom curricula-variable table where student number=");
The Select statement of Show class is as follows:
ResultSetrs=xs
.executeQuery (" select course ID, course name, credit class period; place of attending class, teach teacher ID, measures after school; teacher's name, and affiliated pastern from curriculum schedule, teacher's information shows where curriculum schedule. course number=teacher's information's table. and course number ");
The Select statement of Select class is as follows:
PreparedStatementtianjia=con
.prepareStatement (" insertinto curricula-variable table values () ");
Android is integrated with ApacheHTTP client, uses HttpServletRequest and HttpServletResponse to represent request and response in server S ervlet programming.Request and response encapsulate by ApacheHTTP, then corresponding different requesting method, use HttpGet and HttpPost two objects.Wherein, HttpResponse is response object, uses DefaultHttpClient to perform request and obtains.
Realize the core code of this module:
publicclassHttpUtil{
