5 Detailed design of document retrieval system
5.1 Database design
In the overall design stage, the solution to the problem is put forward in a more abstract and general way . The task of the detailed design stage is to concretize the solution , That is to design the database, compile the program and realize the whole system module .
The following describes the functions of each table ：
（1） Administrator table （Admin） Used to save the administrator name and password , The structure is shown in the table 5-1 Shown ：
surface 5-1 Administrator table Admin
Field name data structure Primary key describe
Aid int yes Administrator number
Aname Varchar(10) no Administrator name
Apwd Varchar(50) no password

（2） Document information table （Book）： Details of the documentation used to store , Its properties are defined by “ Document number + Document title + The author's name + keyword + Abstract + Time of publication + Journal name + Time of publication + classification ” form , As shown in the table 5-2 Shown ：
surface 5-2 Document information table
Field name data structure Primary key describe
Bookid int yes Document number
Author Varchar(50) no The author's name
Bookname Varchar（100） no Document title
Keywords Varchar(50) no keyword
Abstract Varchar(50) no Abstract
Pubtime datetime no Time of publication
Qkname Varchar(200) no Journal name
Location Varchar(200) no Document storage path
Xzcount Int no amount of downloads
Code Char(10) no Title initials
Class Varchar(50) no classification
（3） Document category table （Class）： This table is used to store the existing literature classification information , The document category attribute in this table should refer to the category field in the document information table , Its properties are defined by “ Category number + Category name ” constitute , As shown in the table 5-3 Shown ：
surface 5-3 Category information table
Field name data structure Primary key describe
Cid int yes Category number
Cname Varchar(10) no Category name

（4） User type table （Users）： This table is used to store user related information , Such as user name , password , mailbox , Telephone and other data . The specific structure is shown in the table 5-4 Shown ：
surface 5-4 User information sheet
Field name data structure Primary key describe
Uid int yes The user id
Uname Varchar(10) no User name
Upwd Varchar(50) no User password
Uemal Varchar(50) no User mailbox
Utel Varchar(50) no You phone

（5） Discussion topic table （Topic）： This table stores information about the discussion topics in the discussion area , Include the user name of the published topic 、 Topic topic 、 Content 、 Creation time 、 user IP Address and other fields . The specific structure is shown in the table 5-5 Shown ：
surface 5-5 Discussion topic table
Field name data structure Primary key describe
TopicID int yes Subject number
UserLoginName Varchar(20) no User name
Title Varchar(50) no subject
Content Varchar(50) no Content
CreateTime Varchar(50) no Time of publication
IP Char(15) no user IP Address

（6） Subject Reply Form （Reply）： This table stores information about replies to all topics in the discussion area , Include the subject you replied to ID、 User name to post the reply 、 Reply to the question 、 Content 、 Creation time 、 user IP Address and other fields . The specific structure is shown in the table 5-6 Shown ：
surface 5-6 Subject Reply Form
Field name data structure Primary key describe
ReplyID int yes Reply No
IP Char(15) no user IP Address
TopicID int no Subject number
UserLoginName Varchar(20) no User name
Title Varchar(50) no subject
Content Varchar(50) no Content
CreateTime Varchar(50) no Time of publication

The relationship between the main tables ： Use SQL Server2005 The design is shown in the picture 5.1 Diagram of the table shown in , The corresponding primary key and foreign key constraints are shown in the figure .

chart 5.1 A diagram of the relationships between tables in a database
5.2 Directory structure
admin： Background operation script for storage system administrator , Including login 、 New category 、 Document management 、 Upload documents and other functions .
admin- The literature ： A catalogue for storing documents .
App_Code： It includes two general modules: database link and user registration .
App_Data： It's used to store the database .
css： The storage control page displays the controlled css Style sheets .
discuss： Store relevant pages and code files of the discussion area .
Images： Used to store image files in the website display .
js： Storage is used to control the display of document information javascript Script files .
myControls： Store user-defined controls , A directory navigation bar control .
