期中考試--人口普查
阿新 • • 發佈：2020-12-19
第七次全國人口普查登記
1、專案需求：
開展第七次全國人口普查，將為編制“十四五”規劃提供重要資訊支援；推動實現人口與經濟社會、資源環境協調發展，為深化供給側結構性改革，推動經濟高質量發展，建設現代化經濟體系提供強有力的支援；人口普查還將為完善人口發展戰略和政策體系，促進人口長期均衡發展提供重要資訊支援。
2.系統要求與功能設計
2.1 頁面功能要求
（1）能夠在Tomcat伺服器中正確部署，並通過瀏覽器檢視；（1分）
（2）網站頁面整體風格統一；

（3）主頁面：要求顯示人口登記、修改人口資訊、刪除人口資訊、查詢人口資訊，人口資訊瀏覽五個子選單。（1分）
（4）人口登記頁面：（6分）
①完成新增人口資訊登記，基本資訊和填報限制如下表所示
|
戶 別 |
家庭戶 集體戶（單選框） |
|
住房型別 |

|
本戶現住房面積 |
XXXXX平方米（文字框，只能輸入這個整數） |
|
本戶現住房間數 |
XXXXX間（文字框，只能輸入這個整數） |
|
戶主姓名 |
XXXXX（文字框） |
|
身份證號碼 |
XXXXXXXXXXXXXXXXXX（判斷身份證位數13位並且只能錄入數字、最後一位可以錄入X） |
|
性別 |
男/女（單選框） |
|
民族 |
（文字框） |
|
受教育程度 |

②點選“提交”按鈕，儲存成功則跳轉到人口基本資訊瀏覽介面，新錄入的資訊置頂顯示。失敗則提示錯誤資訊，返回當前頁面
評分標準：
①完成人口登記頁面（未完成0分，完成1分）
②儲存人口資訊入庫（未完成0分，完成1分）
③戶別、住房類別、性別實現一個單選框錄入0.5分，全部實現1分。（未完成0分，完成一個0.5，全部完成1分）
④本戶現住房面積或本戶現住房間數實現整數判斷（未完成0分，完成0.5分）
⑤判斷身份證按照要求錄入，實現位數和數字錄入判斷0.5分，實現最後一位可以輸入數字或X判斷0.5分。（1分）
⑥受教育程度下拉框錄入（未完成0分，完成0.5分）
⑦提交後頁面跳轉功能；（未完成0分，完成1分）
（ 5）修改人口資訊頁面：（3分）
輸入戶主姓名，顯示其餘資訊，可對身份證號碼、性別、民族、受教育程度進行修改。（身份證號碼、性別、受教育程度必須符合錄入要求）；如果該名戶主資訊資料庫不存在，則提示“該戶主資訊不存在”。（3分）
評分標準：
①完成修改戶主個人資訊頁面（未完成0分，完成0.5分）
② 實現資料庫中資訊更新（未完成0分，完成1分）
③修改資訊判斷是否符合要求。（未完成0分，完成0.5分）
④輸入姓名，顯示其餘資訊，若該資訊不存在，提示錯誤資訊；（未完成0分，完成1分）
（6）刪除人口資訊頁面：錄入戶主姓名，顯示詳細資訊後，點選“刪除”按鈕，彈出提示框，提示“是否確認刪除該戶主資訊”，確認後刪除該資訊。（1分）
評分標準：
①輸入戶主姓名可顯示其餘資訊。（未完成0分，完成0.5分）
②對應刪除資料庫中資訊（未完成0分，完成0.5分）
（7）瀏覽人口資訊頁面：（2分）
以列表形式顯示人口基本資訊，結果列表中顯示姓名、性別，民族、受教育程度基本資訊，點選姓名，可以跳轉到個人詳細資訊。
①實現以列表形式顯示人口基本資訊，結果列表中顯示姓名、性別，民族、受教育程度基本資訊（未完成0分，完成1分）
②實現跳轉個人詳細資訊頁面。（未完成0分，完成1分）
（8）查詢人口資訊頁面：（3分）
要求可以根據人口姓名、性別、民族、受教育程度四種條件實現模糊查詢，輸出結果以列表形式顯示，顯示人口姓名、性別、民族、受教育程度基本資訊，點選列表中的姓名，跳轉到人口個人詳細資訊頁面。
評分標準：
①缺少一種查詢條件扣除1分。（未完成0分，完成3分）
2.2 功能要求
