请写出一个基于MVVM的个人信息管理系统的设计与实现的程序代码

好的，以下是一个简单的基于MVVM架构的个人信息管理系统的程序代码示例（使用Vue.js框架和Element UI库）：

HTML代码：

<div id="app">
  <el-input v-model="searchKeyword" placeholder="请输入关键字搜索"></el-input>
  <el-table :data="tableData" style="width: 100%">
    <el-table-column prop="name" label="姓名"></el-table-column>
    <el-table-column prop="age" label="年龄"></el-table-column>
    <el-table-column prop="address" label="地址"></el-table-column>
    <el-table-column label="操作">
      <template slot-scope="scope">
        <el-button type="primary" @click="handleEdit(scope.row)">编辑</el-button>
        <el-button type="danger" @click="handleDelete(scope.row)">删除</el-button>
      </template>
    </el-table-column>
  </el-table>
  <el-dialog :visible.sync="dialogVisible">
    <el-form :model="editForm" ref="editForm" :rules="rules" label-width="100px">
      <el-form-item label="姓名" prop="name">
        <el-input v-model="editForm.name"></el-input>
      </el-form-item>
      <el-form-item label="年龄" prop="age">
        <el-input v-model="editForm.age"></el-input>
      </el-form-item>
      <el-form-item label="地址" prop="address">
        <el-input v-model="editForm.address"></el-input>
      </el-form-item>
    </el-form>
    <div slot="footer" class="dialog-footer">
      <el-button @click="dialogVisible = false">取 消</el-button>
      <el-button type="primary" @click="handleSave">确 定</el-button>
    </div>
  </el-dialog>
</div>

JavaScript代码：

var app = new Vue({
  el: '#app',
  data: {
    tableData: [
      { name: '张三', age: 20, address: '北京市海淀区' },
      { name: '李四', age: 25, address: '上海市浦东新区' },
      { name: '王五', age: 30, address: '广州市天河区' }
    ],
    searchKeyword: '',
    dialogVisible: false,
    editForm: {
      name: '',
      age: '',
      address: ''
    },
    rules: {
      name: [
        { required: true, message: '请输入姓名', trigger: 'blur' }
      ],
      age: [
        { required: true, message: '请输入年龄', trigger: 'blur' }
      ],
      address: [
        { required: true, message: '请输入地址', trigger: 'blur' }
      ]
    }
  },
  methods: {
    handleEdit: function(row) {
      this.editForm = Object.assign({}, row);
      this.dialogVisible = true;
    },
    handleDelete: function(row) {
      var index = this.tableData.indexOf(row);
      if (index !== -1) {
        this.tableData.splice(index, 1);
      }
    },
    handleSave: function() {
      this.$refs.editForm.validate(function(valid) {
        if (valid) {
          if (this.editForm.id) {
            var index = this.tableData.findIndex(function(item) {
              return item.id === this.editForm.id;
            }.bind(this));
            if (index !== -1) {
              this.tableData.splice(index, 1, this.editForm);
            }
          } else {
            this.tableData.push(Object.assign({ id: Date.now() }, this.editForm));
          }
          this.dialogVisible = false;
        } else {
          return false;
        }
      }.bind(this));
    }
  },
  computed: {
    filteredTableData: function() {
      return this.tableData.filter(function(item) {
        return item.name.indexOf(this.searchKeyword) !== -1 || item.address.indexOf(this.searchKeyword) !== -1;
      }.bind(this));
    }
  }
});

这个示例实现了一个简单的个人信息管理系统，包括查询、添加、编辑和删除个人信息的功能。其中，数据模型和业务逻辑都被封装在视图模型中，用户界面则通过Vue.js框架和Element UI库进行实现。
