CSharp: Divide and Conquer Algorithm

项目结构一个基于分治算法的珠宝销售管理实现。系统包含订单管理、权限控制、销售统计和风控预警等功能模块主要特点包括采用分治策略处理大规模销售数据实现并行门店业绩统计、时间维度报表生成月度/季度/年度和高风险订单筛查阈值10万元通过二叉树结构实现权限管理的分治查询支持功能权限校验和数据权限过滤核心类包括OrderRepository订单数据仓库支持按门店/月份拆分SaleStatDAC销售统计分治实现RiskOrderDAC风控分治检测PermissionDAC权限树分治校验4.演示了分治算法在商业系统中的典型应用场景包括并行计算、递归分解和结果合并等关键环节该实现展示了分治思想在处理复杂业务数据时的优势特别是对于需要多维度聚合分析和大规模数据过滤的商业系统具有参考价值。/* # encoding: utf-8 # 版权所有 2026 ©涂聚文有限公司™ ® # 许可信息查看言語成了邀功盡責的功臣還需要行爲每日來值班嗎 # 描述Divide and Conquer Algorithm # Author : geovindu,Geovin Du 涂聚文. # IDE : vs2026 c# .net 10 # os : windows 10 # database : mysql 9.0 sql server 2019, postgreSQL 17.0 Oracle 21c Neo4j # Datetime : 2026/07/05 22:16 # User : geovindu # Product : Visual Studio 2026 # Project : CSharpAlgorithms # File : Const.cs */ using System; using System.Collections.Generic; using System.Text; namespace CSharpAlgorithms.DivideConquer.Constants { /// summary /// /// /summary public static class Const { // 风控高客单阈值 10万 public const double RiskAmountThreshold 100000.0d; // 门店列表 public static readonly Liststring ShopList new() { 福田店, 南山店 }; // 季度对应月份 public static readonly Dictionaryint, int[] QuarterMonthMap new() { {1, new[] {1,2,3}}, {2, new[] {4,5,6}}, {3, new[] {7,8,9}}, {4, new[] {10,11,12}} }; // 品类 public static readonly Liststring CategoryList new() { 黄金, 钻石, 彩宝, 银饰 }; // 权限常量 public const string PermDiamondAdjust 钻石调价; public const string PermExportAllShop 全门店数据导出; public const string PermShopAdjust 本店调价; public const string PermModifyRole 修改角色权限; public const string PermViewSelfSale 查看个人业绩; public const string PermViewStock 库存盘点; } } /* # encoding: utf-8 # 版权所有 2026 ©涂聚文有限公司™ ® # 许可信息查看言語成了邀功盡責的功臣還需要行爲每日來值班嗎 # 描述Divide and Conquer Algorithm # Author : geovindu,Geovin Du 涂聚文. # IDE : vs2026 c# .net 10 # os : windows 10 # database : mysql 9.0 sql server 2019, postgreSQL 17.0 Oracle 21c Neo4j # Datetime : 2026/07/05 22:16 # User : geovindu # Product : Visual Studio 2026 # Project : CSharpAlgorithms # File : Order.cs */ using System; using System.Collections.Generic; using System.Text; namespace CSharpAlgorithms.DivideConquer.Entity { /// summary /// 珠宝销售订单 /// /summary public record JewelryOrder { public string OrderID { get; set; } public string ShopName { get; set; } public int SaleMonth { get; set; } public int Quarter { get; set; } public string Category { get; set; } public double SaleAmount { get; set; } public double Profit { get; set; } public string SellerID { get; set; } } /// summary /// 销售汇总统计支持加法合并 /// /summary public class SaleSummary { public double TotalSales { get; set; } public double TotalProfit { get; set; } public double Gold { get; set; } public double Diamond { get; set; } public double Gem { get; set; } public double Silver { get; set; } /// summary /// 合并两份统计结果对应分治Combine /// /summary public SaleSummary Add(SaleSummary other) { return new SaleSummary { TotalSales TotalSales other.TotalSales, TotalProfit TotalProfit other.TotalProfit, Gold Gold other.Gold, Diamond Diamond other.Diamond, Gem Gem other.Gem, Silver Silver other.Silver }; } /// summary /// 转字典用于打印报表 /// /summary public Dictionarystring, double ToDict() { return new Dictionarystring, double() { {总销售额, TotalSales}, {总毛利, TotalProfit}, {黄金, Gold}, {钻石, Diamond}, {彩宝, Gem}, {银饰, Silver} }; } } } /* # encoding: utf-8 # 版权所有 2026 ©涂聚文有限公司™ ® # 许可信息查看言語成了邀功盡責的功臣還需要行爲每日來值班嗎 # 描述Divide and Conquer Algorithm # Author : geovindu,Geovin Du 涂聚文. # IDE : vs2026 c# .net 10 # os : windows 10 # database : mysql 9.0 sql server 2019, postgreSQL 17.0 Oracle 21c Neo4j # Datetime : 2026/07/05 22:16 # User : geovindu # Product : Visual Studio 2026 # Project : CSharpAlgorithms # File : OrderBuilder.cs */ using System; using System.Collections.Generic; using System.Text; namespace CSharpAlgorithms.DivideConquer.Entity { /// summary /// /// /summary public static class OrderBuilder { /// summary /// 单条订单构建最小汇总Conquer结果 /// /summary public static SaleSummary BuildSingleSummary(JewelryOrder order) { var s new SaleSummary { TotalSales order.SaleAmount, TotalProfit order.Profit }; switch (order.Category) { case 黄金: s.Gold order.SaleAmount; break; case 钻石: s.Diamond order.SaleAmount; break; case 彩宝: s.Gem order.SaleAmount; break; case 银饰: s.Silver order.SaleAmount; break; } return s; } } } /* # encoding: utf-8 # 版权所有 2026 ©涂聚文有限公司™ ® # 许可信息查看言語成了邀功盡責的功臣還需要行爲每日來值班嗎 # 描述Divide and Conquer Algorithm # Author : geovindu,Geovin Du 涂聚文. # IDE : vs2026 c# .net 10 # os : windows 10 # database : mysql 9.0 sql server 2019, postgreSQL 17.0 Oracle 21c Neo4j # Datetime : 2026/07/05 22:16 # User : geovindu # Product : Visual Studio 2026 # Project : CSharpAlgorithms # File : Role.cs */ using System; using System.Collections.Generic; using System.Text; namespace CSharpAlgorithms.DivideConquer.Entity { /// summary /// 权限二叉树节点 /// /summary public class JewelryRoleNode { public string RoleName { get; set; } public Liststring Permissions { get; set; } new(); public JewelryRoleNode?
