Smalltalk 语言体育数据系统：运动员成绩管理工具的实现

Smalltalk 是一种面向对象的编程语言，以其简洁、直观和强大的对象模型而闻名。在体育数据系统中，运动员成绩管理是一个关键的功能，它涉及到数据的收集、存储、分析和展示。本文将探讨如何使用 Smalltalk 语言实现一个运动员成绩管理工具，包括系统的设计、关键功能的实现以及性能优化。

系统设计

系统架构

运动员成绩管理系统采用分层架构，主要包括以下几层：

1. 数据层：负责数据的存储和检索。
2. 业务逻辑层：处理业务规则和数据处理。
3. 表示层：负责用户界面的展示。

数据模型

在 Smalltalk 中，我们可以使用类来定义数据模型。以下是一个简单的运动员成绩数据模型：

smalltalk
| athleteId name scoreList |

Class category: 'Athlete' instanceVariableNames: 'athleteId name scoreList' classVariableNames: '' poolDictionaries: '' category: 'Model' methodsFor: 'initialization' put: 'initialize' into: 'classMethods'.
initialize
^ self basicNew
end

Class category: 'Athlete' instanceVariableNames: 'athleteId name scoreList' classVariableNames: '' poolDictionaries: '' category: 'Model' methodsFor: 'initialization' put: 'initialize' into: 'classMethods'.
initialize
| athleteId name scoreList |
athleteId := 'A' & (1 to: 1000) do: [ :i | i asString ].
name := 'Athlete ' & athleteId.
scoreList := List new.
^ self basicNew
end

Class category: 'Athlete' instanceVariableNames: 'athleteId name scoreList' classVariableNames: '' poolDictionaries: '' category: 'Model' methodsFor: 'initialization' put: 'initialize' into: 'classMethods'.
initialize
| athleteId name scoreList |
athleteId := 'A' & (1 to: 1000) do: [ :i | i asString ].
name := 'Athlete ' & athleteId.
scoreList := List new.
^ self basicNew
end

业务逻辑层

业务逻辑层负责处理运动员成绩的添加、删除、更新和查询等操作。以下是一个简单的业务逻辑类实现：

```smalltalk
Class category: 'AthleteScoreManager' instanceVariableNames: 'athleteScores' classVariableNames: '' poolDictionaries: '' category: 'Manager' methodsFor: 'initialization' put: 'initialize' into: 'classMethods'.
initialize
^ self basicNew
end

Class category: 'AthleteScoreManager' instanceVariableNames: 'athleteScores' classVariableNames: '' poolDictionaries: '' category: 'Manager' methodsFor: 'initialization' put: 'initialize' into: 'classMethods'.
initialize
^ self basicNew
end

Class category: 'AthleteScoreManager' instanceVariableNames: 'athleteScores' classVariableNames: '' poolDictionaries: '' category: 'Manager' methodsFor: 'initialization' put: 'initialize' into: 'classMethods'.
initialize
