企业数据采集系统上线后迭代：新增数据源 / 调整采集频率 / 优化数据质量方法

// 数据采集接口标准定义
public interface IDataSourceConnector
{
    Task ConnectAsync(ConnectionConfig config);
    Task StartCollectionAsync(CollectionParameters parameters);
    Task DisconnectAsync();
}

// 新数据源实现示例
public class NewApiDataSource : IDataSourceConnector
{
    public async Task ConnectAsync(ConnectionConfig config)
    {
        // 实现API数据源连接逻辑
        // 包含认证、授权和连接测试
        return await ConnectToApiAsync(config);
    }
    
    // 其他接口实现...
}

// 基于数据变化率的频率调整算法
class AdaptiveCollectionScheduler {
  constructor(baseFrequency = 3600000) {
    this.baseFrequency = baseFrequency; // 默认1小时
    this.changeThreshold = 0.1; // 变化率阈值
  }
  
  // 计算下一次采集时间
  calculateNextCollection(lastData, currentData) {
    const changeRate = this.calculateChangeRate(lastData, currentData);
    
    if (changeRate > this.changeThreshold) {
      // 数据变化大，增加采集频率
      return this.baseFrequency / 2;
    } else if (changeRate < (this.changeThreshold / 5)) {
      // 数据变化小，降低采集频率
      return this.baseFrequency * 2;
    }
    
    return this.baseFrequency;
  }
  
  calculateChangeRate(previous, current) {
    // 实现数据变化率计算逻辑
    return Math.abs(current - previous) / previous;
  }
}

// 数据质量校验服务示例
public class DataQualityService
{
    private readonly List _validators;
    
    public DataQualityService()
    {
        _validators = new List
        {
            new CompletenessValidator(),
            new FormatValidator(),
            new ConsistencyValidator()
        };
    }
    
    public async Task ValidateAsync(RawDataRecord data)
    {
        var result = new ValidationResult();
        
        foreach (var validator in _validators)
        {
            var validationResult = await validator.ValidateAsync(data);
            result.Merge(validationResult);
        }
        
        return result;
    }
}

// 数据清洗处理器
public class DataCleaningProcessor
{
    public ProcessedData CleanseData(RawDataRecord rawData)
    {
        // 实现数据清洗逻辑：去重、格式化、标准化等
        return ApplyCleaningRules(rawData);
    }
}
