Problems of a traditional environment
- Traditional file management techniques make it difficult for organizations to keep track of all of the pieces of data they use in a systematic way and to organize these data so that they can be easily accessed.
- Different functional areas and groups were allowed to develop their own files independently.
- The five main problems of a traditional file environment include:
- Data redundancy and inconsistency
- Program-data dependence
- Inflexibility
- Poor security
- Lack of data sharing and availability...

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.
