Question:
- The hospital currently has 1,250,000 patients in a legacy system which has been running for the past 10 years. These will be transferred to the new system.
- It is estimated that 250,000 new patients will be added each year and 100,000 existing patients will return for a visit every year. For those patients in the legacy system, the average number of visits over 10 years is 6.
- The new system includes the following data.
- Patient identification (300 bytes)
- Visit information (450 bytes per visit)
- Diagnosis information (600 bytes per diagnosis), average number of diagnosis is 3
- Lab results (800 bytes per lab), average number of labs per visit is 3
- Image results (20,000 bytes per image), average number of images per visit is 2
- Physician notes (1,500 bytes per contact), average number of contacts per visit is 6
- Allow 45% overhead for the database management system (including additional files for indexing, metadata, etc.)
- A full backup will be taken daily and each backup will be kept for 10 days.
- A daily transaction log will be maintained for 5 days; it is estimated that there are some 25,000 transactions per day (average size is 500 bytes)
- Develop a detailed spreadsheet showing your calculations on disk capacity requirements:
- When system installed
- At 1 year
- At 10 years
Note: the project manager says these numbers may change so make a spreadsheet that allows you to easily change the numbers
