- All computers are the same they use the same basic logic, storage etc.
- Always make backups. Storage is cheap...so better to save too much than too little.
- Many times the problem/solution is simple...don't over think it, but thought is good.
- When accessing files/records without a sort (natural) they display as stored on disk. Usually by time at first, but becomes mixed as old files/records are deleted and new files/records are added.
- Remember that everything is ones and zeros to a computer. So, letters and other data types are still just numbers.
- Always do a select before a delete with everything...file system, database, application, etc.
- When working with databases always rename objects before dropping...
- Remember a little change can have large effects!
- Always separate the OS from data on the hard drive.
