This was really useful in determining one's location during the times when technology wasn't that advanced yet. First is that it depends as to what time of the day is it being used. If used at day, most probably at high noon, the altitude of the sun would be measured and recorded and/or remembered. Most of the times, the latitude is determined during the day since it is much easier. At night, a star of known declination will be substituted to the sun. Most of the times, the North Star is used. Then, an almanac will be utilized to determine the declination of the Sun or the star, depending on which was used. After which, the formula is applied, which is latitude = 90 degrees - measured altitude +declination.
Answer is given below
Explanation:
differences between a file-processing system and a database management system is given below
file-processing system
- File system is a software that manages and organizes the files in a storage medium within a computer.
- It doesn’t provide backup and recovery of data if it is lost.
- There is less data consistency in file system.
- File systems provide less security in comparison to DBMS.
- It is less complex as compared to DBMS.
database management system
- DBMS is a software for managing the database
- It provides backup and recovery of data even if it is lost.
- DBMS has more security mechanisms as compared to file system
- It has more complexity in handling as compared to file system.
- There is more data consistency because of the process of normalization.
