What Is Database Normalization?

Database construction is the key to system construction. When building a database, we must fully consider the need for effective data sharing, and also ensure the legality and security of data access. The database uses a unified coordinate system and elevation datum. The vector data uses geodetic coordinates. The geodetic coordinates are numerically continuous. This avoids the problem of cross-band Gaussian projection, thereby ensuring the integrity of the geographic objects of the database. to offer comfort. ^[1]
