Tool and techniques of a school data base Relationship: This is the connection of the teacher with it subject and the student to the subject Record: a record is a group of fields within a table that are relevant to a specific entity. For example, in a table called student contact information, a row would likely contain fields such as: ID number, name, street address, city, telephone number etc. Field characteristic: It is used for more general text as opposed to specific information. A name or address would be in a text field, but something like school it talk most about the student Sorts and queries: A database queries is use to search for information on the database while the sorts is the arrangement of the information maybe in ascending or descending order. Form: database form is where the school encodes the data to be stored.

How could the tools/techniques improve a database Productivity: this help to improve the database by making the database function Accuracy: Accurate databases rely on good input. if the data isn't accurate, it then becomes subject to errors and it's usefulness becomes increasingly less. If I have a database of prices and half are wrong, the database will eventually cause the business to lose money or overcharge. Usability; this is use full for the database because it make it easy to access the database Productivity: this help to improve the database by making the database function Accuracy: Accurate databases rely on good input. if the data isn't accurate, it then becomes subject to errors and it's usefulness becomes increasingly less.
