Database relationship

Database relationship

Microsoft Access is an example of relational database. In relational data base we can join a table to more than one table which makes relationship. With this capability our access database becomes more powerful than non-relational data base category. Consistency of database become easy and easily achieve by database on automatically.  If you want to make relationship in access database then you need at least two tables and one field must be common in both tables. For example, we are going to make relationship between two tables’ student and canteen. Student table store record of student and canteen stores what the products students are having. So in this type of relationship student is master table and canteen is related table. So student table need a primary key which uniquely identified a record from student table. Canteen table must have a key which match the data type of student table primary key which further known as foreign key.

The following is a partial taxonomy of rotating electrical machines. Electrical machines may
be categorized for analysis purposes into alternating current (ac) or direct current (dc).
Some machines run on ac, some on dc, and some will run on either. An ac machine may
be synchronous or induction. A few examples of electrical machines include large
synchronous motors, small induction motors, universal motors, and permanent magnet
motors. Most motors found in the homes are usually induction machines or universal
motors. Universal motors are typically used in where high speed is needed such as in
blenders or vacuum cleaners. They will run on either “AC” or “DC”. Permanent magnet
motors are frequently used in toys and will work only on dc.

Polymorphism

Polymorphism Banner


“One name many form.”

Polymorphism gives the ability to dynamic programming to a language which reduces to write repeated code for each module. You can use polymorphism for flexible programming for example if you‘re making software for a school and you need to print record of different type person which may be student, teacher, non teaching staff etc. So without using polymorphism you need to make separate function for each person related record printing. which lead to increase complexity. In polymorphism you need to make a function for printing record and rewrite different version of this as printing which are isolated by function signature. So you have a better approach to solve your need with flexible coding.
