SOLID Design Principles with Designs and Coding Examples

Saba Hussain September 19, 2019 Programming , 0 Comments

S = Single Responsibility Principle
O = Open Close Principle
L = Liskov Substitution Principle
I = Interface Segregation Principle
D = Dependency inversion Principle

SINGLE RESPONSIBILITY PRINCIPLE (SRP) :

The single responsibility principle (SRP) states that every class or module in a program should have responsibility for just a single piece of that program's functionality.

Example:

BAD DESIGN :

BAD CODE:

GOOD DESIGN :

GOOD CODE :

OPEN CLOSE PRINCIPLE (OCP):

In object-oriented programming, the open/closed principle states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; that is, such an entity can allow its behavior to be extended without modifying its source code.

BAD DESIGN :

BAD CODE :

GOOD DESIGN:

GOOD CODE:

LISKOV SUBSTITUTION PRINCIPLE (LSP):

The Liskov Substitution Principle (LSP) functions that use pointers to base classes must be able to use objects of derived classes without knowing it. The Liskov Substitution Principle is a way of ensuring that inheritance is used correctly.

BAD DESIGN:

BAD CODE:

GOOD DESIGN:

GOOD CODE:

INTERFACE SEGREGATION PRINCIPLE(ISP):

Interface segregation principle. In the field of software engineering, the interface-segregation principle (ISP) states that no client should be forced to depend on methods it does not use.

BAD DESIGN:

BAD CODE:

GOOD DESIGN:

GOOD CODE:

DEPENDENCY INVERSION PRINCIPLE(DIP):

The general idea of this principle is as simple as it is important: High-level modules, which provide complex logic, should be easily reusable and unaffected by changes in low-level modules, which provide utility features. To achieve that, you need to introduce an abstraction that decouples the high-level and low-level modules from each other.

Fibonacci Series is a series of numbers where the first two Fibonacci numbers are 0 and 1, and each subsequent number is the sum of the previous two.

For Example:

and so on ...

JavaScript Code:

In JavaScript, Variable declaration is done by using var keyword, followed by variable name.
In JavaScript, document.write is the output statement.
In JavaScript, prompt is used to get the input from the user.
In JavaScript, function FuncName() { } is used for creating a function.

File Organization in Database [SQL Server]

Saba Hussain February 03, 2019 Logic , Programming 7 Comments

File Organization In Database[COMPLETE CONCEPT]

FILE ORGANIZATION:

Storage and access method of a file is called file organization.

TYPES OF FILE ORGANIZATION:

1.Sequential File Organization

2.Direct access File Organization

SEQUENTIAL FILE ORGANIZATION:

When we have to access data in sequence.

Example:

Tape-drive. In tape drive if we want to access the 2nd video we have to go through the 1st then we can access the second one . We can’t jump directly to 2nd .

ADVANTAGE OF SEQUENTIAL FILE ORGANIZATION:

Sequential saves memory. Because there is no meta data (header/footer) with a single record.

USES OF SEQUENTIAL FILE ORGANIZATION:

Sequential file organization is helpful when we have to access the whole batch . i.e Electricity bills.

DRAWBACKS OF SEQUENTIAL FILE ORGANIZATION:

1.Time loss

2.Searching is difficult in Sequential file Organization

3.If we try to insert a new data we have to reorganize the whole data.

4.If we are searching a data which is not present in the records. It will search the whole data then tell that the data is not present.

DIRECT FILE ORGANIZATION:

Example:

Hard Drive.

ADVANTAGES OF DIRECT FILE ORGANIZATION:

1.Time saving

2.Searching is easy in Direct file Organization

TYPES OF DIRECT FILE ORGANIZATION:

1.Indexed Sequential

2.Hashing

INDEXED SEQUENTIAL:

Indexed Sequential is same as Table of Content in books.

HASHING:

Hashing is a function but not a specific function. We can made our hashing function.

TYPES OF HASHING FUNCTION:

1.Division method

2.Folding method

DIVISION FUNCTION:

x mod y return remainder. If remainder of two numbers are same then it is called hashing conflict.

SOLUTION OF HASHING CONFLICT:

Add 1 to the remainder.

FOLDING METHOD:

You can fold a number to find that in which track the given record should go.

FOR EXAMPLE:

Suppose a record with Student ID 8530 & you have to use folding method to tell that which hard drive’s track will hold this record ?

8 5 3 0

8 5

+ 3 0

--------------

11 5 <------- This record will save in 5th
---------------
track in hard drive!

THANK YOU... 🙂
