Описание: Learn SQL (Structured Query Language) from Installation to Database Management and Database Administration
Anything that stores data records is called a database. It can be a file, CD, hard disk, or any number of storage solutions. From a programming point of view, a database is a methodically structured repository of indexed data information that can be easily accessed by the users for creating, retrieving, updating and deleting information.
Data can be stored in many forms. Most applications require a database for storing information. A database can be of two types:
(1) flat database and (2) relational database.
As the name suggests a flat database has a two-dimensional structure that has data fields and records stored in one large table. It is not capable of storing complex information, which creates a need for relational databases. A relational database stores data in several tables that are related to each other.
Let's take the example of a school.
A school will have to maintain data for several students. To find information for a student, we will first ask the class name. After the class name, we will ask for the first name. However, if there are two children with the same first name, then we will ask for the surname.
If there are two children will identical names, we can still discriminate the information related to them based on their student id, parents' name, date of birth, siblings in the same school, etc.
This is all related information. When all of this information is stored on paper, it takes a lot of time to retrieve it. The relational database allows easy access to all of this information.
SQL is a computer language we can use to work with the various database management systems. It is the standard language for the various relational database management systems such as Oracle, MySQL, MS Access, SQL Server, Postgres, Sybase, etc. With the use of SQL, a database user can create various database objects and perform various manipulations on them.
When they have accomplished the tasks, they were using the objects for, the users can drop these database objects. A good example of a database object is a table which is a combination of rows and columns. Tables allow us to group our data into rows and columns.
SQL allows you to create a table, insert data into it, manipulate this data and even drop it when you are done with its use.
Besides this, SQL allows you to impose constraints on the table to restrict the data that can be inserted into that table. You must have data you need to store well. The data should be safeguarded against loss. If the data is sensitive, you need to safeguard it so it doesn't land into the wrong hands.
You also need a way of organizing this data so it becomes easy for you to retrieve it. You only need to get a database management system and SQL will help you achieve all of this.
This book is an excellent guide for you to learn SQL. It explores everything about this computer database language.
Описание: Would You like To Master The Linux Operating System but you don't know where to start?
Linux is an operating system, which is pretty much different from any other one.
Linux is a free and open-source Operating System, based on UNIX and PSOIX codes. In short, it is free to download, and free to use, and was originally based on the paradigm of Intel x86.
Linux gets to be tailored to any system where it's being used for-compared to other operating systems that work best on a certain kind of device alone.
Open-source so happens because of the so-called open-source software collaboration that can support various kinds of libraries and directories.
Advantages of Using Linux:
Free to use.

In the early 1980s, Python was designed. Initially, Python did not make its mark in the industry as intended due to the absence of adequate marketing. It also had some inbuilt problems relating to the key idea, which worked as an obstacle in its successful route.
With renovation by Google within the twentieth century, improvements were seen in Python, as some needed modifications where made in its set-up and settings.
As a consequence, it has acquired the authority and efficiency within itself. Google altered the language's key logic and also removed all of the library's repeated modules and techniques to make it smoother and lighter.
Its efficiency has now improved more than three times than before. It, therefore, becomes one of the industry's most powerful languages, gaining tremendous popularity among developers and tech experts over the past decade, turning out to be a gem in the IT industry.
Today, many programming languages exist. Some are being used, and some are now deemed outdated. The programming situation has altered dramatically over the past few years as designers and programmers are looking for more universal and accessible languages, and this is why the language of Python has lately become so popular.
The Python community is increasing day by day, as many programmers find it one of the most user-friendly programming languages.
Python's development today involves different individuals with a broad spectrum of backgrounds, ages, and instructional levels - whether you're a student, a computer designer, a housewife, or a retiree, you can be a part of the process.
There are always some thorough guidelines to make your introduction to the subject easier and more sustainable to ensure your success. Much guidance can be found on the Internet.
If you are starting with programming and have no knowledge about computers and programming, this book is written for you.
You will find initial chapters easier to understand and as you progress to later chapters, you will have better skills and we will cover more advanced topics.
This book is written in one flow and it's better not to skip any topic, let alone an entire chapter.
This book gives a comprehensive guide on the following:
The basic background of python
Data types in python
Operators - the types and their uses
Loops and functions
Exception handling
Variable scope and lifetime in python functions
Modules
Working with files
Object-oriented programming
Real-world examples of python
Getting started; python tips and tricks
Common programming challenges
... AND MORE
However, you can get to know some starting points and steps once you purchase this book.
