Explain Basic Structure of DBMS

What is DBMS?

A database management system is software that allows you to store and manipulate various operations in a database. A DBMS provides users and programmers with a systematic way to create, retrieve, update, and manage data. DBMS are actually tools used to perform all sorts of operations on the data in the database.

Structure of DBMS as below

Query Processor: It is used to translate requests that are directly coming from end users via application programs into instructions.

Query Processor contains the following components  

DML Compiler: DML Compiler processes DML instructions into low-level instructions i.e (machine language) so that they can be executed.

DDL Interpreter: Processes DDL statements in a set of tables containing metadata (data about data).

Embedded DML Precompiler: Process embedded DML statements in your application program into procedure calls.

Query Optimizer: Executes statements generated with the aid of using the DML compiler.

Storage Manager: A storage manager is a set of instructions that works as an interface between the database and incoming queries sometimes also known as a database control system. Database consistency and integrity are maintained by enforcing constraints and executing DCL statements. Responsible for updating, storing, deleting, and retrieving data in the database.

Disk Storage: It contains the following components –

Data Files: It is used to store the data in data files.

Data Dictionary: It contains the information about the structure of your database object which represents the repository of information with the metadata.

Indices: It is used to process faster loading of data items from the database.

DBMS contains following topics at TCCI:

Part-I: Database

Data Types in SQL with Examples

SQL (Structured Query Language) is everywhere, and in today’s digitalized world with massive amounts of data being gathered every day and stored into a database, knowing how to program with SQL is imperative. Whether you’re a marketer or an aspiring developer, SQL is a great language to learn.

String Data Type

CHAR – Char type is used to store a fixed length string that can contain alphanumeric include numbers, letters, and special characters etc.

VARCHAR – Varchar type is used to store only string variable with fixed length alphanumeric characters that can contain numbers, letters, and special characters.

BINARY – Binary type is equal to CHAR type but stores only binary byte data strings.

TEXT –            Text type is store a string that can contain a maximum length of 255 characters.

ENUM -Enum type used only when a string contain only one value, where you have to select from a list of possible values.

BLOB – Blob type is used to store only for BLOBs type data value i.e. (Binary Large Objects).

Numeric Data Type

INT – INT type is used to store integer value.

FLOAT – Float type is used to store a floating point number.

DOUBLE – Float type is used to store a double point number.

DECIMAL – Decimal type is used to store a decimal point number.

BOOL – Bool type used to store only specify Boolean number values either true and false.

Date and Time Data Type

DATE -Date type is used to store only specify date format type in this format YYYY-MM-DD.

TIMESTAMP – TIMESTAMP type is used to store the timestamp data with the format of hour-minute-seconds.

YEAR – Year type is used to store data in a year format i.e. four-digit format.

Why HTML-CSS-JavaScript required for Web Development?

You must learn HTML-CSS-JavaScript for web development because most of the web pages and website are developed in HTML. HTML- Hypertext Mark-up Language is standard mark-up language which is very useful in creating webpage and web application. HTML describes the structure of Web pages using mark-up. HTML elements are the building blocks of HTML pages. HTML elements are represented by tags.

CSS is highly useful in web development as we know CSS is a language used to detail the presentation of a web page’s mark up language such as colors, fonts, and layout. CSS are an important way to control how your Web pages look. It controls colors, typography, and the size and placement of elements and images. CSS Conserves user bandwidth, Speeds up page rendering, Reduces design and development time, Reduces updating and maintenance time  Design-wise it is easier, clearer, flexible, and more resilient if these “concerns” are kept separate from one another. 

JavaScript is useful in web development as an object-based scripting language that is lightweight and cross-platform. JavaScript is not compiled but translated. The JavaScript Translator (embedded in browser) is responsible to translate the JavaScript code.  it useful for validating input in a web browser without needing to go to the server. It useful for manipulating HTML DOM, CSS when user is interacting with a webpage.

C Computer Course Training in Ahmedabad

C is a high level language and structured programming language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs.

C coding language features were derived from an earlier language called “B” (Basic Combined Programming Language – BCPL).

C is very popular because of Reliability, Portability, Flexibility, Interactivity, and Modularity.

C is a middle level programming language. Main feature of C is we can divide programme into the smaller modules which increases efficiency of programme.

C contains following topics at TCCI:

Advantages of Learning Java Programing Language

Java language class-based and object-oriented is designed so that any program can be quickly executed with minimum dependencies. As we know Java technology is used to develop highly advanced applications for a variety of domains, from consumer devices to enterprise systems with singleton architecture. This section provides an overview of the Java platform and its components.

A program can runs as a separate computer process without adding to an existing file process is called a that’s why it’s called a standalone application. Also, no operating system processes are required. Create a standalone application using AWT (Abstract Window Toolkit) and Swing.

A Java web application is a client-server based software application that is run by a client include email, online retail sales, and Wikipedia information. Servlets, jsp, jsf used to build web applications.

Java applications are enterprise applications related to middleware applications. All companies use Java technology and services to enable their software applications and hardware systems. Therefore, we call it an enterprise application. Enterprise applications are designed primarily for enterprise sites such as banking systems.

Java Programming Language contains following topics at TCCI:

Explain Basic Structure of Python Programing

The structure of Python language is depends on its flexibility, simple syntax easy to read and understand without any programming knowledge. As we know Python is a programming language with multiple paradigms: object-oriented programming and structured programming.

Python is one of the most popular programming languages ​​today and a fundamental step to get started in the world of programming and frameworks. Python programming is easy to learn and doesn’t require much effort. From an industry perspective, Python is one of the most popular programming languages ​​today.

In Python, numeric data types are used to represent data numerically. When declaring data types in Python, numbers can be integers, floats, and even complex numbers. In Python, string data types are sequences of Unicode characters.

A string is usually a collection of one, two, or more characters enclosed in double, double, or triple quotes, depending on the data type of the list. In Python, the tuple data type is defined as an ordered collection of Python objects.

The main difference between tuples and lists is that tuples are immutable. Tuples cannot be modified after creation. The Tuple class represents that. In Python, parentheses () can be used to represent tuples. Python programming is currently in high demand among those interested in this field and wanting to pursue a career.

In 1983, “C with Classes” was renamed to “C++”, adding new features that included virtual functions, function name and operator overloading, references, constants, type-safe free-store memory allocation (new/delete), improved type checking, So, We can say that c++ is an extension of C language.

C++ contains following topics at TCCI:

Introduction to C++, Basic Syntax, Object Oriented Concept, Data Types and Variables, Constants, Literals, Modifiers, Operators, Loop Controls, Decision Making, Class Structure with Object, Function, Arrays, String, Inheritance, Constructor-Destructor, Exception Handling, Files etc…..
