What is Presto or Presto DB?

It(Presto) written in the language Java and formulated on 10 November in the year 2013 by Facebook. It is also known as PrestoDB and it helps non-relational data sources and relational data sources. Non-relational data sources are like MongoDB, Base, Amazon S3, HDFS (Hadoop Distributed File System) and relational data sources are Microsoft SQL Server, MySQL, PostgreSQL and Teradata. It’s(Presto) an open-source SQL query engine that is created for a large scale industry that circulated for several servers and for running fast.

Many companies are using this like Facebook, Netflix and some trending network companies are Dropbox, Airbnb, Groupon. It(Presto) is formulated to solve the query immediately and a data infrastructure group of Facebook created this. Several organizations and Facebook allotted for this , while it’s(Presto) become trending for doing interactive queries on Hadoop.

By utilizing Presto per day Facebook solves at least 30, 000 queries. Many data driven companies use this and for them it(Presto) has become a choice. On your data you can easily operate this SQL queries.

It facilitates data where it dwells, which means data that has the query consists of Hadoop, relational databases, Cassandra, NoSQL databases, AWS S3. It also permits the users to access the data from several sources that permit the whole organization for analytics.

Presto as per Wikipedia:

It(including PrestoDB, and PrestoSQL which was re-branded to Trino) is a distributed query engine for big data using the SQL query language. Its architecture allows users to query data sources such as Hadoop, Cassandra, Kafka, AWSS3, Alluxio, MySQL, MongoDB and Teradata, and allows use of multiple data sources within a query. this is community-driven open-source software released under the Apache License.

Features of Presto

There are some important features of Presto which we are discuss in broadly in points as mentioned below:

All the data sources have been authorized: This feature is very unique and makes presto distinct from other data sources platforms. Presto attaches the data from other sources because it does not have its own storage but it reads the data from them. By Presto, you can utilize numerous data sources at one time and from these multiple data, only one query can cross the source data.

It has the highest speed: Having big data forms a big list of queries such as a user-facing data-driven application. Presto permits to build this without having an intermediary system needing the performance.
By using Presto, your business empower with real-time analytics as well it explore and visualize your data in time, regardless of its size or complexity.

Obtainability is high: If you want to change you can change the worker according to your wish or want or even you can add them also. It (Presto)also provide the high performance as Presto is known for its exceptional query performance. It(Presto) achieves this through techniques like in-memory processing, vectorized execution and pipelining. These optimization minimize data movement and processing overhead, resulting in faster query response times.

Pipelined In-Memory Execution: In presto, there are no other results kept in the disk and it accomplishes the whole processing in memory.

Open Sources: Presto is an open-source project that is maintained by the Presto Software Foundation. The open nature of Presto encourages in fosters innovation, community contribution, and ensure transparency in its development.

Advantage of Presto

One of the important advantage of Presto are as follow:
Anyone can understand this, because it is simple to use and easy to understand.
It operates many queries, it solves over 30,000 queries per day on Facebook, as well on many other network sites.
It is unique and what make it different is because it support ANSI SQL.
It support a large amount of data in very high speed.

Conclusion: Presto DB is formulated to solve the query immediately and a data infrastructure group of Facebook created this. In the conclusion we only conclude that this is a simple language that any one can understand this Presto and can support the large amount of data in very high speed.

What Is Programming Language?

As we have already mentioned and explained programming languages in our previous blog, let’s now delve into their types. There are many different types and categories of programming languages: Procedural, Functional, Object-Oriented, Scripting, Logic etc.

A programming language is a way for the Developers or Programmer to communicate with computers and other devices(IOT) using machine understandable code.

There are many programming language available across the world, each language is created for specific features and when the language is written it is required to be translated into bytecode and machine code which the computer can then perform.

Different Types Of Programming Language

Now let us look at the different ways these programming languages can be grouped and categorised. There was many ways we can grow these languages based on their behaviour, execution style, structure and many other parameters. The diagram below shows some the common ways to define and group the programming languages as Procedural, Functional,Logic based, OOPs, Scripting etc to name a few.

Procedural Programming Languages

A computer programming languages that is formulated for writing programs and it concentrate on explaining the process that a program need to gain some target. It is best for those tasks where a big problem has to divided into smaller and find a simpler way to get the solutions. In the other word, a programming model that is based upon the concept of procedure, that means routines, functions and includes some computational steps.

PL/C
PL/I
MATLAB
HyperTalk
Go
Ada
Fortran

Functional Programming Languages

Functional programming languages is based on mathematical functions and avoid movable data. It utilized it’s functions as a primary building blocks of programs. Here you cannot change the data structure which is created and it is formulated when modifications are required. It has other important features that is pure function that means provide same input as same output. Some common examples of Functional programming languages are

ML
Erlang
Haskell
F#
Scala

Object-oriented Programming Languages

The concepts of OOPs are Classes, Object, Polymorphism, Abstraction, Inheritance & Encapsulation. This language is based on the principle of object-oriented programming. This language is totally depends upon object –oriented program and circulated around the concept of object. With the help of this language developer construct and formulate software that can charge to more organized and maintainable code. Examples of OOPs languages are:

Java
Python
PHP
C++
Ruby

Scripting Languages

This language is constructed to utilized for easy and quick writing scripts that help in automation of tasks, exploit data and have to perform several functions. This is a simple language that anyone can use and utilized to automate the tasks manipulate the data. Some famour scripting languages are : Python, and Bash etc. these languages make the important tools in automation and programming.

Bash
JavaScript
Lua
Tcl
VBScript
Windows PowerShell
F-Script
BeanShell

Markup Languages

A markup language can be defined as an artificial language that used for annotating a document so that it is syntactically distinguishable from the text, the text that define how the text is to be displayed.
Examples:

HTML
XML
XHTML
SGML
Curl

Logic Programming Languages

It is based on the principle of formal logic and these languages is beneficial to solves the query in symbolic reasoning, knowledge representations etc. It is focus on what we have to gain rather how we can and it also consists of inference mechanism that permit the system to reduce latest logic from the rules and facts. Some of the logic programming languages include:

Prolog
Absys
Datalog
Alma-0
Fril
Janus

Machine languages

These languages are directly executable by a compute Central Processing Unit. Machine languages are typically coded in bit patterns, represented in octal or hexadecimal forms.
Examples:

ARM
DEC
x86
IBM System/360
MIPS
Sun, Oracle SPARC

Visual languages

In Visual Languages users can specify programs in a 2-D or more way instead one-dimensional (text strings) in visual languages we use graphical elements and figures to develop a program. Some common example of Visual languages include:

Analytica
Blockly
DRAKON
Fabrik
Scratch
Simulink
Spreadsheets

Concurrent Languages

These languages are constructed for concurrency in Message passing languages. For example, Java shows shared-memory concurrency.
Examples of Concurrent languages:

Go
Java
Julia
clojure
Scala

Difference Between Front End & Back End Languages

S.NO.	Front End	Back End
01	It makes a user reflecting part of website or application.	It develops a server side of a application or website.
02	Angular, React are the frameworks of front end	Ruby, Flask & Django are the frameworks of back end.
03	It is responsible for constructing the layout of application and website.	It create and maintaining APIs, servers and the important database.
04	Frontend is a part of website, users can interact with it.	Backend means regulate everything behind the scenes.
05	It include HTML, JavaScript etc.	It include Python, Ruby, Java etc.

Difference Between High Level & Low Level Language

S.NO.	High Level	Low Level
01	There is no requirement of hardware knowledge	Hardware knowledge is required
02	A simple and easy language to learn.	Not an easy language.
03	It is portable	It is totally depend on machines and not portable.
04	Python , Java are the example of high level	Machines code and assembly are the example of low level.
05	It has the large community.	It has lower community support

Conclusion

As we know, there are approximately 700+ programming languages, and these languages are categorised into different types and categories like, object-oriented programming languages, scripting languages, markup languages etc.

Programming languages are crucial for all developers and programmers to interact and communicate with computers through code, no matter how simple it may be.

Through this post we have tried to share out thoughts on different ways the known programming languages can be classified based on there syntax, interpretation, behaviour etc.
