"Mastering SQL Table Joins from scratch: Real World Examples"

"SQL is a special-purpose programming language designed for managing information in a relational database management system (RDBMS). The word relational here is key; it specifies that the database management system is organised in such a way that there are clear relations defined between different sets of data. Join makes relational database systems relational.Joins allow you to link data from two or more tables together into a single query result--from one single SELECT statement..When combining rows from multiple tables in one query, you need to use the JOIN command. There are a few different types of joins, and the following should help explain the differences between them.The syntax will vary depending on which database type you are using. In this course i have used Oracle database.The JOIN operations, which are among the possible Table Expressions in a FROM clause, perform joins between two tables.Below is a brief description of the various types of joins used in Oracle.INNER JOIN operationSpecifies a join between two tables with an explicit join clause.LEFT OUTER JOIN operationSpecifies a join between two tables with an explicit join clause, preserving unmatched rows from the first table.RIGHT OUTER JOIN operationSpecifies a join between two tables with an explicit join clause, preserving unmatched rows from the second table.CROSS JOIN operationSpecifies a join that produces the Cartesian product of two tables. It has no explicit join clause.NATURAL JOIN operationSpecifies an inner or outer join between two tables. It has no explicit join clause. Instead, one is created implicitly using the common columns from the two tables.In all cases, you can specify additional restrictions on one or both of the tables being joined in outer join clauses or in the WHERE clause.In this course there will be lots of hands-on real world examples of SQL table joins."

"Data Migration: Database Migration MS SQL to Oracle DB"

"Data Migration is an important function anyone working with a database should be able to carry out.There are several tools available to perform database and data migration. In this course we will be using a free powerful tool by Oracle called Oracle SQL Developer to migrate a third party database from Microsoft SQL Server into Oracle.Database migration involves several steps specified below:Setting up a Migration Repository : The Migrations Repository is a database schema that stores themeta_data collected and transformed in the migration process.Configuring the Third Party Database Connection : You need to configure a database connection for the databasewhich you would like to migrate. There are two steps to this process:Download JDBC driver and Connecting to ThirdParty Database.Capturing Source Database :This step is used to capture a snapshot of the current stateof your third-party database and is necessary to provide SQL Developer with a ""point in time"" view of your database. Once this step is complete, the Migration wizard works on the meta-data stored in its repository, instead of issuing queries against your live database.Convert Captured Model to Oracle : The next step in the migration process is to convert the captured modelof the database to an Oracle-specific model.Translate Third Party SQL Objects to Oracle :The next step in the migration process is to translate theT-SQL objects - constraints, functions, procedures, triggers, views - to Oracle SQL objects.Generating Scripts to Create Target Database :Once the conversion process has completed, SQL Developer hasa model of what the converted database will look like. This is used to generate SQL scripts for the creation of the new Oracle Database schema(s) and to run these scripts.Move Data from Third Party Database to Oracle :The last step in the Migration Wizard is to move the data to the new database. Migrating the data is a process that copies the data from the third-party database to the new tablesin the Oracle database. The Migration Wizard uses the same Oracle database connection required to run the scripts as it does to move the data."

"Data Analysis With PostgreSQL: Analytic Aggregate Functions"

"Due to the ever increasing reliance and growth of data there is even a greater demand for professionals who can help analyse these large volume of data that is used daily in applications that we use and rely on daily like Facebook, Instagram,bank apps etc.Aggregate functions perform a calculation on a set of values and return a single value. Analytic functions compute an aggregate value based on a set of values, and, unlike aggregate functions, can return multiple rows for each set of values.If you want to run a query using only aggregate functions, the query will return one row with a column for each field. If you want to run a query using an aggregate function in conjunction with the GROUP BY function, the query will return one row for each value found in the grouped field.If you want to run a query using an analytic function, the query will return one row for each field in the defined range of fields used to perform the calculations.If you use an aggregate function with any other function in a query, one field in the query must contain the GROUP BY function.Analytic functions are frequently used in fields such as finance and science to provide trend, outlier, and bucketed analysis for large data setsUnlike traditional aggregation functions, which return only a single value for each group defined in the query, Analytic functions return a single value for each input row .They increase the efficiency and reduce the complexity of queries that analyse partitions (windows) of a data set.This course will use aggregate and analytic functions to query and analyse data from a PostgreSQL database."

"Using SQL for Data Science"

"The role of a data scientist is to turn raw data into actionable insights. Much of the world's raw datafrom electronic medical records to customer e-commerce transaction historieslives in organized collections of tables called relational databases. Therefore, to be an effective data scientist, you must know how to wrangle and extract data from these databases using a language called SQL (pronounced ess-que-ell, or sequel).As data collection has increased exponentially, so has the need for people skilled at using and interacting with data; to be able to think critically, and provide insights to make better decisions and optimise their businesses. This is where the data scientist comes in. According to Glassdoor, being a data scientist is the best job in America; with a median base salary of $110,000 and thousands of job openings at a time. The skills necessary to be a good data scientist include being able to retrieve and work with data, and to do that you need to be well versed in SQL, the standard language for communicating with database systems.This course is designed to give you a primer in the fundamentals of SQL and working with data so that you can begin analyzing it for data science purposes.

"Joining Data and using Triggers in PostgreSQL"

"The PostgreSQL Joins clause is used to combine records from two or more tables in a database. A JOIN is a means for combining fields from two tables by using values common to each.The main concept which is focusing on a join is that, two or more data sets, when joined, combined their columns into a new set of rows, including each of the columns requested from each of the data sets. All joins are standing on the foundation of Cartesian product. The Cartesian product is the set of all possible combinations between two data sets. A join creates a set of rows in a temporary table and works on two or more tables, and each table should at least one common field and must maintain a relation between the common fields. Join keeps the structure unchanged of the base tables.Types of PostgreSQL JOINCross JoinInner JoinLeft Outer JoinRight Outer JoinFull Outer JoinA PostgreSQL trigger is a function invoked automatically whenever an event associated with a table occurs. An event could be any of the following: INSERT, UPDATE, DELETE or TRUNCATE.A trigger is a special user-defined function that binds to a table. To create a new trigger, you must define a trigger function first, and then bind this trigger function to a table. The difference between a trigger and a user-defined function is that a trigger is automatically invoked when an event occurs.PostgreSQL provides two main types of triggers: row and statement level triggers. The differences between the two are how many times the trigger is invoked and at what time. For example, if you issue an UPDATE statement that affects 20 rows, the row level trigger will be invoked 20 times, while the statement level trigger will be invoked 1 time.You can specify whether the trigger is invoked before or after an event. If the trigger is invoked before an event, it can skip the operation for the current row or even change the row being updated or inserted. In case the trigger is invoked after the event, all changes are available to the trigger.We will create and manage a basic trigger in this course."

Programming can be fun as well as challenging.In this beginners course we will be learning to code using four very popular and high in demand programming languages:JavaPythonJavaScriptC#Java is a general purpose high-level, object-oriented programming language.Java is one of the most commonly used languages for developingand delivering content on the web. An estimated nine millionJava developers use it and more than three billion mobile phones run it.Java is an object-oriented language, which means that programmersdefine not only the data type of a data structure, but also the types of functions that can be applied to the data structure.Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together.JavaScript is a programming language for the web. It is supported by most web browsers including Chrome, Firefox, Safari, internet Explorer, Edge, Opera, etc. Most mobile browsers for smart phones support JavaScript too.C# is an elegant and type-safe object-oriented language that enables developers to build a variety of secure and robust applications that run on the .NET Framework. You can use C# to create Windows client applications, XML Web services, distributed components, client-server applications, database applications, and much, much more.The course will teach you topics like:Setting up various development environmentsVariablesData TypesString operatorsAssignment operatorsComparison operatorsLogical operatorsArraysFunctionsListsConcatenationConditional StatementsWe will be creating 16 projects - 4 for each of the programming languages."

"Elixir for beginners"

"Elixir is a dynamic, functional language designed for building scalable and maintainable applications. It leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.Elixir is a functional, dynamic language built on top of Erlang and the Erlang VM. Erlang is a language that was originally written in 1986 by Ericsson to help solve telephony problems like distribution, fault-tolerance, and concurrency. Elixir, written by Jos Valim, extends Erlang and provides a friendlier syntax into the Erlang VM. It does this while keeping the performance of the same level as Erlang.Features of ElixirScalability All Elixir code runs inside lightweight processes that are isolated and exchange information via messages.Fault Tolerance Elixir provides supervisors which describe how to restart parts of your system when things go wrong, going back to a known initial state that is guaranteed to work. This ensures your application/platform is never down.Functional Programming Functional programming promotes a coding style that helps developers write code that is short, fast, and maintainable.Build tools Elixir ships with a set of development tools. Mix is one such tool that makes it easy to create projects, manage tasks, run tests, etc. It also has its own package manager - Hex.Erlang Compatibility Elixir runs on the Erlang VM giving developers complete access to Erlangs ecosystem.Topics covered in this course includes:Installing ElixirDisplaying outputElixir build toolApplication structureCreating a new elixir projectReading from afileInjecting a file into elixir projectCreating a custom taskUsing elixir packagesData typesOperatorsusing Elixir MapVariablesFunctions and ModulesFiltering dataSorting data"

"Logic Pro X: Dj Snake EDM Music Production in Logic Pro X"

"Do you like the style of Dj Snake and the process of ""modern"" EDM music production? Do you struggle to lay out ideas and to get inspiration quickly for your EDM track in Logic Pro X? Are you running in to writers block easily these days? Then this course is for you!Welcome to this course where I will learn you how to create electronic music in the style of Dj Snake. In this course - you will learn how to create a ""modern"" EDM track fast and how to get ideas quickly. In just a few hours you will learn how to overcome writers block and arrange your track fast. Logic Pro X Template is included for FREE! We also included FREE Sample Packs as a Bonus!These Sample Packs are included:4 Project Ideas for Logic Pro X1 Full BONUS Deep House Project1 Original Logic Pro X Project File (The one that you will learn creating in this course)Snare Rolls Pack 1 - 70 Snare Rolls Samples - Complete Snare Rolls to use in your next project.Up & Downlifters 1 - 50 FX Samples for great transitions between different parts in your song.Kick Toolbox 1 - 100 Professional Kick Drum Samples in different pitch.Reversed Reverbs - 120 Reversed Reverb Effects to use to introduce parts in your arrangement.One Shot EDM Samples - 50 Synth & Bass Samples to use in a Sampler for Professional Sounds in no time!One Shot Deep House Samples - 50 Synth & Bass Samples to use in a Sampler for Professional Sounds in no time!Clap & Snare Toolbox + MIDI Groovy Tools.I have produced electronic music for a long time - over 10 years now - and a few years ago I got to a point where I couldn't get past writers block and I didn't know what to produce anymore. The genre ""Electronic Music"" started to get generic and after a while the style got slower in tempo - from 128BPM to 110BPM and even slower. After trying to experiment with tempo and different style I became a lot more inspired to create music again. A whole new world opened up to me. I just wish that someone would tell me how to do these different tricks and how to experiment without thinking so much about whats wrong and what right. This course will help you a lot - take it as a guideline at the same time as creating a track that is ""Modern"".In this course you will learn:How to produce a full track from scratch to finish.How to get from a short musical idea - an 8-bar loop - to a full track.How to make transitions from different places in your track so you get a natural and professional sound.How to mix and master a track so it sounds good on every place you play your track.You will get the finished Logic Pro X project file (.lpx file) that you can download and open on your computer.We will first go through an initial idea process, or a creative process where we just throw every sound that we like in to the project. Without any rules at all, just whatever we feel sounds great at that moment. I think that it is important to be creative when creating music since music is an creative art after all.After that we will go over organising the project and arrange the track even though we don't have all the sounds for our final project yet or we're not 100% happy with the sounds yet. I think it's really important to create a first arrangement or how I call it ""the skeleton of the track"". This is so we can see visually how our track will look like when it is done. Now it's a lot easier to see what sounds we should add where in the track.When we are done adding more sounds that we like and adding FX's such as transition elements so our track sounds more alive and not that static - then we are going to the finishing process of the track.Mixdown and mastering sections are also fully covered in this course so we can listen to our tracks on every sound system there is out there like you car speaker, Spotify or a big club sound system. We are going through the process on how to have it mixed down properly.So what are you waiting for? Lets see you in the course :)"
