Oracle SQL Tutorial 1 - Intro to Oracle Database
As illustrated in the video, Oracle Database is a program designed to hold lots of information, or data. There are all kinds of different databases and they all have their uses. Some of the most common ones are MySQL, SQL Server, Sybase, and MongoDB. All of these have different uses. The differences will be easier to understand after you learn more about each kind of database. We did not discuss it much in the video, but if you are wondering what “SQL” means in the title, it stands for structured query language. Structured query language is a human readable computer language that is used to tell databases to do things. We will discuss SQL and Oracle SQL Developer more in future videos. Databases are better than spreadsheets because they allow multiple users at one time, different levels of access given to users, recovery options and transactions, and it is more protected from hacking and malicious destruction. Programming languages often have very useful functions or methods that can be used to communicate to a database and therefore they are a naturally good option for the back end of programs. This course will go over all of the major parts of database programming using Oracle SQL. We will be using Oracle 11g, but these videos should still work with other versions, including the most recent 12c. Q and A ~~~~~~ How much does Oracle cost? The full enterprise edition costs thousands. They have other versions for less and they even have a FREE VERSION! This is known as the XE version (eXpress Edition). That is the one we will be using. How long does it take to learn SQL? You can learn all of the basics and be an efficient beginner database developer in only about a month of practice. To become an intermediate it can take anywhere from an additional 3 - 6 months with a only a few hours of studying and practicing each day. How can I learn SQL faster? Take notes and actually mess around with making your own database. Watch these videos until you understand the concepts within them, read articles and books that teach in more depth.

1.Introduction to basic SQL*Plus and SQL commands in oracle 9i
A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as invented by E. F. Codd, of IBM's San Jose Research Laboratory. Many popular databases currently in use are based on the relational database model.RDBMSs have become a predominant choice for the storage of information in new databases used for financial records, manufacturing and logistical information, personnel data, and much more since the 1980s. Relational databases have often replaced legacy hierarchical databases and network databases because they are easier to understand and use. However, relational databases have been challenged by object databases, which were introduced in an attempt to address the object-relational impedance mismatch in relational database, and XML databases. Object-relational database management system (ORDBMS) ============================================ An object-relational database can be said to provide a middle ground between relational databases and object-oriented databases (OODBMS). In object-relational databases, the approach is essentially that of relational databases: the data resides in the database and is manipulated collectively with queries in a query language; at the other extreme are OODBMSes in which the database is essentially a persistent object store for software written in an object-oriented programming language, with a programming API for storing and retrieving objects, and little or no specific support for querying. Object-relational database management systems grew out of research that occurred in the early 1990s. That research extended existing relational database concepts by adding object concepts. The researchers aimed to retain a declarative query-language based on predicate calculus as a central component of the architecture. Probably the most notable research project, Postgres (UC Berkeley), spawned two products tracing their lineage to that research: Illustra and PostgreSQL. Many of the ideas of early object-relational database efforts have largely become incorporated into SQL:1999 via structured types. In fact, any product that adheres to the object-oriented aspects of SQL:1999 could be described as an object-relational database management product. For example, IBM's DB2, Oracle database, and Microsoft SQL Server, make claims to support this technology and do so with varying degrees of success. SQL(Structures Query Language) ======================== SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.The acronym SEQUEL was later changed to SQL because "SEQUEL" was a trademark of the UK-based Hawker Siddeley aircraft company. SQL*Plus ======= SQL*Plus is a command line SQL and PL/SQL language interface and reporting tool that ships with the Oracle Database Client and Server software. It can be used interactively or driven from scripts. SQL*Plus is frequently used by DBAs and Developers to interact with the Oracle database. If you are familiar with other databases, sqlplus is equivalent to: "sql" in Ingres, "isql" in Sybase and SQL Server, "sqlcmd" in Microsoft SQL Server, "db2" in IBM DB2, "psql" in PostgreSQL, and "mysql" in MySQL.

Also grab my nice DISCOUNT on my SQL for FinTech job seekers course: https://goo.gl/jZHfVe This video answers: What is SQL? How is SQL used? What is a database? Why use a database instead of a spreadsheet? These videos have an intrinsic cost of about $1000 to make so if you enjoy them, please consider donating so that I can make more videos on a more regular basis! It's not just standing up and talking. It could be weeks of planning/research, then multiple takes, then hours of editing then responding to comments. Don't forget the thousands spent on the equipment used. I've spent a lot of money on the equipment I use to shoot/edit these and when they fail (which they are), I have to spend even more money to replace then. Then there is the fact I use up all my free time to do videos now. I have put aside friends and family to focus on this because I feel this is my calling to help others. My job is also very demanding and always comes first, so that leaves little time for videos. Thanks! https://www.paypal.com/cgi-bin/webscr... Part 2: https://goo.gl/ppQz9r NOTE: SQL combines the roles of data definition, data manipulation, and query in a single language.

NoSQL Database Tutorial for Beginners
Learn how NoSQL databases work and learn when NoSQL is a better option than standard relational databases, and just as importantly when it’s not. We will also walk through some of the popular forms of NoSQL databases and how you can access them for your applications in this NoSQL Tutorial for Beginners. So first and foremost: what are NoSQL databases and why should I care about them? The easiest way to understand the definition is that NoSQL databases are not SQL databases. Standard relational SQL databases such as Oracle’s SQL server or MySQL have a tabular structure, similar to what you’d see in an Excel spreadsheet. Whereas NoSQL databases have various types of formats and can therefore be more flexible. For example, imagine that you had to build an application where users were able to define their own fields, such as a survey application where one user may create a survey with two fields and another may create a survey with a hundred fields, and they need to have the ability to be named on the fly. Technically it would be possible to implement this with a relational database, however it would be very clunky. However NoSQL databases could handle this easily, by allowing the fields to be created dynamically and then each record would could be stored with its unique characteristics. It’s important to note that one of the greatest strengths of NoSQL, it’s flexibility, also presents its greatest challenge. Imagine that you are building out an inventory application that has fields that need to connect to other tables, such as a user table for the employee entering the information, a vendor table, and a tax table to calculate depreciation. If you were to attempt to implement a NoSQL database for this inventory option you’d end up having to work very hard to map the values between the models and it would also make for a very difficult application to maintain. In this case study a relational database (rdms) would work perfectly. So when you’re trying to decide on NoSQL database design, it really comes down to what the requirements of the application are. If you wanted to chop a tree down you wouldn’t use hammer, you’d use an axe because it’s basic common sense to utilize the right tool for the right job. And it’s the same way with software development, I don’t believe in the SQL vs NoSQL debate, they are both tools and they are the most effective when used in an application that works well with their strengths. A good rule of thumb is to simply follow the guidelines given by the names themselves: - If you have data that relies heavily on relationships then it’s probably the best fit to utilized a relational SQL database. - If you have an unstructured data set that needs flexibility, than it may be the best option to go with a database that is Not SQL, such as a NoSQL database.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

SQL Queries with JOINS for dummies
To work with WFA, I often say, you don't have to be a developer, and I stick with that statement. However, when we want some decent userinput, we will have to write a SQL Query every now and then, and although a simple select query is easy to learn, whenever I start talking about "JOINS", they tend to get lost. In this tutorial I will try to teach you why we need joins and how they work.

Как изучать язык SQL и работу реляционных баз данных начинающему: видео уроки курсы книги учебники.
Помощь проекту: WMR: R288272666982 WMZ: Z293550531456 Яндекс.Деньги: 410011531129223 Рубрика SQLite на сайте: http://zametkinapolyah.ru/zametki-o-mysql/sqlite/ Паблик блога в ВК: https://vk.com/zametkinapolyah Тематическая группа в ВК: https://vk.com/zametki_bd Если вы хотите быть SQL-разработчиком, администратором или архитектором баз данных: 1. Здесь можно выделить четыре основных направления. а) теория реляионных баз данных и реляционная алгебра/алгоритмы и структуры данных/дискретная математика; б) необохдимо изучить инструмент, который будете применять в работе (стандарты читать не надо, а вот активное юзанье документации пойдет на пользу); в) получение практики: повторение примеров из книг и видео уроков, разбор архитектуры БД и Query-листа приложения с открытым исходным кодом, самостоятельный выбор любого объекта (предметной области) из нашего бренного мира и его описание, это может быть даже дом, в котором вы живете; г) изучение предметной области, в которой вы хотите работать. 2. Если у вас нет даже базовых знаний, то начинать нужно с простых и понятных материалов, которые не отобьют у вас желание учиться и позволят почувствовать уверенность в своих силах и понять, что базы данных и SQL - это не так уж и сложно. Для этих целей прекрасно подойдут материалы, которые вы сможете нагуглить или видосы с Ютуба, благо этого добра навалом. Книги по SQL и базам данных для новичка: «Изучаем SQL», Бейли Л.; «SQL для простых смертных», Грабер Мартин; «SQL за 10 минут», Бен Форта; «Изучаем SQL», Алан Бьюли; «Язык запросов SQL. Учебный курс», Филипп Андон, Валерий Резниченко; «SQL For Dummies», Allen G. Taylor «SQL-запросы для простых смертных. Практическое руководство по манипулированию данными в SQL», Майкл Дж. Хернандес, Джон Л. Вьескас; «MySQL. Сборник рецептов», Поль Дюбуа. Документация самых популярных СУБД: документация SQLite: http://sqlite.org/docs.html; документация MySQL: https://dev.mysql.com/doc/ документация PostgreSQL: https://www.postgresql.org/docs/9.6/static/index.html; документация PostgreSQL на русском: https://postgrespro.ru/docs/postgresql/9.6/; документация MS SQL: https://technet.microsoft.com/ru-ru/library/ms130214.aspx; документация Oracle: http://docs.oracle.com/cd/E11882_01/index.htm; сюда можно добавить книги по различным СУБД, ориентированные на читателя со средней и высокой подготовкой; и, конечно же, учебник и словарик английского языка, если вы его не знаете. Теоретические знания: уровень Будда SQL и реляционных баз данных Книги по теории реляционных баз данных: «Введение в системы баз данных», Кристофер Дж. Дейт «SQL и реляционная теория. Как грамотно писать код на SQL», Кристофер Дж. Дейт «Основы будущих систем баз данных: Третий манифест»., Кристофер Дж. Дейт «Базы данных и UML», Роберт Дж. Мюллер «Теория и практика построения баз данных», Крёнке Д. «Системы баз данных: проектирование, реализация и управление.», Питер Роб, Карлос Коронел «Системы баз данных. Полный курс.», Гектор Гарсиа-Молина, Джеффри Ульман, Дженнифер Уидом Книги по алгоритмам и структурам данных: «Алгоритмы. Вводный курс», Томас Х. Кормен; «Алгоритмы», Дасгупта С., Пападимитриу Х., Вазирани У.; «Анализ алгоритмов. Вводный курс», Дж. Макконелл; «Алгоритмы. Теория и практическое применение», Род Стивенс; «Автоматное программирование», Поликарпова Н. И., Шалыто А. А.; «Алгоритмы и структуры данных. Новая версия для Оберона», Н. Вирт; «Алгоритмы. Построение и анализ.», Т.Кормен, Ч.Лейзерсон, Р.Ривест, К.Штайн; Книги и учебники по дискретной математике: «Дискретная математика для программистов», Р. Хаггарти; «Введение в схемы, автоматы и алгоритмы», Дехтярь М. И.; «Графы и алгоритмы», Алексеев В. Е., Таланов А. В.. Где, черт возьми, мне брать практику? Повторяйте примеры из книг, учебников, видео. Оглянитесь вокруг: любой предмет, который вы видите, можно описать в базе данных, например, ваш дом, жэк и его жильцы. Ну хорошо, сделайте базу данных для КЛАДР и нормализуйте ее до улицы или сделайте базу данных всех номеров для всех провайдеров во всем мире или России (при этом учтите номера спец. служб, деление на мобильные и стационарные, да, номера еще и внутри страны делятся по регионам и есть всякие 8 800). Мы пришли к тому, что перед проектированием БД нужно хоть чуток разбираться в предметной области, для тех кто хочет сделать КЛАДР: не забывайте, что Москва – это не только город. Если вы хотите проектировать базы данных для Web, то скачайте самые популярные и востребованные CMS (Drupal, WordPress, Joomla, Typo3) и посмотрите на их базы данных, а также изучите запросы к базам данных, это полезная практика. Если вас интересует другая предметная область – Гугл вам в помощь, вы сможете найти различные биллинговые системы, CRM, ARM и другие системы учета с открытым исходным кодом и документацией.
Subqueries in sql   Part 59
In this video we will discuss about subqueries in sql server. Let us understand subqueris with an example. Please create the required tables and insert sample data using the script below. Create Table tblProducts ( [Id] int identity primary key, [Name] nvarchar(50), [Description] nvarchar(250) ) Create Table tblProductSales ( Id int primary key identity, ProductId int foreign key references tblProducts(Id), UnitPrice int, QuantitySold int ) Insert into tblProducts values ('TV', '52 inch black color LCD TV') Insert into tblProducts values ('Laptop', 'Very thin black color acer laptop') Insert into tblProducts values ('Desktop', 'HP high performance desktop') Insert into tblProductSales values(3, 450, 5) Insert into tblProductSales values(2, 250, 7) Insert into tblProductSales values(3, 450, 4) Insert into tblProductSales values(3, 450, 9) Write a query to retrieve products that are not at all sold? This can be very easily achieved using subquery as shown below. Select [Id], [Name], [Description] from tblProducts where Id not in (Select Distinct ProductId from tblProductSales) Most of the times subqueries can be very easily replaced with joins. The above query is rewritten using joins and produces the same results. Select tblProducts.[Id], [Name], [Description] from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId where tblProductSales.ProductId IS NULL In this example, we have seen how to use a subquery in the where clause. Let us now discuss about using a sub query in the SELECT clause. Write a query to retrieve the NAME and TOTALQUANTITY sold, using a subquery. Select [Name], (Select SUM(QuantitySold) from tblProductSales where ProductId = tblProducts.Id) as TotalQuantity from tblProducts order by Name Query with an equivalent join that produces the same result. Select [Name], SUM(QuantitySold) as TotalQuantity from tblProducts left join tblProductSales on tblProducts.Id = tblProductSales.ProductId group by [Name] order by Name From these examples, it should be very clear that, a subquery is simply a select statement, that returns a single value and can be nested inside a SELECT, UPDATE, INSERT, or DELETE statement. It is also possible to nest a subquery inside another subquery. According to MSDN, subqueries can be nested upto 32 levels. Subqueries are always encolsed in paranthesis and are also called as inner queries, and the query containing the subquery is called as outer query. The columns from a table that is present only inside a subquery, cannot be used in the SELECT list of the outer query. Next Video: What to choose for performance?

Entity Relationship Diagram (ERD) Tutorial - Part 1
Learn how to create an Entity Relationship Diagram in this tutorial. We provide a basic overview of ERDs and then gives step-by-step training on how to make an ER diagram with correct cardinality. Entity Relationship Diagrams are comprised of 3 main categories: entities, attributes, and relationships. Entities are objects or concepts that are associated with important data—like a customer, order, or product. Attributes represent properties or traits of an entity, such as a customer’s phone number or home address. Relationships demonstrate the link between entities. Another main aspect of of ERD's is cardinality, which further defines the relationship between entities in a numerical way. Certain symbols signify the minimum and maximum relationship between different entities.
