Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

Provides an example of steps involved in carrying out association rule analysis in R. Association rule analysis is also called market basket analysis or affinity analysis. Some examples of companies using this method include Amazon, Netflix, Ford, etc. Definitions for support, confidence and lift are also included. Also includes, - use of rules package and a priori function - reducing number of rules to manageable size by specifying parameter values - finding interesting and useful rules - finding and removing redundant rules - sorting rules by lift - visualizing rules using scatter plot, bubble plot and graphs R is a free software environment for statistical computing and graphics, and is widely used by both academia and industry. R software works on both Windows and Mac-OS. It was ranked no. 1 in a KDnuggets poll on top languages for analytics, data mining, and data science. RStudio is a user friendly environment for R that has become popular.

What is it like to use Method R software? In this video presentation, Cary Millsap shows how to use Method R software (the Method R Profiler and Method R Tools) to diagnose and solve a real application performance problem. Thank you to The Pythian Group for hosting and recording the session. This video presentation is the companion of "A First Look at Using Method R Workbench Software," available at http://method-r.com/downloads/doc_view/175-method-r-software-white-paper-1-a-first-look-at-using-method-r-workbench-software?tmpl=component&format=raw. Abstract: Many people underestimate the value and overestimate the difﬁculty of Oracle tracing. Tracing is unique in how well it directly connects objective performance data to enduser performance experiences. This makes it the ideal bridge among a business's users, its software developers, and its operational runtime support staff. With the right understanding and tools, tracing is no more difﬁcult to obtain than other forms of Oracle diagnostic data. This paper demonstrates how to use the Method R Workbench software package to convert trace ﬁles into proﬁles, repair an improperly collected trace ﬁle, use proﬁles to diagnose an Oracle-based software performance problem, predict the effect of proposed remedies upon the end-user performance experience, ﬁx the problem, assess the ﬁx for potential side-effects, and then measure the end-user experience after the ﬁx.

For those of you just getting interested in Big “Data” and/or “Advanced Analytics”, the addition of R through Oracle R Enterprise could leave them wondering "What is R?" R is an open-source language and environment for statistical computing and data visualization, supporting data manipulation and transformations, as well as sophisticated graphical displays. R has been receiving a lot of attention recently, although it’s been around for over 15 years. Corporate data analysts and statisticians often know R and use it in their daily work, either writing their own R functionality, or leveraging existing open source packages, that support a wide range of statistical and data analysis capabilities often specific to individual fields, such as bioinformatics, finance, econometrics, medical image analysis, and others And here is where the second question comes, especially from experts in the field who use R anyway, why use “Oracle’s Enterprise version”?
