SQL Step by Step Videos

Structured Query Language, or what's more commonly known as SQL, is a special-purpose programming language that's used to interact with databases. It works by analyzing and understanding databases consisting of fields of data within tables.

SQL has roots dating back to the early 1970s, during which IBM engineers Donald Chamberlin and Raymond Boyce designed the initial version to the manipulate and retrieve data stored in the company's database system. The two pioneers of SQL called their new language SEQUEL, although they were later forced to change it due to trademark issues. SQL has since become an official standard for the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO).

1) Data Mining

Learning SQL will allow you to mine data with greater efficiency. Using basic queries you can identify specific data at time intervals, view update events, monitor table activity, and much more. This alone should be reason enough to take the initiative and learn SQL.

2) SQL Programmers in High Demand

You shouldn't have a problem finding a job as an SQL programmer. According to the job posting website Job Search | Indeed, there are more SQL programming jobs (in 2016) than any other type of programming language, including Java, JavaScript, C+, Python, C++, and PHP.

3) Data Manipulation

SQL is particularly effective at data manipulation. Because it allows you to see the exact data and how it works, you'll have an easier time testing and manipulating the data. Furthermore, data stored in SQL is dynamic, meaning it can me modified and manipulated at any time using some basic queries.

4) Combine Data from Multiple Sources

Combining data from two or more sources can be time-consuming and downright daunting task. However, SQL makes the process a breeze by supporting simple "merges" in which the specified fields or entire databases are combined.

5) Manage Large Pools of Data

Still searching for a practical way to manage large datasets? Traditional spreadsheets can be used to manage small-to-medium-sized pools of data, but you'll need a different solution when handling excessively large records. Thankfully, this is an area in which SQL shines: whether it's 1,000 records or 100 million, SQL is fully equipped to manage datapools of virtually all sizes.

6) Servers and Databases

If you plan on managing servers, or creating your own server, SQL programming language will most certainly prove useful. Many servers use databases like MySQL or SQL Server to, well, store data. By familiarizing yourself with SQL and its respective queries, you can easily navigate through the otherwise confusing web of datasets.

My mum is abusive and I think is gaslighting me and it has caused me to doubt my own memory these days. What do I do?

I recommend an excellent website and forum called Out of the Fog (outofthefog.net) which is for relatives, spouses etc. of individuals with Cluster B personality disorders. If your mother is gaslighting you and is abusive, it is likely she has a Cluster B disorder. It's very important that you

Every time I cough a little bulge pushes out under my rib cage, I can push it back in with my thumb.. What is going on?

Every time I cough a little bulge pushes out - wherever, I can push it back in with my thumb..Beautiful description of a hernia. Medical students should memorize. The wherever is usually in my groin but it does happen where the muscles arise of the ribs and sternum.Substernal or subxiphiod are exotic but textbook sites.
