Subject: SQL Programming
Why should I learn SQL?
#1) Data Mining Learning SQL will allow you to mine data with greater efficiency. #2) SQL Programmers in High Demand You shouldn’t have a problem finding a job as an SQL programmer. #3) Data Manipulation SQL is particularly effective at data manipulation. #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. #5) Manage Large Pools of Data 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. #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.
