➤ Microsoft Excel was developed by Microsoft Corporation in 1994 and is used to present numeric and statistical data in a tabular form. ➤ SQL was developed in the 1970s by IBM researchers Raymond Boyce and Donald Chamberlin to extract, organize, manage & manipulate data stored in relational databases. ➤ Excel is a spreadsheet or worksheet file made of rows and columns that help sort, organize, and calculate numerical data. ➤ SQL is a query language used to manipulate databases and get information stored in a relational database management system (RDBMS). ➤ Excel is helpful for producing quick data summaries and visualizations ➤ SQL is needed to work with large volumes of data, manage databases, and use relational databases to their full potential. ➤ Microsoft Excel is used in business analyst roles for quick calculations, data summaries, and data visualizations. ➤ Data analysts use SQL to take care of large databases and find important and relevant data for business use. ➤ In Microsoft Excel, even slightly more than 100,000 will probably cause your computer to slow down. ➤ SQL does not slow down with larger data sets depending on the software and database. In Excel, your data is saved in a file that is typically set up with tabs, columns, and rows on your computer. ➤ You make SQL queries and send them to the database. The database gets them and either fulfills your requests or changes them. ➤ Excel does not include encryption features for protecting sensitive data such as personally identifiable information, financial data, etc. ➤ The SQL database is designed to be a secure database platform. It has a number of features that can encrypt data, limit access and authorization, and keep data from being stolen, destroyed, or used in other bad ways. ➤ Excel spreadsheets are susceptible to small human mistakes. ➤The most common SQL error is a syntax error.
