    1.) There have been several versions of SQL created in the last 26 years. In 1986, SQL-86 (SQL-87) was first published. In 1989, SQL-89 was a minor revision made to the original SQL. In 1992, SQL-92 (SQL2) was a major revision to its previous version. In 1999, SQL-99 (SQL3) added regular expression matching, recursive queries, triggers, non scalar types and some object oriented features. In 2003, SQL-2003 introduced XML related features, standardized sequences, and columns with auto generated values. In 2006, SQL-2006 defined ways in which SQL can be used in conjunction with XML and it defined ways of importing and storing XML data in an SQL database, manipulating it within the database and publishing both XML and conventional SQL-data in XML form. It also enables applications to integrate into their SQL code the use of XQuery. In 2008, SQL-2008 Legalized ORDER BY outside cursor definitions, added INSTEAD OF triggers, and added the TRUNCATE statement. As of March 2012, the newest SQL was released its new features include AlwaysOn SQL Server Failover Cluster Instances and Availability Groups which provides a set of options to improve database availability, Contained Databases which simplify the moving of databases between instances, new and modified Dynamic Management Views and Functions, programmability enhancements including new Spatial features, Metadata discovery, Sequence objects and the THROW statement, performance enhancements such as ColumnStore Indexes as well as improvements to OnLine and Partition level operations and security enhancements including Provisioning During Setup, new permissions, improved role management and default schema assignment for groups…

    With the Simulation software, it is relatively easy to change the features or price point of a product and have the simulation software predict the market share that the product would attain in the market. This I hope to achieve by using the computer to emulate a real world situation. It is time based, and takes into account all the resources and constraints involved, as well as the way these things interacts with each other as time passes. Simulation also builds in the randomness that would be seen in real life. For instance, it doesn’t always take exactly 5-minutes for a customer to be served and a customer don’t always arrive every 15-minutes. This means that the simulation really can match reality, so when one make changes to the simulation; it will demonstrate exactly how the system would behave in real life.…
