1. SQL (Structured Query Language) is a special-purpose programming language designed for managing data in a relational database management system (RDBMS). The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control. The SQL standard has gone through a number of revisions: SQL-86, SQL-89, SQL-92, SQL: 1999, SQL: 2003, SQL: 2006, SQL: 2008, SQL: 2011. A few things I was able to find was language enhancements for temporal data definition and manipulation, time Period definitions, temporal primary keys, temporal referential integrity, Syntax for time-sliced and sequenced queries on system time tables.

2. Features for Microsoft SQL Server Express supports most of the features and functionality of SQL Server. The following list some of the major features and components that are supported. Stored Procedures, SQL Server Configuration Manager, Views, Replication (as a subscriber only), Triggers, Advanced Query Optimizer, Cursors, SMO/RMO, sqlcmd and osql utilities, Integration with Visual Studio 2005, Snapshot Isolation Levels, Service Broker (as a client only), Native XML support, including XQuery and XML Schemas, SQL CLR, Transact-SQL language support, Multiple Active Result Sets (MARS), Dedicated Administrator Connection, Import/Export Wizard. Although it does not come without its limitations like Maximum memory utilized by SQL Server Database Engine is 1GB, Maximum size of the each relational database is 10 GB, No SQL Profiler, Dedicated admin connection under trace flag, Single CPU (prior to 2008 R2 Express), Maximum number of SQL Server Express instances = 16 on a machine.

Features for Oracle very quiet a bit depending if its Standard Edition One, Standard Edition, or Enterprise Edition. Standard Edition One and Standard Edition only have Oracle fail safe while Enterprise Edition has pretty much
