Which menus do the right mouse button reveal?
On Windows operating systems, the right mouse button (if you are left handed and have the mouse setup for left handed use, it would be the left mouse button) is used to display Context Menus. These menus contain shortcuts to various common commands. In a word processor, it may contains Cut/Copy/Paste commands. In a web browser, it may contain Back/Forward/Stop/Refresh commands. The commands contained within a Context Menu really isn't standard, although many programs that do the same thing as the other may have very similar menus. Its best to check the help documentation for more information. If you are running a version of Linux with a Desktop Manager, the same thing applies. It would all come down to what application you are running.

What commands appear gray instead of black in Excel?
Commands that are not relevant at a particular time will be greyed out. For example, before you do a Paste, you must first have done a Copy or a Cut. If you haven't done either of those, then Paste will be greyed out. Once you Copy or Cut something, then Paste will become black and you can use it. If you have not done anything, then you cannot do an Undo, so it is greyed out. Redo will be greyed out until you have done an Undo. The same applies to many other commands. So commands will be grey or black, depending on what else you have done.

Features of traditional database?
the traditional database do not follow these rulesDr. E. F. Codd's 12 rulesfor defining a fully relational databaseNote that based on these rules there is no fully relational database management system available today. In particular, rules 6, 9, 10, 11 and 12 are difficult to satisfy.Foundation RuleA relational database management system must manage its stored data using only its relational capabilities.Information RuleAll information in the database should be represented in one and only one way - as values in a table.Guaranteed Access RuleEach and every datum (atomic value) is guaranteed to be logically accessible by resorting to a combination of table name, primary key value and column name.Systematic Treatment of Null ValuesNull values (distinct from empty character string or a string of blank characters and distinct from zero or any other number) are supported in the fully relational DBMS for representing missing information in a systematic way, independent of data type.Dynamic On-line Catalog Based on the Relational ModelThe database description is represented at the logical level in the same way as ordinary data, so authorized users can apply the same relational language to its interrogation as they apply to regular data.Comprehensive Data Sublanguage RuleA relational system may support several languages and various modes of terminal use. However, there must be at least one language whose statements are expressible, per some well-defined syntax, as character strings and whose ability to support all of the following is comprehensible:data definitionview definitiondata manipulation (interactive and by program)integrity constraintsauthorizationtransaction boundaries (begin, commit, and rollback).View Updating RuleAll views that are theoretically updateable are also updateable by the system.High-level Insert, Update, and DeleteThe capability of handling a base relation or a derived relation as a single operand applies nor only to the retrieval of data but also to the insertion, update, and deletion of data.Physical Data IndependenceApplication programs and terminal activities remain logically unimpaired whenever any changes are made in either storage representation or access methods.Logical Data IndependenceApplication programs and terminal activities remain logically unimpaired when information preserving changes of any kind that theoretically permit unimpairment are made to the base tables.Integrity IndependenceIntegrity constraints specific to a particular relational database must be definable in the relational data sublanguage and storable in the catalog, not in the application programs.Distribution IndependenceThe data manipulation sublanguage of a relational DBMS must enable application programs and terminal activities to remain logically unimpaired whether and whenever data are physically centralized or distributed.Nonsubversion RuleIf a relational system has or supports a low-level (single-record-at-a-time) language, that low-level language cannot be used to subvert or bypass the integrity rules or constraints expressed in the higher-level (multiple-records-at-a-time) relational language.
