Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.

Because equations are part of Science to explain the diversity of it. Example: H2o and other formulas....

A variable in algebra is an unknown quantity as for example in the term 5y the variable is y

The difference of algebra and algebra 1 is that in algebra they teach you the basics. For example, they teach you about variables, graphs, how to find slopes. In algebra 1 they start using equations and and teach you how to work longer equations and all that jazz.

Database = Generic name for a system to store data Relational Database = A specific type of database that utilizes relationships between data to not only store the data but further its efficiency in its manipulation.

There is no such thing as an 'Access' Relational Database.A Relational Database Management System is one that has been built to deliver the requirements set out by Edgar Codd in 1970 such that the functions provided by the software conform to relational algebra. This means that the validity actions of the database management system over the data contained in it can be modeled and proved on a mathematical basis.Oracle, DB2, SQL Server, MySQL, etc. all implement most of the requirements of Codd's paper.It is worth noting that the relational model is the ONLYone where the affects of putting data in it can be proven.

A relational database is a type of database design. Oracle is a brand of database. You can create a relational database using Oracle. You can also create relational databases using other database applications.

Relational Schema refers to meta-data elements which are used to describe structures and constraints of data representing a particular http://wiki.answers.com/Describe_the_differences_in_meaning_between_the_terms_relation_and_relation_schema#. Whereas a relation is a property or predicate that ranges over more than one argumentHere's some translation from "Relational Algebra" to http://wiki.answers.com/Describe_the_differences_in_meaning_between_the_terms_relation_and_relation_schema#terminology:"Relation" = Table."Relation Schema" = Table definition.So for example, the "schema" for the Person "relation" is: Person(FirstName, LastName, Age, Gender, Address)Also in relational Algebra, a "tuple" is a table row, and an "attribute" is a table column.
