A Relational Database.
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.
Yes.
none at all
E. F. Codd introduced the term in his seminal paper "A Relational Model of Data for Large Shared Data Banks", published in 1970. In this paper and later papers he defined what he meant by relational. One well-known definition of what constitutes a relational database system is Codd's 12 rules. However, many of the early implementations of the relational model did not conform to all of Codd's rules, so the term gradually came to describe a broader class of database systems. Relational databases, as implemented in relational database management systems, have become a predominant choice for the storage of information in new databases used for financial records, manufacturing and logistical information, personnel data and much more. Relational databases have often replaced legacy hierarchical databases and network databases because they are easier to understand and use, even though they are much less efficient. As computer power has increased, the inefficiencies of relational databases, which made them impractical in earlier times, have been outweighed by their ease of use. However, relational databases have been challenged by Object Databases, which were introduced in an attempt to address the object-relational impedance mismatch in relational database, and XML databases. http://en.wikipedia.org/wiki/Relational_... http://en.wikipedia.org/wiki/Relational_...
