 What is a Relational Database? Give the names of any three RDBMS software. (2+3)

Relational Databases

• Databases consisting of two or more related tables are called relational databases

• A typical relational database may have anywhere from 10 to over a thousand tables

• Each column of those tables can contain only a single type of data (contrast this

with spreadsheet columns!)

• Table rows are called records; row elements are called fields

• A relational database stores all its data inside tables, and nowhere else

• All operations on data are done on those tables or those that are generated by table

operations

• Tables, tables, and nothing but tables!

 RDBMS

• Relational DBMS software

• Contains facilities for creating, populating, modifying, and querying relational

databases

• Examples:

–Access

–FileMaker Pro

–SQL Server

–Oracle

Event Handler

An event handler is a command which calls a function when an event happens, such as the user clicking a button

Local Variable

Declaring variables (using the var keyword) within a function, makes them local•They are available only

within the function and hold no meaning outside of it

Scope of Variable

Defining the space in which a variable is effective is known as

defining the scope of a variable. A variable can be either local or global in scope

Array

An indexed list of elements

37.1 RDBMS

• Relational DBMS software

• Contains facilities for creating, populating, modifying, and querying relational

databases

• Examples:

–Access

–FileMaker Pro

–SQL Server

–Oracle

The Trouble with Relational DBs

• Much of current SW development is done using the object-oriented methodology

• When we want to store the object-oriented data into an RDBMS, it needs to be

translated into a form suitable for RDBMS

The Trouble with Relational DBs

• Then when we need to read the data back from the RDBMS, the data needs to be

translated back into an object-oriented form before use

• These two processing delays, the associated processing, and time spent in writing

and maintaining the translation code are the key disadvantages of the current RDBMSes

Solution?
