The scheme of organizing related information is known as âdata structureâ. The types of data structure are: Lists: A group of similar items with connectivity to the previous or/and next data items. Arrays: A set of homogeneous values.
A relational database organizes data in tables (or relations). A table is made up of rows and columns. A row is also called a record (or tuple). A column is also called a field (or attribute). A database table is similar to a spreadsheet. However, the relationships that can be created among the tables enable a relational database to efficiently store huge amount of data, and effectively retrieve selected data.
