To develop a robust dynamic packaging
application it is important to classify each data source according to its type of
data since the type of data will influence our selection of a solution to achieve data
integration. For dynamic packaging applications, tourism data sources can host
three major types of data: (1) unstructured data, (2) semi-structured data, and (3)
structured data.
Types of Data
Data can be broken down into three broad categories (Figure 4): (1) unstructured, (2)
semi-structured, and (3) structured. Highly unstructured data comprises free-form
documents or objects of arbitrary sizes and types. At the other end of the spectrum,
structured data are what is typically found in databases. Every element of data has
an assigned format and significance.
Unstructured.Data
Unstructured data is what we find in text, files, video, e-mails, reports, PowerPoint
presentations, voice mail, office memos, and images. Data can be of any type and
do not necessarily follow any format, rules, or sequence. For example, the data
present on HTML Web pages are unstructured and irregular.
