Why create a database? • Databases: • Sets of related data that
contain information used to organize a collection of (digital ) items • Used to organize
information in such a way that it is easily: • Accessed• Managed • Updated • Via
Database standards • Database standards
make sure info is organized in such a way that future users can easily find info they are looking for.• ---------------------• Looks pretty but only
useful if future user cares about book color and not book content

Relational Data • Relational data is how you let the computer know that fields in
different worksheets/ tables are related • Unique Elements allow the computer program you are using to
understand how to relate data from multiple tables in your workbook to each other • It allows merging of tables and disparate data sets
• So in certain projects you will have a workbook with multiple worksheets• Each worksheet will have an element (like an id number) that will
relate (be the same) to another worksheet in that workbook
Relational Data • Here is an example of how unique elements in each table relate
to at least one other table

What is Metadata? • “…As information
has become increasingly digital, metadata is also used to describe digital data using metadata standards specific to a particular discipline.” via wikipedia
Metadata in everyday life
Example of standardization rules

Example of a metadata standard: Dublin Core
• Dublin Core is a metadata standard used by libraries and archives for digital items that consists of 15 basic fields that can be used to describe any digital object, no matter what it is
Example of a metadata standard: ID3
• "ID3 is a de facto standard for metadata in MP3 files” via wikiepdia • “ID3 tags provide the Title, Artist, Year, Genre and other great information when you're listening to music….
• “An ID3 tag is a data container within an MP3 audio file stored in a prescribed format. This data commonly contains the Artist name, Song title, Year and Genre of the current audio file.” via id3.org
