Database & Sequential File Processing

I need to know the best way to answer these questions. I've read the chapters and am clueless to computers. Please provide examples. The book looks like jargon. Thanks.

1. Sequential File Processing:

Give a brief definition of sequential file processing.
Develop an example to illustrate your definition. (The example does not have to be as elaborate. Just a record with a simple explanation)
Describe where sequential file processing might be used.
Discuss the advantages and disadvantages of sequential file processing.

2. Database Processing:

Give a brief definition of database processing.
Develop an example to illustrate you definition. (The example does not have to be as elaborate as in #4 above. Just a few tables with a simple explanation)
Describe where database processing might be used.
Discuss the advantages and disadvantages of database processing.
3. In "5. Data Representation" above several different numbering systems are illustrated.

Please develop your own numbering system using a base number less than 30 and other than 2, 8, 10 and 16. Illustrate your numbering system by completing the "My System" column in #4 above. Make sure to share your base number with us. (see below)
