Use ASP to implement e-cards

The database structure of the e-card program. (This only represents my personal opinion in a certain period of time ).
Table ECARD
The ID of the greeting card.
TITLE of the greeting card
Greeting card author
Greeting card category catalog1
Level 2 catalog2 of greeting cards
The type of the greeting card. The cardtype indicates whether it is a flash card or an image (there may be a JAVA Card)
The name of the big image, of course, can be the name of flash or other files, including the path
Simage
The order_card table is used to store the predefined greeting cards.
The id of the prepaid card is encoded to generate the extracted card key.
Name of the big image: image
Template name: The template is used to store the template name.
Sender name sender
Sender email sendermail
Name of the receiver
Receivermail of the recipient
Check whether the receiving confirmation confirm is used by the sender to choose whether to receive the receipt (I think this is the least necessary, so it is better to reply to him)
The date type data can be used for sending card time senddate. In my opinion, date is a problem that needs to be taken seriously, especially when I encountered problems in date format some time ago.
