PRIV P35e Lists

Definition: List

A list is a collection of one or more items, separated by comma.

Item: An item is one or multiple words.

Lists on DB

Table / Attribute where lists are stored.

Are items stored seperatedly?

Types of lists

Dimension 1:

1. Stop Word List: We have multiple stop words lists depending on the grammar of the language.The following 2 and 3 are Non-Stop Word Lists
2. Key Phrases: Usually entered manually on a master list.
3. Tag-Based List: The words in the list are tags. Tag-based lists
   cannot be modified. For a modification one must edit the tags.

Dimension 2: 

• Master List:  Typically users like to enter new words only in a
  single place – called Master.
• Slave List: A slave list is a copy from the master list.

The type of list, i.e. the two dimensions should be a DB attribute on the list.

Functions

Edit list manually

Lists can be edited manually in the above GUI. Update button to save them.

Order list

We have two buttons or two entries in a drop-down list.

Which of the two depends on effort.

1. Order Alphabetically. (default is alphabet ascending). If we use a button, then we might also use alphabet descending
2. Order first by length of the item (ascending), then by alphabet.

Types of Sync

• List Sync: Copy all words from the master list into the slave list
• Tag-based Sync: Copy all tags  from one more WordPress DBs (the masters) into one or more
  tag-based lists (the slaves).

Synchronization Method

• Override: The sync is always a copy that overrides the list on the slave.
• One-Directional: The sync adds all new items from the master to the slave.
  After this operation the slave may have more items than the master.
• Bi-Directional: The sync adds missing items to both slave and master.
