logical database name

基本解釋

A logical identifier must not be the same as the name of the physical database.
一個(gè)邏輯的標(biāo)識(shí)不能與物理數(shù)據(jù)庫(kù)的名稱相同。
Ensure that the logical database name is selected (in this example, MAR), and then click Properties.
確保這個(gè)邏輯數(shù)據(jù)庫(kù)名稱已經(jīng)被選中(在這個(gè)例子中是，MAR)，然後點(diǎn)擊 Properties。
Slice does not require such additional schema-level information because it maintains the association between a persistence instance and its original database partition via its logical name.
Slice 不需要這類額外的模式層的信息，因爲(wèi)它根據(jù)持久性實(shí)例的邏輯名維護(hù)了實(shí)例和其原始數(shù)據(jù)庫(kù)分區(qū)間的關(guān)聯(lián)。
