1.Linear data structuresare arranged on a single level sequentially (linearly). The data structure is easy to implement and traverse because it imitates computer memory arrangement. Linear data structures branch further into two subcategories based onmemory allocationchanges: Static data structureshave a...
Since database instances are just a snapshot at a given moment, they’re likely to change over time, unlike database schemas. 在某一时刻来自数据库的数据样本称为数据库实例。它包含架构描述为数据值的所有属性。由于数据库实例只是给定时刻的快照,它们可能会随着时间的推移而变化,这与数据库模式不同。
