Introduction to NoSQL and Graph Databases
Morpheon的博客
11-30 1078
摘要： 本教程介绍了NoSQL和图形数据库的基础知识，重点探讨图形数据库的特点与应用。NoSQL数据库（包括文档型、键值型、列存储和图形数据库）适用于非结构化或高度关联的数据场景，不同于传统关系型数据库的表格结构。图形数据库以节点和边存储数据，擅长高效查询复杂关系，例如社交网络或推荐系统。相比关系型数据库的多表连接查询，图形数据库通过直接遍历关系提升性能。教程还对比了两种数据库的优劣：关系型数据库成熟稳定、支持ACID事务，适合结构化数据；图形数据库则在关联数据查询中表现更优。最后介绍了Neo4j图形数据库

是 Oracle 11g 中用于修改和删除表中数据的重要 SQL 语句。在操作时，需特别注意数据筛选条件的准确性，以避免意外更改或删除数据。是管理数据表中记录的核心操作，其灵活性和强大功能使其在日常开发中被广泛使用。但在操作时需特别小心，确保筛选条件准确并采取必要的备份与验证措施，以避免因误操作造成数据丢失或不一致。用于更新表中的现有数据，可以更新单行或多行记录，需结合。对关键表进行更新或删除前，建议备份数据，尤其在生产环境中。，将删除表中的所有记录，但表结构仍然保留。可返回更新或删除的行数据。
