Oracle 23ai与Oracle 19c相比,有几个显著的亮点:1. AI Vector Search:Oracle 23ai引入了AI Vector Search,这是一种强大的新技术,允许您使用新一代AI模型来生成和存储向量。这些向量可以是文档、图像、视频、声音等的多维表示。通过将这些对象编码为向量,您可以使用数学计算来寻找它们之间的相似性。2. AI for Data:Oracle 23ai的目标是两方面的:一是使应用开发者更容易地将AI功能添加到他们的数据驱动应用中;二是将GenAI能力整合到我们的产品中,使所有Oracle数据库的用户,从数据分析师到应用开发者和DBA,都能更高效地工作。3. 开发者友好的新特性:Oracle 23ai还为开发者提供了新的特性,使构建下一代应用变得更简单,这些应用可以使用JSON或关系型开发方法,或者两者交替使用。4. 数据库功能优化:Oracle 23ai还利用AI优化了许多关键的数据库功能,以便更准确地估计时间和资源成本。5. SQL改进:在SQL方面,Oracle 23ai引入了一些改进,例如添加了两种新的数据类型“Boolean”和“Vector”,增加了“Data Usecase Domains”以丰富表定义中使用的数据类型的含义,简化了简单SQL语句中“from dual”的需求,以提高可读性,使得在“interval”数据类型上聚合变得更容易,引入了表值构造器,以便在insert select或merge语句中轻松指定多行。这些亮点展示了Oracle 23ai如何将AI集成到数据库中,为开发者和企业提供了更多的可能性和便利。 那么相比oracle 19C,oracle 23ai新增了哪些数据库参数呢?请看详细参数列表:
