1. 弹性搜索:
它是一个分布式搜索和分析引擎。它是开源的,可以用于所有类型的数据。它是用Java编程语言实现的,支持所有具有Java虚拟机(JVM)的操作系统。它是Elastic的主要组件Stack,这是一个用于数据分析和可视化的开源应用程序。它具有很高的可扩展性,执行动作的速度也很高,这使其成为数据分析、处理和可视化的简单快捷的工具。

2. IBM DB2:
它是 IBM 于 1983 年开发的关系数据库。它被认为是为 AI 构建的数据库管理产品家族。它具有增强的执行交易的能力。它基于ACID的原理工作,具有很高的灵活性和性能。它具有高效的备份设施,被认为非常安全。它非常可靠,并得到 Linux、Unix 和 Windows 操作系统的支持。它具有商业许可证,具有很高的可扩展性。

Elasticsearch 和 IBM DB2 的区别:

S.NO. Elasticsearch IBM DB2
1. Elasticsearch is a search and analytics engine based on Apache Lucene. IBM DB2 is a relational database model.
2. The primary database model is a search engine. Primary database model is document store and RDF store in IBM DB2.
3. It has no concept of transactions. It has concept of transactions satisfying ACID properties.
4. It was developed by ELASTIC in 2010. It was developed by IBM in 1983.
5. It is schema free. Schema is present in IBM DB2.
6. It has ES-Hadoop connector type map reduce. It does not have map reduce concept.
7. It is implemented in java. It is implemented in C and C++ languages.
8. It has Java API, RESTful HTTP/JSON API. It has ADO.NET, JDBC, ODBC, Xquery, JSON style queries.
9. It is considered less than IBM DB2 in terms of ranking. It is considered better than Elasticsearch in terms of ranking. 10. It accepts all operating systems having JVM. It supports AIX, HP-UX, Linux, Solaris, Windows, z/OS.
