PostgreSQL与Oracle

PostgreSQL和Oracle是两个著名的关系数据库，其中PostgreSQL是开源RDBMS，而Oracle是商业RDBMS ，有各种版本。

在本节中，我们将基于各个方面来讨论PostgreSQL和Oracle数据库系统之间的差异。

什么是PostgreSQL?

PostgreSQL是最流行的对象关系数据库管理系统，用于管理关系数据库并安全地存储它。它是开源数据库软件，初始数据库提供了多版本并发控制(MVCC)功能。

PostgreSQL支持各种操作系统，例如Microsoft Windows ，UNIX，Mac OS X， LINUX等。它遵循事务以及ACID属性(即原子性，一致性，隔离性和持久性) 。

什么是Oracle?

Oracle是第一个为使用查询语言部署数据的商业目的而建立的数据库软件。它是一个跨平台的数据库系统，可以在多个操作系统上执行。

这是一个商业关系数据库系统，允许安全，快速地存储和检索数据。对于数据库开发和中间层软件的运营，Oracle开发了一些工具，例如HCM(人力资本管理)，SCM(供应链管理)，ERP(企业资源计划)和CRM(客户关系管理)软件。

让我们看一下PostgreSQL和Oracle之间的一些本质区别，这将有助于我们增强知识：

Different Aspects PostgreSQL Oracle
Definition It is an object-relational database management system that is compatible with various SQL features such as subqueries, foreign keys, and triggers.
Also, it supports multiple user-defined types and functions.		 Oracle is a commercial relational database management system. It has secondary database models like the document store, key-value store, RDF store, and graph DBMS.
Programmed or Written in It has primarily written in C language. It has primarily written in C and C++ languages.
Developed The PostgreSQL global development group develops it. Oracle develops it.
Released PostgreSQL was released in 1996. Oracle was released in 1980.
Latest release version The latest release version is PostgreSQL 12.3 [May 2020] The latest release version is 19c [February 2019]
License PostgreSQL is an open-source tool. Oracle is a commercial tool.
Programming languages It is compatible with various programming languages such as C, C++, Java, .Net, Perl, Python, Tcl, JavaScript (Node.js), and PHP. Oracle supports various programming languages such as C, C++, C#, Cobol, Java, JavaScript, Lisp, Perl, PHP, Python, R, Ruby, Tcl, Scala, Visual Basic, and so on.
Handling large data volume It handles a massive amount of data efficiently, and that increases the productivity of the software. The enterprise version of the Oracle database handles a vast amount of data successfully as compare to PostgreSQL.
Features Following are the characteristics of PostgreSQL:
  • It supports various programming languages.
  • It is free to download.
  • It supports multiple features of SQL.
  • It is highly extensible.
  • It is compatible with Data Integrity.
  • It is highly reliable.
  • Compatible on several operating systems.
 Following are essential features of an Oracle database:
  • Oracle is portable, scalable, programmable, distributed software.
  • It can handle a large amount of data quickly.
  • It is compatible with ACID property, which allows us to keep the reliability and integrity of our data.
  • It supports a logical database structure.
  • It has networking stacks which enable us to communicate applications through multiple platforms with oracle database easily.
  • Oracle provides a recovery manager tools.
Productivity It contains less number of transactions per second as compared to Oracle Database that’s why it is less productive than Oracle database. It contains more transactions per second compared to PostgreSQL; that’s why it increases the productivity based on its technical advantages.
Platforms Primarily it supports Unix, Window, Linux, FreeBSD, HP-UX, NetBSD, OpenBSD, OS X, and Solaris. Primarily it is compatible with several operating systems like Windows, AIX HP-UX, Linux, Mac, Solaris, etc.
Scalability It provides the scalability support for free of cost developments like cluster-based storage solutions, substitution from Skype allocating information in database collections depends on the PostgreSQL. It supports four sockets with standard edition for scalability. However, for high workload projects, we need to purchase a slightly expensive original version.
Server-side scripting It is compatible with user-defined functions. It supports PL/SQL.
Security It provides excellent security support, but not that much advanced as Oracle database. It provides advanced security as compare to PostgreSQL; however, we need to buy the enhanced versions of Oracle that contain those features which help us to protect the database.
In memory competences PostgreSQL does not have memory capabilities. Oracle does have memory capabilities.
Customer Support In PostgreSQL, the customer support is free, but it will take some time to solve the problem as the developer’s community will resolve it. We can also buy the paid service PostgreSQL, which is less expensive than Oracle Database customer support price. In Oracle, the customer support is not free as it is nearly 1/4 of the license price and increases 3-5 percentage yearly.
Other accessing methods and APIs In PostgreSQL, we can access the following methods JDBC, ODBC, native C library, ADO.NET, and streaming API for large objects. In Oracle, we can access the following methods, including ODBC, OCI (Oracle Call Interface), JDBC, and ODP.NET.
Updates The developer’s group of PostgreSQL releases the updated new versions once in 4-5 years. Still, they always enhance new features and update them according to customers’ needs and market developments. It releases the new or updates the versions of the oracle database once in 2-3 years with quality modification as per the market trends.

总览

在了解了PostgreSQL和Oracle之间的区别之后，我们可以说PostgreSQL在各种情况下都比Oracle更有效，因为它是开源软件，与新的Relational数据库管理系统兼容，并且易于与大量开发人员一起使用。众所周知，PostgreSQL已在企业对企业应用程序，患者基因和医院应用程序等多个组织中使用。我们可以根据实际项目需求选择数据库。
