sql和nosql区别

Here you will learn about difference between sql and nosql or sql vs nosql.

在这里，您将了解sql和nosql或sql vs nosql之间的区别。

Both are a complete different concept, which could be better understood by the following explanation.

两者都是完全不同的概念，可以通过以下解释更好地理解。

SQL

SQL

SQL or the Structured Query Language is a Database language for storing, retrieving and accessing database. SQL stores data in the form of data-tables i.e. SQL is a relational database system (RDBMS). It contains queries like commands through which we can get to access, retrieve and manipulate our data.

SQL或结构化查询语言是一种用于存储，检索和访问数据库的数据库语言。 SQL以数据表的形式存储数据，即SQL是关系数据库系统(RDBMS)。 它包含诸如命令之类的查询，通过这些查询我们可以访问，检索和操纵我们的数据。

These commands are standardized for the making the migration of projects easy from one system to the other.

这些命令是标准化的，以使项目从一个系统轻松迁移到另一个系统变得容易。

For instance: The SELECT command is used to select particular records from the given or designated table. It is used to select only those records which we need to perform any action on. The selected records are then stored in the result-set and any action (if required) is performed on only those records.

例如：SELECT命令用于从给定或指定的表中选择特定的记录。 它仅用于选择需要对其执行任何操作的那些记录。 然后，选定的记录将存储在结果集中，并且仅对那些记录执行任何操作(如果需要)。

Likewise, many more commands are available with the SQL which makes us communicate with our database easily and thus in a way handles our database for us.

同样，SQL提供了更多命令，这使我们可以轻松地与数据库通信，从而以某种方式为我们处理数据库。

SQL is used to build complex databases which have the capability to handle large amount of data in structured format.

SQL用于构建复杂的数据库，这些数据库具有处理结构化格式的大量数据的能力。

NoSQL

NoSQL

As the name suggests “NoSQL” is just the opposite of SQL. All the features are reversed in NoSQL.

顾名思义，“ NoSQL”与SQL相反。 在NoSQL中，所有功能都被颠倒了。

NoSQL on the other hand is a non-relational database management system. NoSQL is used for developing database for companies with low budget and small amount of data to work on. NoSQL has greater flexibility than SQL because it stores data in the form of graphs, charts, objects ad offers a room for new data entries to be accommodated easily in the database despite of their uniqueness.

另一方面，NoSQL是非关系数据库管理系统。 NoSQL用于为预算较低且需要处理少量数据的公司开发数据库。 NoSQL比SQL具有更大的灵活性，因为它以图形，图表，对象的形式存储数据，尽管它们具有独特性，但为将新数据条目轻松容纳在数据库中提供了空间。

But database researchers seek this flexibility as a misguiding feature when it comes to cross platform migration of such databases.

但是，数据库研究人员在进行此类数据库的跨平台迁移时，将这种灵活性作为错误的功能。

One more point of difference is the lack of standardization of the database query formats. This is another issue that needs to be solved to popularize NoSQL. With this, NoSQL also requires a documentation rich community for problem solving and with easy to learn tutorials to guide new developers take the advantage of this emerging technology.

另一个不同点是缺乏数据库查询格式的标准化。 这是普及NoSQL需要解决的另一个问题。 因此，NoSQL还需要一个文档丰富的社区来解决问题，并通过易于学习的教程来指导新开发人员利用这一新兴技术。

Some of the NoSQL database management systems are:

一些NoSQL数据库管理系统是：

• MongoDB

• BigTable
