History of MongoDB and SQL

MongoDB was first developed in 2009 by a company called 10gen (now known as MongoDB Inc.). It was designed as a more flexible and scalable alternative to traditional SQL databases, which became increasingly difficult to work with as data sets grew more extensive and complex.MongoDB was inspired by a document-oriented data model, which several other NoSQL databases had popularized in the early 2000s. The goal was to create a database that could store and query data of any structure without the need to define a fixed schema upfront.

‍

SQL, on the other hand, has a much longer history. It was first developed in the 1970s to manage and manipulate data stored in relational databases. Over the years, it has become the standard language for interacting with relational databases and is widely used in various applications and industries. Despite the differences between MongoDB and SQL, both have become popular choices for developers building modern applications. While MongoDB is often chosen for its flexibility and scalability, SQL databases are still famous for their strong support for transactions and structured data.

‍

What is MongoDB?

‍

‍

MongoDB is an open-source document-oriented database program. It belongs to a family of NoSQL databases, categorized as non-relational databases that do not use the traditional table-based relational database structure. MongoDB uses JSON-like documents with dynamic schemas, making data integration in applications easier and faster. MongoDB is a type of NoSQL database that is used for storing and retrieving data. It is a document-oriented database, which means that it stores data in documents instead of tables. This makes it easier to store and query data that may have different types of attributes. It also makes it more flexible to work with, allowing developers to query and manipulate the data in ways that would be difficult with relational databases.

‍

MongoDB is written in C++ and combines the features of a relational database and a key-value store. It is designed for scalability and high availability, making it an excellent choice for applications that store and process large amounts of data. MongoDB supports ACID transactions, which allow developers to ensure that data is stored and retrieved accurately. It also supports sharding, which divides data into multiple servers to ensure that data is distributed evenly and allows for faster reads and writes. MongoDB is widely used for various applications, such as web applications, mobile applications, content management systems, e-commerce applications, and analytics. It is also used by large organisations such as Google, Facebook, and Uber. MongoDB is a powerful, flexible, and reliable database that can handle large amounts of data. Its features make it an ideal choice for various applications, and many organisations widely use it.

How they are storing data

MongoDB is a NoSQL database that uses a document-oriented data model. This means that data is stored in flexible, JSON-like documents containing any number of fields and having different structures. These documents are stored in collections, similar to SQL database tables. On the other hand, SQL databases use a structured, tabular data model. This means that data is organised into tables, with each table containing a set of rows and columns. Each column in a table has a defined data type and can only contain data of that type. This makes it easy to work with structured data, but it can be more challenging to store and query data of different structures. The way that MongoDB and SQL databases store data is one of the main differences between the two technologies.

‍

‍

1. Data consistency:

• SQL databases are known for their strong support for transactions, which allow multiple related database operations to be executed as a single unit. This makes them well-suited for applications that require strong consistency and data integrity, such as financial systems or e-commerce platforms.

• MongoDB, on the other hand, does not support transactions in the same way as SQL databases, which means that data consistency may be more challenging to achieve.

‍

2. Data schemas:

• MongoDB is a schema-less database that does not require users to define a fixed schema upfront. This makes storing and querying data of different structures easy but can also make it more challenging to work with for some users.

• On the other hand, SQL databases use a fixed schema, meaning that data must be organised into tables with defined columns and data types. This makes it easier to work with structured data, but it can be more difficult to store and query data of different structures.

‍

3. Indexing:

• MongoDB and SQL databases support indexing, which can help speed up data access and improve the system's performance. However, the way that indexing works can be different between the two technologies. MongoDB supports various indexing options, including text search and geospatial indexing.

• While SQL databases typically support a more limited set of indexing options.

‍

4. Data storage

• MongoDB stores data in BSON format, a binary representation of JSON documents. This allows it to store data more efficiently than other NoSQL databases, but it can also make it more difficult to work with for some users.

• On the other hand, SQL databases store data in a structured, tabular format, which is easy to work with but may not be as efficient as BSON.

MongoDB vs SQL Server: Key differences

‍

‍

MongoDB and SQL Server are both popular database technologies, but they have many key differences that make them better suited for different types of applications. Understanding these differences is essential when deciding which technology to use for a particular project. Some main differences between MongoDB and SQL Server include the data model, data storage, schema, indexing, transactions, scalability, cloud support, ease of management, security, and data solutions. In this section, we'll take a closer look at these differences and explore how they can impact how applications are developed and maintained.

‍

1) Developed by and Initial Release

MongoDB was created by a company called 10gen (now known as MongoDB Inc.) and was initially released in 2007. It was designed as a more flexible and scalable alternative to traditional SQL databases, which became increasingly difficult to work with as data sets grew more extensive and complex. On the other hand, Microsoft developed SQL Server and had a much longer history. The first version of SQL Server was released in 1989, and it has since become a widely used database management system for various applications and industries. Despite the differences in their histories, MongoDB and SQL Server have become popular for developers building modern applications. While MongoDB is often chosen for its flexibility and scalability, SQL Server is still famous for its strong support for transactions and structured data.

‍

2) Database Model

MongoDB and SQL Server use different database models, which can impact how data is stored and accessed in the two technologies. MongoDB is a NoSQL database that uses a document-oriented data model. This means that data is stored in flexible, JSON-like documents containing any number of fields and having different structures. These documents are stored in collections, similar to SQL database tables. On the other hand, SQL Server uses a structured, tabular data model. This means that data is organised into tables, with each table containing a set of rows and columns.

‍

Each column in a table has a defined data type and can only contain data of that type. This makes it easy to work with structured data, but it can be more difficult to store and query data of different structures. The database model used by MongoDB and SQL Server can have a significant impact on the way that applications are developed and maintained. MongoDB is more flexible and can handle unstructured data, but it may be more difficult to work with for some users. SQL Server is more structured and easier to work with, but it may not be as flexible or scalable as MongoDB.

‍

3) Implementation Language

MongoDB and SQL Server are implemented in different programming languages. MongoDB is written in JavaScript, Python, Java, PHP, C++, C, Ruby, Perl, C, and C++, a high-performance programming language well-suited for building complex, high-performance systems. C++ is known for its speed and efficiency, making it a good choice for database systems that handle large amounts of data and high traffic levels.

‍

On the other hand, SQL Server is implemented in various languages, including C++, C#, and Transact-SQL (T-SQL). C++ is used for the core database engine, while C# is used for the graphical user interface and other management tools. T-SQL is a proprietary programming language that defines database objects and writes queries against the database. The implementation language of a database system can impact its performance, efficiency, and ease of use, but it is just one factor to consider when choosing a database technology. Other factors, such as the data model, data storage, schema, and indexing, can also be important considerations.

‍

4) License

MongoDB and SQL Server have different licenses, impacting how they can be used and distributed. MongoDB is available under the Server Side Public License (SSPL), a variant of the GNU Affero General Public License (AGPL). The SSPL is a copyleft license, which means that users are free to use, modify, and distribute the software as long as they make the source code available to others and do not use the software to provide a service to third parties.

‍

SQL Server is available under various licenses, depending on the edition and the specific use case. Some editions of SQL Server, such as the Express and Developer editions, are free, while others, such as the Standard and Enterprise editions, are only available for a fee. SQL Server is also available as a cloud service, which can be purchased on a pay-as-you-go basis. A database system's license can impact how it can be used and distributed, and it is essential to consider this factor when choosing a database technology.

‍

5) Data Schema

MongoDB is a schema-less database that does not require users to define a fixed schema upfront. This makes storing and querying data of different structures easy but can also make it more difficult to work with for some users. Because MongoDB does not have a fixed schema, storing documents with various structures in the same collection is possible.

‍

On the other hand, SQL Server uses a fixed schema, meaning that data must be organised into tables with defined columns and data types. This makes it easier to work with structured data, but it can be more difficult to store and query data of different structures. In SQL Server, each table must have a defined schema, and data can only be inserted into a table if it conforms to the schema. The data schema of a database system can impact the way that data is stored and accessed, and it is important to consider this factor when choosing a database technology. 

‍

6) Query Language

MongoDB uses the MongoDB Query Language (MQL), a powerful, expressive language specifically designed for working with the document-oriented data model of MongoDB. My SQL is based on the syntax of JavaScript, and it supports a wide range of operations, including data insertion, data retrieval, data updates, and data deletions. SQL Server uses Structured Query Language (SQL), a widely-used, standard language for accessing and manipulating data in relational database systems.

‍

SQL is a powerful language that supports many operations, including data insertion, retrieval, updates, and deleting data. Many database systems use SQL, so it is a good choice for developers who need to work with multiple database technologies. A database system's query language can impact how data is accessed and manipulated, and it is essential to consider this factor when choosing a database technology. MQL and SQL are powerful languages that support a wide range of operations but are designed for different data models. They may be more or less suitable for different types of applications.

‍

7) Scalability

MongoDB is designed to scale horizontally across multiple servers, which means it can handle a large volume of data and a high level of traffic by adding more servers to the system. It is a good choice for applications that need to scale quickly and efficiently. SQL Servers can also scale horizontally, but it is typically more efficient to scale vertically by adding more resources (such as memory or CPU) to a single server. In some cases, SQL Server may not scale as quickly or efficiently as MongoDB.

‍

However, SQL Servers can also scale horizontally, which makes it a good choice for applications that need to scale out across multiple servers. The scalability of a database system can impact the way that applications are built and maintained, and it is crucial to consider this factor when choosing a database technology. MongoDB is generally more scalable than SQL Server, but SQL Server can also scale horizontally in some cases.

‍

8) Map Reduce

MongoDB supports MapReduce, which means developers can use it to perform complex data processing and analysis tasks on large data sets. MapReduce is implemented in MQL, the MongoDB Query Language, and it allows developers to define a map function that processes input data and a reduce function that aggregates the results. MapReduce can be used to perform a wide range of tasks, including data filtering, data aggregation, and data transformation. SQL Server does not support MapReduce directly, but it provides several features that can be used to perform similar tasks.

‍

‍For example, SQL Server includes support for stored procedures, which can be used to define complex data processing logic that can be executed on the server. SQL Server also supports functions, views, and other database objects that can be used to manipulate data. The MapReduce capabilities of a database system can impact how developers perform complex data processing tasks, and it is essential to consider this factor when choosing a database technology. MongoDB provides support for MapReduce out of the box, while SQL Server offers other features that can perform similar tasks.

‍

9) Joins

MongoDB does not support traditional SQL-style joins, so developers must use other techniques to combine data from multiple collections. One common approach is to use the $lookup operator in the aggregation pipeline, which allows developers to perform a left outer join between two collections. Another approach is to denormalise the data and store it in a single collection, making it easier to work with but may not be as efficient for larger data sets. On the other hand, SQL Server supports a wide range of join types, including inner, outer, cross, and self-joins.

‍

Joins in SQL Server combine data from multiple tables based on a common key or set of keys. They can perform various tasks, including data filtering, data aggregation, and data transformation. The join capabilities of a database system can impact how data is combined and accessed, and it is important to consider this factor when choosing a database technology. MongoDB does not support traditional SQL-style joins, while SQL Server supports a wide range of join types.

‍

10) Transaction

MongoDB supports transactions only at the document level. This means that transactions in MongoDB can only be used to manage the state of a single document and cannot be used to manage multiple documents or collections. Transactions in MongoDB are implemented using the two-phase commit protocol, which ensures that a transaction is either fully committed or fully rolled back, depending on the outcome. SQL Server supports full transactions, which means that transactions can be used to manage the state of multiple tables, rows, or columns. Transactions in SQL Server are implemented using the ACID (atomicity, consistency, isolation, durability) model, ensuring that transactions are processed consistently and reasonably.

‍

Transactions in SQL Server can be used to manage complex data operations, such as data inserts, updates, and deletions. They can be used to ensure the integrity and consistency of data in the database. A database system's transaction capabilities can impact how data is managed and accessed, and it is crucial to consider this factor when choosing a database technology. MongoDB has limited support for transactions, while SQL Server supports full transactions. The XML support of a database system can impact the way that developers can work with XML data, and it is essential to consider this factor when choosing a database technology.

‍

11) XML Support

MongoDB does not have native support for XML, so developers must use other techniques to store and query XML data in the database. One common approach is storing XML data as a string or binary data type, then using MQL, the MongoDB Query Language, to query and manipulate the data. Another approach is to use the $regex operator to search for specific elements or attributes within the XML data.

‍

SQL Server, on the other hand, has native support for XML, which means that developers can use SQL to store, query, and manipulate XML data in the database. SQL Server includes several XML-specific functions and operators that can be used to extract, modify, and transform XML data. It also supports using XML indexes to improve the performance of XML queries.

‍
