MongoDB supports a variety of data types, including numeric types (Double, Int, Long, Decimal128), string types (String, ObjectId), Boolean types (Bool), date and time types (Date, Timestamp) , binary types (Binary), other types (Null, Array, Object), and extended JSON data types (Regex, JavaScript, Symbol).
MongoDB data types
MongoDB is a document database that supports rich data types, to store data of various formats and properties. These types include:
Numeric types:
- Double: 64-bit floating point number used to store decimals and very large numbers .
- Int: 32-bit signed integer used to store integers.
- Long: A 64-bit signed integer used to store very large integers.
- Decimal128: A 128-bit decimal floating point number used to store precise decimals.
String type:
- String: UTF-8 encoded Unicode string used to store text and symbol.
- ObjectId: A 12-byte unique identifier that uniquely identifies the document.
Boolean type:
- Bool: Boolean value, used to represent true or false.
Date and time types:
- Date: Representation of date and time in milliseconds since the epoch (UNIX epoch ) since storage.
- Timestamp: A 64-bit date and timestamp, where the first 32 bits are seconds and the last 32 bits are nanoseconds.
Binary type:
- Binary: Arbitrary sequence of bytes, used to store images, files, and binary data.
Other types:
- Null: Indicates that the value does not exist.
- Array: An ordered collection of elements. The elements can be of any data type.
- Object: A set of key-value pairs, where the key is a string and the value can be any data type.
Extended JSON Data Types:
- Regex: Regular expression, used for Match text pattern.
- JavaScript: A special type that can store and execute JavaScript code.
- Symbol: Similar to string, but with stricter syntax rules.

MongoDB is suitable for handling large-scale unstructured data, and Oracle is suitable for enterprise-level applications that require transaction consistency. 1.MongoDB provides flexibility and high performance, suitable for processing user behavior data. 2. Oracle is known for its stability and powerful functions and is suitable for financial systems. 3.MongoDB uses document models, and Oracle uses relational models. 4.MongoDB is suitable for social media applications, while Oracle is suitable for enterprise-level applications.

MongoDB's scalability and performance considerations include horizontal scaling, vertical scaling, and performance optimization. 1. Horizontal expansion is achieved through sharding technology to improve system capacity. 2. Vertical expansion improves performance by increasing hardware resources. 3. Performance optimization is achieved through rational design of indexes and optimized query strategies.

MongoDB is a NoSQL database because of its flexibility and scalability are very important in modern data management. It uses document storage, is suitable for processing large-scale, variable data, and provides powerful query and indexing capabilities.

You can use the following methods to delete documents in MongoDB: 1. The $in operator specifies the list of documents to be deleted; 2. The regular expression matches documents that meet the criteria; 3. The $exists operator deletes documents with the specified fields; 4. The find() and remove() methods first get and then delete the document. Please note that these operations cannot use transactions and may delete all matching documents, so be careful when using them.

To set up a MongoDB database, you can use the command line (use and db.createCollection()) or the mongo shell (mongo, use and db.createCollection()). Other setting options include viewing database (show dbs), viewing collections (show collections), deleting database (db.dropDatabase()), deleting collections (db.<collection_name>.drop()), inserting documents (db.<collecti

Deploying a MongoDB cluster is divided into five steps: deploying the primary node, deploying the secondary node, adding the secondary node, configuring replication, and verifying the cluster. Including installing MongoDB software, creating data directories, starting MongoDB instances, initializing replication sets, adding secondary nodes, enabling replica set features, configuring voting rights, and verifying cluster status and data replication.

MongoDB is widely used in the following scenarios: Document storage: manages structured and unstructured data such as user information, content, product catalogs, etc. Real-time analysis: Quickly query and analyze real-time data such as logs, monitoring dashboard displays, etc. Social Media: Manage user relationship maps, activity streams, and messaging. Internet of Things: Process massive time series data such as device monitoring, data collection and remote management. Mobile applications: As a backend database, synchronize mobile device data, provide offline storage, etc. Other areas: diversified scenarios such as e-commerce, healthcare, financial services and game development.

How to view MongoDB version: Command line: Use the db.version() command. Programming language driver: Python: print(client.server_info()["version"])Node.js: db.command({ version: 1 }, (err, result) => { console.log(result.version); });

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
