The MongoDB database file is located in the MongoDB data directory, which is /data/db by default, which contains .bson (document data), ns (collection information), journal (write operation record), wiredTiger (using Files such as WiredTiger storage engine data) and config (database configuration information).
#Where are the MongoDB database files?
Answer: The MongoDB database files are located in the MongoDB data directory, which is /data/db
by default.
Detailed explanation:
MongoDB stores its database files in a specific directory called the data directory. This directory contains the following files:
- #.bson files: These files store document data. Each collection has a separate .bson file.
- ns files: These files store information about each collection, such as the collection name, field indexes, and other metadata.
- journal files: These files are used to record writes made to the database.
- wiredTiger files: These files store data when using the WiredTiger storage engine.
- config files: These files store information about the database configuration, such as replica set settings.
Modify the data directory location:
By default, MongoDB uses /data/db
as the data directory, but you can pass it in Use the --dbpath
option when starting MongoDB to change this location. For example:
mongod --dbpath /my/custom/data/directory
Accessing database files:
MongoDB database files are generally not directly accessible. You must use the MongoDB shell or other client application to access and operate the database.

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); });

MongoDB provides a sorting mechanism to sort collections by specific fields, using the syntax db.collection.find().sort({ field: order }) ascending/descending order, supports compound sorting by multiple fields, and recommends creating indexes to improve sorting performance.

To connect to MongoDB with Navicat: Install Navicat and create a MongoDB connection; enter the server address in the host, enter the port number in the port, and enter the MongoDB authentication information in the user name and password; test the connection and save; Navicat will connect to the MongoDB server.

MongoDB provides a variety of document deletion methods: Delete a single document: Use the deleteOne() method to specify a query object. Delete multiple documents: Use the deleteMany() method to specify a query object. Delete the entire collection: Use the drop() method. Delete documents using index: Use the findOneAndDelete() method to specify a query object and return the deleted document. Delete embedded documents: Use the $unset update operator to set the embedded document field to null.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
