MongoDB and Node.js integrated development practice

MongoDB and Node.js integrated development practice

This article describes how to integrate Node.js and MongoDB using MongoDB drivers. 1. The MongoDB driver is a bridge connecting the two and provides API for database operations; 2. The code example shows connecting to the database, inserting and querying documents, and uses async/await and try... finally blocks; 3. In actual applications, pagination query, error handling, performance optimization (index, database structure design, batch operation) and code readability should be considered. Through these steps, flexible and high-performance applications can be efficiently built.

MongoDB Quick Start: From Installation to Basic Operations

MongoDB Quick Start: From Installation to Basic Operations

This article introduces the quick way to get started with MongoDB. 1. Install MongoDB: Download the corresponding version installation package and run the installer to start MongoDB service; 2. Basic operations: Use the PyMongo driver to perform CRUD operations (insert, query, update, delete), pay attention to connecting and closing the database; 3. Performance optimization: Reasonably design the database structure and select appropriate indexing strategies based on actual conditions to avoid excessive indexes. By mastering these steps, you can quickly get started with MongoDB.

What is the difference between Oracle and MySql

What is the difference between Oracle and MySql

Oracle and MySQL are two leading RDBMSs, Oracle is commercial software, and MySQL is open source software. Oracle adopts a multi-process architecture, with better performance, better scalability, but higher cost. MySQL adopts a multi-threaded architecture, which has higher cost performance and more flexible data types, but its high availability and security are not as good as Oracle. Therefore, Oracle is suitable for mission-critical enterprise applications, and MySQL is more suitable for small to medium-sized applications.

How to solve high concurrency with redis

How to solve high concurrency with redis

Redis efficiently solves high concurrency problems, mainly due to the following mechanisms: 1) memory storage, extremely fast read and write; 2) single-thread event loop, lock-free competition; 3) multiplex I/O, listening to multiple connections at the same time; 4) Optimize data structures, quickly find, insert and delete; 5) replication and clustering, load balancing and fault tolerance; 6) persistence to ensure data security.

What to do if the SQL database is too big

What to do if the SQL database is too big

In response to the problem of excessive SQL database size, solutions include: partition tables, dividing large tables into smaller partitions; archive data, moving infrequently accessed data to other tables or databases; compressing, using algorithms to reduce data size; data cleaning, deleting duplicates, invalid records or historical data; vertical partitioning, splitting wide tables into vertical partitions containing specific columns; table decomposition, decomposing logical tables into entity tables; external data sources, storing certain data in cloud storage or NoSQL databases; vertical scaling, increasing server resources; horizontal partitioning, distributing data to multiple servers or nodes;

How to optimize sql query slow

How to optimize sql query slow

Slowly running SQL query optimization strategy: Determine query bottlenecks: Use the EXPLAIN or EXPLAIN ANALYZE statement. Create an appropriate index: Create an index for frequently used columns. Optimize table joins: Use HASH or MERGE JOIN to explicitly specify the connection conditions. Rewrite subquery: Use the connection or EXISTS/NOT EXISTS condition. Optimized sorting and grouping: Use column sorting or grouping of indexes. Utilize query cache: Stores executed query plans. Adjust database configuration: optimize parameters such as memory allocation. Hardware upgrade: Consider adding memory or replacing CPU.
