SQLite是一个轻量型的数据库,各方面由于Access,对于小型网站来说,非常适合!我今天决定将系统的数据库由Access转换为SQLite。 在网上搜索了一下,找到了DBManager这个工具,不得不说,这个软件确实好,很强大,在网上找注册码也找到半天,找不到一个!
只要将Access转换为SQLite,然后使用System.Data.SQLite.dll来访问数据库。我们用DbManager创建一个SQLite数据库。
如下图:
2.选择数据,并点击工具 - 数据管理 - 导入数据
3.按照向导,选择Access,mdb文件,并选择文件位置后将会列出Access数据库的所有表。选择所有表,并包括数据
4.点击确认开始导入数据,导入完成后,打开表发现跟原来的数据完全一致!
数据库导入的工作已经完成了,我们可以将这个SQLite数据库用到我们的项目中!
可惜的是,读取SQLite时候,给报一个错:
File opened that is not a database file
file is encrypted or is not a database
用SQLiteSpy打开SQLite数据库时候提示输入密码。
我就为这个问题,弄了一下午时间,网上说数据库损坏了,也有的说在连接字符串设置密码。
经过反复的思考之后,觉得问题应该出在SQLite的版本上,只能通过其他方式来将Access转为SQLite了。
还好,数据库都支持SQL,我只有设法将数据导出为SQL文件,然后通过SQLiteSpy创建一个支持ASP.Net调用的文件。在这个文件中执行脚本!
结果终于搞定!
DBManager也支持SQLite数据导出为SQL文件:选择数据库->Dump,按照向导出脚本
脚本导出之后,我们就可以使用SQLiteSpy创建新的数据库了:File->New DataBase
创建完成之后,执行刚才保存的SQL脚本。
现在,可以将这个数据库文件放到我们的项目中供System.Data.SQLite.dll 调用了!

Apache server is a powerful web server software that acts as a bridge between browsers and website servers. 1. It handles HTTP requests and returns web page content based on requests; 2. Modular design allows extended functions, such as support for SSL encryption and dynamic web pages; 3. Configuration files (such as virtual host configurations) need to be carefully set to avoid security vulnerabilities, and optimize performance parameters, such as thread count and timeout time, in order to build high-performance and secure web applications.

Oracle is not only a database company, but also a leader in cloud computing and ERP systems. 1. Oracle provides comprehensive solutions from database to cloud services and ERP systems. 2. OracleCloud challenges AWS and Azure, providing IaaS, PaaS and SaaS services. 3. Oracle's ERP systems such as E-BusinessSuite and FusionApplications help enterprises optimize operations.

This article will explain how to improve website performance by analyzing Apache logs under the Debian system. 1. Log Analysis Basics Apache log records the detailed information of all HTTP requests, including IP address, timestamp, request URL, HTTP method and response code. In Debian systems, these logs are usually located in the /var/log/apache2/access.log and /var/log/apache2/error.log directories. Understanding the log structure is the first step in effective analysis. 2. Log analysis tool You can use a variety of tools to analyze Apache logs: Command line tools: grep, awk, sed and other command line tools.

Nginx performance monitoring and troubleshooting are mainly carried out through the following steps: 1. Use nginx-V to view version information, and enable the stub_status module to monitor the number of active connections, requests and cache hit rate; 2. Use top command to monitor system resource occupation, iostat and vmstat monitor disk I/O and memory usage respectively; 3. Use tcpdump to capture packets to analyze network traffic and troubleshoot network connection problems; 4. Properly configure the number of worker processes to avoid insufficient concurrent processing capabilities or excessive process context switching overhead; 5. Correctly configure Nginx cache to avoid improper cache size settings; 6. By analyzing Nginx logs, such as using awk and grep commands or ELK

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

The Nginx current limit problem can be solved by: use ngx_http_limit_req_module to limit the number of requests; use ngx_http_limit_conn_module to limit the number of connections; use third-party modules (ngx_http_limit_connections_module, ngx_http_limit_rate_module, ngx_http_access_module) to implement more current limit policies; use cloud services (Cloudflare, Google Cloud Rate Limiting, AWS WAF) to DD
