Linux, the emerging operating system, is changing our lives. it is no longer a toy of early hackers and is entering various fields, from the high-end server market, to the low-end desktop market, as well as the emerging embedded operating systems, Linux has a complete impact. at present, Linux is the most successful in the server market. IDC survey last year showed that Linux has occupied 25% of the server market shipments, ranking second after NT. the growth rate is as high as 212%. the speed was surprising. linux is expected to play an increasing role in enterprise computing.
　　
This article will introduce the current situation and prospects of Linux in the enterprise computing field from a technical perspective. the application of Linux in enterprise computing mainly includes the following aspects:
　　
I. Business Applications
　　
1. Database
　　
It is not realistic to discuss in detail all the databases that support Linux, but for users, when selecting a database, you must first list the features and functions you need, then you can make a selection based on your needs. commercial databases are one of the first software to enter the Linux platform. including:
　　
(1 ). IBM DB2 (http://www.software.ibm.com/data/db2/linux/) IBM Universal Database is the flagship Database, including a variety of powerful features, its Linux version includes Web Control Center, a graphical Database management tool and Web programming interface.
(2 ). oracle (http://www.oracle.com/iplatform/linux/) Oracle currently supports Linux Oralce 8i (Oracle 8.1.5), including Oracle Application Server, Jserver, WebDB. for Linux users, the huge market share and superior performance of Oracle are a factor worth considering.
(3). Informix (http://www.informix.com/informix/products/linux/) Informix Linux versions include Informix SE, ESQL/C, Connect. its market target is a low maintenance cost, easy to manage database.

(5). Ingres (http://www.cai.com/products/betas/ingres_linux/ingresii_qa.htm) CA's Ingres II database.
　　
In the Opensource field, there are also a large number of SQL databases to choose from:
(1) InterBase (http://www.interbase2000.org/) InterBase is a commercial-level database of Inprise Opensource.
(2) MySQL (http://www.mysql.com) Mysql is the most widely used Free SQL Database, its features are simple and easy to use, fast. The disadvantage is that it does not support large capacity data, and does not support hot replication.
(3) PostgreSQL (http://www.postgresql.org/) PostgreSQL is second only to Mysql Free SQL Database, supports hot backup and ODBC. other Free Database also has Gadfly, BeagleSQL, Berkely DB, gnu SQL, gdbm and so on.
　　
2. Office software
　　
Currently, there are many types of Office software on Linux. from the commercial version to the OpenSource version, there are dozens of large and small versions. since Office software is a heavyweight software for Linux to enter the desktop market. at present, many companies are attaching great importance to this, among which Sun, Corel, and Applix are the most prominent companies.
　　
1. commercial Office software
　　
(1) Sun Staroffice (http://www.sun.com/products/staroffice/) Staroffice is one of the most functional Office software on Linux. sun plans to upgrade Staroffice to an international version that supports multiple languages, and open source code.
(2) Corel Wordperfect (http://linux.corel.com/products/wpo2000_linux/index.htm) Wordperfect is one of the participants of the last Office War, is also the earliest support for Linux Office software. However, currently, only Spanish is supported.
(3) Applixware of Applixware (http://www.applix.com/applixware/linux/) Applix is famous for its simple and practical functions and fast running speed. Currently, Applixware has a Japanese version. The Chinese version is planned to be released.
(4) Hancom's Wenjie word processing software (http://www.hancom.com/chinese/) Hancom's Wenjie is a 70% proportion of word processing software in the Korean market, it is also the first Chinese text processing software released on Linux. It is characterized by the use of WINE to port the Windows version, the operation speed is fast. Other commercial Office software includes Winz, XessLite, NExs, XQuad, and SmartWare.
　　
2. Opensource Office software
　　
(1) Koffice software (http://koffice.kde.org) under the KDE plan includes a full range of Office software, such as word processing, workbooks, demos and workgroup management, which features the use of the object-oriented technology of CORBA, the internal integration capability is relatively good. Based on QT2.0, Unicode is fully supported and is still under development.
(2) Lyx (http://www.lyx.org) Lyx is based on Latex what you see is the word processing software, but is more focused on the technical staff typographical science papers used. It is difficult for common users to use. At present, the simplified Chinese version of TurboLinux contains the Chinese version.
(3) Abiword (http://www.abisource.com/) Abiword is a relatively simple word processing software, currently only supports Spanish. The Gnome organization plans to use Abiword as part of its office software. Other Opensource office software include Ted and Siag Office.
　　
3. e-commerce software
　　
E-commerce is currently the focus of the most popular, and there are not many Linux-based e-commerce software. generally, because of the good compatibility between Linux and traditional UNIX. Similar software on other UNIX operating systems can be easily transplanted to Linux. Currently, Linux-based e-commerce products include:
　　
1 ). akopia's e-commerce system Tallyman (http://www.akopia.com) Tallyman is a highly customizable e-commerce development system that includes easy-to-use Web-based system management tools and e-trading tools, such as product management tools and shopping cart. It is easy to use and grasp. It is more oriented to beginners with low technical levels.
2). IBM's Websphere (http://www-4.ibm.com/software/webservers/) WebSphere is IBM according to the current development trends of Internet and e-commerce, launched a set of functional network environment development and application software packages. This includes creating webpages, setting up and maintaining websites, developing e-commerce applications, and effectively managing your own data. Establish Online dynamic publishing, Data Query, feedback, and other e-commerce requirements for enterprises, products, and services to achieve online enterprises. In addition, it can easily connect with existing enterprise systems to achieve information sharing and convenient management. The advantage of Websphere is that it includes its own Java development tool visual age, its own Application Server, and so on, which gives users a comprehensive package of solutions. In terms of technical support, we can also get a good return.

Including the Optimization Components, visualized Components, and Business Rules Components ). OpenSource's e-commerce software currently has openmerchant (http://www.opensales.org/) and so on.
　　
II. network applications
　　
Linux, as a network operating system, plays a more significant role in the network. This is also an important part of Linux's entry into enterprise-level computing.
　　
1. network management/graphical system management
　　
(1). VNC (http://www.uk.research.att.com/vnc/) is a graphical interface that allows users to remotely use his NT/Macintosh/UNIX, similar to PC Anywhere, is a good management tool within the LAN.
(2) Linuxconf (http://www.solucorp.qc.ca/linuxconf/) is the most widely used configuration tool on Linux, including text, graphics, Web three interfaces, and can be extended by writing plug-ins.
(3) Webmin (http://www.webmin.com/) is a pure web interface system management tool, which can not only manage Linux, but also manage other UNIX. webmin is written in Perl. it supports SSL encryption and complies with the BSD copyright.
(4) SNMP Network management tools in Linux use SNMP to manage network servers. Currently, SNMP tools in Linux are classified into system management tools and SNMP tools,
　　
System management tools include:
　　
* Mon (http://consult.ml.org /~ Trockij/mon/) system monitoring tool
* PIKT (http://pikt.uchicago.edu/pikt/) fault monitoring tool
* Scotty (http://www.cs.utwente.nl /~ Schenw/scotty/) network management tool
* Big Brother (http://www.iti.qc.ca/iti/users/sean/bb-dnld/) system monitoring tool
　　
SNMP tools include:
　　
* MRTG (http://www.ee.ethz.ch /~ Oetiker/webtools/mrtg/mrtg.html) network traffic monitoring tool
* Cmu-snmp (http://www.gaertner.de/snmp/) SNMP tool
　　
2. Lan-related technologies
　　
LAN technology mainly refers to Linux's compatibility with existing LAN networks. Currently, the LAN mainly includes NT/Win95 SMB/LAN Manager, Novell Netware, and Macintosh Appletalk networks. However, Linux has good compatibility with these networks and can replace all these network servers with one Linux server, which is unknown to users.
　　
　　
* SAMBA server (http://www.samba.org) compatible with NT/Win95 networks: Samba is a software package on Linux, linux supports SMB protocols widely used in windows, such as OS/2, windowsNT, windows95, and windows for workgroups. this protocol is mainly used for file and printer sharing. This allows Linux to provide the file printing and sharing service as a virtual server. and shared with Unix files. samba can also do some work that usually requires the windowsNT server, such as providing the WINS Service or providing the login NT Domain Service for the windows95 client.
　　
* Compatible with Netware network Mars_nwe/lwared. There are two Netware File print sharing services available in Linux, the widely used is the mars_nwe (ftp://ftp.gwdg.de/pub/linux/misc/ncpfs/mars_nwe-0.99.pl18.tgz) package, the other is called lwared (ftp://klokan.sh.cvut.cz/pub/linux/linware ), only the file sharing service can be provided, and the printing and sharing service cannot be provided, while mars_nwe can provide both printing and file sharing services .. mars_nwe implements a subset of Novell NCP.
　　
* Netatalk compatible with the Atalk protocol (http://www.umich.edu /~ Rsug/netatalk /)
