    在上一期,我们聊到了如何搭建一个企业面向外部的信息沟通渠道。在这个交流平台搭建好之后,一般情况下有关企业产品、新闻、服务等信息都能够方便快捷的传递到客户层面,产生销售机会,并加快反馈信息的收集速度。然而,对外的渠道畅通之后,我们怎样才能将蜂拥而来的各类信息加以甄别筛选,使企业的决策更加快速准确,使业务反映更加灵活高效呢?显然,我们需要一套系统来梳理我们的业务流程,增加我们的业务灵活性,整合业务的方方面面资源,以达到勤练内功,提升效能的目的。

    为了提升企业运作效率,我们需要整合企业管理理念、业务流程、基础数据、人力物力、计算机硬件和软件管理体系于一体的企业资源管理系统。ERP(Enterprise Resources Planning,“企业资源计划”),是在MRPII(Manufacturing Resources Planning,“制造资源计划”)基础上进一步发展而成的面向供应链(Supply Chain)的管理思想,是综合应用了客户机/服务器体系、关系数据库结构、面向对象技术,以ERP管理思想为灵魂的软件产品;ERP系统一个非常突出的特点,就是管理信息的高度集成,这是ERP同手工管理的主要区别。管理信息集成的效果,决不是简单的数量叠加,而是管理水平和人员素质在质量上的飞跃。信息集成和规范化管理是相辅相成的,应当按照统一的程序和准则进行管理,既不因人而异,随心所欲,又要机动灵活,适应变化的环境。

    ERP系统由于涉及到供应链管理,访问ERP系统的用户会比较多,在一个大型的ERP系统中,同一时间访问ERP系统核心数据库的用户可能达到几百上千个,而中小企业一般只有几个到几十个。在ERP系统操作中,一般每个操作所耗资源量不大,主要为一些结构性数据的查询和分析。为此我们在本ERP系统中需要一个支持大并发,小数据流的高性能数据库服务器平台来承载ERP系统的应用。

    在服务器硬件方面,由于并发访问ERP系统的用户数较多,要求系统带宽不能成为整个应用的瓶颈,还要求系统具有极强的处理能力,及很高的并发性。在数据存储方面要求有巨大的磁盘空间和巨大的扩展性以及高速的数据传输标准以满足数据库的需求。

    作为ERP软件平台的载体,企业信息化需要选择优秀的硬件服务器系统平台。我们一般从这几方面来衡量其整体性能:

    ①.企业级计算性能
    企业ERP信息系统的工作内容大多是数据密集型操作,数据来源相当广泛,种类繁多,数据库和各类应用都面临着数据采集、数据集中、数据查询等数据密集型操作,同时还面临着OLAP(联机分析处理)和建立决策支持数据仓库的需要,因此,服务器系统强劲的CPU数据处理能力和扩展能力就十分重要。在中小企业应用中,一般选择2路Xeon处理器的服务器配备2GB大内存一般性能上够用,如果碰到规模更大一些的应用,就建议配置4路Xeon MP处理器的高性能服务器了。

    ②.高度的可靠性和可用性
    数据库和各类应用每天都面临着大量数据的收集和处理,服务器系统的冗余容错能力提供了高可靠性和可用性,再辅之高可用性方案设计,才可充分保证企业ERP信息系统工作的不间断进行。像服务器的冗余电源、内存镜像等设计都可以考虑。

    ③.极佳的稳定性
    作为企业ERP信息系统的支撑平台,需要保证服务器系统能持续、高效、稳定的运行,以减少对服务器系统的管理和维护的时间和工作量,以及计划外停机时间。稳定性依赖于软硬件的兼容性和各自的稳定性设计。

    ④.对数据的高保护性
    不言而喻,对于数据就是生命的企业ERP信息系统来讲,数据在服务器系统中进行计算、存储和网络传输时,其完整性、有效性是必须保证的。对于有机密要求的数据,还要保证数据的机密性。

    在ERP与数据库系统同时部署在一台机器上的小型系统可以将数据存储在本机上,如果ERP系统与数据库系统分离,则可在数据库服务器后挂载专用存储设备来存储数据,保证数据的安全。

    ⑤.良好的管理性
    在企业ERP信息系统中各种网络设备、计算机设备、安全设备种类繁多,这对整个系统的管理和控制提出了很大挑战。就服务器系统而言,专业服务器系统管理软件对服务器系统的集中和可视化管理,将使网络计算环境管理变得简单易行。

    ⑥.设备厂商良好的技术和服务队伍
    设备生产厂商强大的研发实力、过硬的生产工艺,获得ISO9000质量体系认证和ISO14000环境保护体系认证是保证设备拥有极佳品质、保证设备可靠性、稳定性的基础,而厂商优秀的研发、售前、售中及售后服务队伍更是企业信息化得以顺利实施和可靠运行的保证。

    ⑦.软硬件集成
    服务器系统与功能丰富,性能可靠,遵从工业标准,提供全方位企业级功能的操作系统的无缝集成能力,与专业数据库系统软件良好的一致性和可集成性,是满足服务器系统整体具有大范围的可伸缩性、极高的主机性能、长时间的系统运行能力,丰富多样的高性能业务解决方案,以及提供用于OLTP(联机事务处理)、OLAP(在线分析处理)、数据仓库、决策支持等诸多应用的数据集中功能。如果采用Oracle等大型数据库,可以要求服务器通过Oracle的OCE测试认证,以保证环境的兼容性。

    总之,通过ERP系统的建设,我们可以实现数据共享、文件共享,同时通过与外部的互连,达到信息收集、分析、处理,直至快速反应,提高应变能力的目的。纵观现在市面上许多主流服务器,浪潮NL230G2不仅能够满足这众多应用要求,并且从客户反馈的性能、价格、售后服务等方面来说,都是一款值得推荐作为ERP/数据库企业核心应用的可靠产品。

Explain the role of InnoDB redo logs and undo logs.Explain the role of InnoDB redo logs and undo logs.Apr 15, 2025 am 12:16 AM

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AM

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

What is the Using temporary status in EXPLAIN and how to avoid it?What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AM

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB

Describe the different SQL transaction isolation levels (Read Uncommitted, Read Committed, Repeatable Read, Serializable) and their implications in MySQL/InnoDB.Describe the different SQL transaction isolation levels (Read Uncommitted, Read Committed, Repeatable Read, Serializable) and their implications in MySQL/InnoDB.Apr 15, 2025 am 12:11 AM

MySQL/InnoDB supports four transaction isolation levels: ReadUncommitted, ReadCommitted, RepeatableRead and Serializable. 1.ReadUncommitted allows reading of uncommitted data, which may cause dirty reading. 2. ReadCommitted avoids dirty reading, but non-repeatable reading may occur. 3.RepeatableRead is the default level, avoiding dirty reading and non-repeatable reading, but phantom reading may occur. 4. Serializable avoids all concurrency problems but reduces concurrency. Choosing the appropriate isolation level requires balancing data consistency and performance requirements.

MySQL vs. Other Databases: Comparing the OptionsMySQL vs. Other Databases: Comparing the OptionsApr 15, 2025 am 12:08 AM

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.

How does MySQL index cardinality affect query performance?How does MySQL index cardinality affect query performance?Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
