          <b><span style="font-size:12px;">权威指南》</span></b><span style="font-size:12px;">之后第三本由中国人原创的图数据库专业书籍。</span><span style="font-size:12px;"></span></b></b></p>
<p style="margin-bottom:18px;font-stretch:normal;font-size:18px;line-height:normal;font-family:&quot;color:#343434;">
          <b style="font-size:12px;font-family:&quot;color:#000000;"><span style="font-size:12px;"><span style="font-size:12px;">图数据库的发展日新月异，短短三年时间，国内外涌现出多款图数据库系统，然而在DBEngine排名中，Neo4j依然稳居第一。本书将陪</span><span style="font-size:12px;">伴你漫步“图”的世界，领略“图”的风采，玩转大数据时代新的利器——图数据库Neo4j。</span></span></b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b><span style="font-size:12px;">“图数据库”即便对业内人士而言，也是一个陌生的词汇。单这个“图”字，便会使人联想到图形、图片或图像。 那么，图数据库究竟是什么？优势在哪儿？可以用它来干什么？</span></b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b><span style="font-size:12px;">图数据库是一个新型的数据库系统。大家以前可能听到过MySQL、Oracle等数据库，但随着社交、金融、零售等行业的发展，亟需一种新型的数据库来支撑这些新的业务。现实社会织起了一个庞大而复杂的关系网，比如天天有人给你打电话要你买房子，他们是通过什么技术来找到你的呢？就是通过一些关系运算。如果使用传统的数据库会很难处理，而采用图数据库来处理它，会更高效、更方便。在科技领域里有一个六度空间理论，简单地说，就是世界上任何两个人最多只需通过6个关系就一定能够找到对方。用图数据库就可以把这个理论变成现实。所以，称它为一种新型的数据库完全不为过，它能支持海量、复杂、多变数据的关系运算，而且运算性能非常高。</span></b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b><br /></b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:14px;line-height:normal;font-family:&quot;color:#118DFF;"><span style="color:#337FE5;"><strong>和传统数据库比起来，图数据库的优势在哪儿呢？</strong></span></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:14px;line-height:normal;font-family:&quot;color:#118DFF;"><br /></p>
        <p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b>首先，图数据库可以说是应专门处理这种复杂关系网的“运”而生的。虽然传统的数据库也能处理，但其效率极其低下，功能扩展也很困难，要花的时间将很长，而用图数据库就能方便、高效地解决这个问题；更重要的是，就连非技术人员都能看得懂。如果用传统数据库来构建，其模型非常复杂、烦琐，相比而言，用图数据库，就非常直观、浅显、简单。</b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b>图数据库的应用领域非常广，在社交、零售、金融等领域都有广泛的应用案例。比如说社交，一个最典型的应用就是领英。领英在国际上的知名度和应用的广度相当于我们中国的微信。领英一个最重要的功能就是能够把你朋友的朋友的朋友推荐给你，这是进行了关系运算的结果。另外一个就是零售商品的实时推荐，比如沃尔玛，你在它的网站上点击了几个商品后，它就能揣测出你可能对哪些商品感兴趣，就会立马把你感兴趣的商品推荐给你。用图数据库来计算这种推荐会更快捷。现在国外用得很多，但是在我们国内才刚刚开始。随着图数据库的应用，不久的将来我们就可以享受到更为实时、准确、方便的推荐。</b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b>总之，图数据库能高效地处理各种复杂的关系网络，在许多领域有着广泛的应用。它是基于图论而实现的新型数据库系统，擅长处理大量的、复杂的、互联的、多变的网状数据，其效率远远高于传统的关系数据库。</b></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">
          <b>现在在世界上很多著名的公司都在使用图数据库。比如，领英用它来管理社交关系，实现朋友推荐，构建了一个非常强大的人脉网络；沃尔玛用它连接“商品关联”和“买家习惯”两个子网，实现了零售商品的实时推荐，给买家带来更好的购物体验；思科用它做主数据管理，将企业内部的组织架构、产品订购、社交网络、IT网络等有效地管理起来；惠普用它管理复杂的IT网络；全球财富100强的前75家公司都在用图数据库，用户涵盖了物流、交通、电信、制造业、广告、打印、文化传媒和医疗等各个领域和行业。我们2015年开始研究图数据库，当时国内知道图数据库的人还寥寥无几。令人意想不到的是，才短短7年多时间，国内竟然有很多领域都用上了图数据库，涉及的领域包括金融、社交、智能制造、物流、医药等。毋庸置疑，其发展速度将远超我们的想象。 然而遗憾的是，目前市面上有关图数据库的中文书籍屈指可数，即便有也是直接从英文原版翻译而成。随着图数据库在中国的推广和普及，大家都渴求有一本国人原创的权威指南，能系统、全面地涵盖图数据库的原理和使用方法等方方面面内容。因此，我们决定集中组织国内对图数据库有深入研究的专家，共同编写一套原创的中文版图数据库技术丛书。</b></p>

<h3><span style="color:inherit;font-size:16px;font-weight:700;">将数据库标记为“只读”</span></h3>
<p><span style>用户及应用程序可在维护工作中继续使用读取服务。</span></p>
<p><span style>现在可以将某个数据库标记为“只读”，以便在维护期间可以让用户和应用程序仍保持可访问状态。 例如，用户可以在制作数据库碎片整理副本的同时继续生成报告。</span></p>
<p>

<h3><span style="color:inherit;font-size:16px;font-weight:700;">用户模拟</span></h3>
<p><span style="font-size:12px;">确保图数据库应用程序被安全地部署和使用。</span></p>
<p><span style="font-size:12px;">添加用户模拟可以更轻松地更快地设计和开发图数据库应用程序。 微服务和n层应用程序可以应用“最低权限”安全最佳实践。 这通过在现有连接的上下文中模拟不同的用户来减少创建新连接的消耗。</span></p>

      <title>Apache Log4j2 安全隐患提示！！！</title>
      <description><![CDATA[  <p><strong style="font-family:&quot;color:#000000;font-size:16px;">各位亲爱的图粉大家好：</strong></p>
<p><br /></p>
        <p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">本周周末爆发出的Apache Log4j2漏洞对市面上广大服务、软件都带来了巨大的隐患，我们也在第一时间就此和Neo4j原厂进行了沟通。 根据Neo4j官方的反馈，现提供了以下解决方案。</p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><span style="font-family:&quot;font-size:13px;"> </span></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><br /></p>
        <p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><span style="font-size:16px;"><strong>受到影响</strong></span>的Neo4j版本包括（使用log4j2）：</p>
<ul>
  
          <li style="margin:0px 0px 8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><strong>Neo4j 4.2及4.2之后推出的所有版本</strong></li>
</ul>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">关于Neo4j 4.2版本开始使用log4j2说明：</p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#56C1FF;"><a href="https://github.com/neo4j/neo4j/blob/4.2/pom.xml#L140">https://github.com/neo4j/neo4j/blob/4.2/pom.xml#L140</a></p>

        <p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><span style="font-size:16px;"><strong>未受影响</strong></span>的Neo4j版本包括（使用slf4j-log4j12）：</p>
<ul>

        <p style="margin-bottom:8px;font-stretch:normal;font-size:16px;line-height:normal;font-family:&quot;color:#000000;"><strong>解决方案：</strong></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">对于已部署Neo4j 4.2及以上版本的用户，可以通过设置以下参数来解决（conf/neo4j.conf）：</p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><span style="background-color:#FFE500;">dbms.jvm.additional=-Dlog4j2.formatMsgNoLookups=true</span></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;"><span style="background-color:#FFE500;">dbms.jvm.additional=-Dlog4j2.disable.jmx=true</span></p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">更改设置完成后，需要<strong><span style="font-size:16px;">重启</span></strong>服务。</p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;min-height:14.3px;"><br /></p>
        <p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">以上方案一样适用于Neo4j Desktop。</p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">Neo4j Sandbox及Neo4j AuraDB已通过升级解决，Docker镜像则已通过禁用jmx设置进行了更新。&nbsp;</p>
<p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;min-height:14.3px;"><br /></p>
        <p style="margin-bottom:8px;font-stretch:normal;font-size:12px;line-height:normal;font-family:&quot;color:#000000;">近期，Neo4j也将在下一个更新的版本中解决相关问题。&nbsp;</p>
