Let’s Go where the PokemonGoes

Sachin Dabir

PokemonGo is no more a child’s play. There are over 21 million Daily Active Users just in the USA, claims surveymonkey. Within the first week of its launch, it continues to pull people of all age groups into it. And the downside is, it is pulling down the servers due to overload. It already has surpassed Twitter and Tinder in terms of number of users. And all these initial users numbers are coming from just few countries where PokemonGo has been released until now. Imagine […]

You are looking for a Database, not a Swiss knife!

Sameer_Ashnik

We keep having so many conversations with our customers, technology associates and regional partners across various geographies, and no discussion is really different. It commonly revolves around the need of different types of databases and the different data-models. For starters, an ISV vendor who is currently using a noSQL store to store unstructured data for events form sensors (in JSON format); wanted to know if that can actually be merged with relational data and stored together in a relational database. I […]

为你解答关于Oracle迁移的所有问题!

Sameer_Ashnik

在过去的几周中,我们收到了许多关于Oracle迁移和Oracle替换的相关问题!其中一些问题是特别针对从Oracle数据库迁移到性价比更高的数据库——Postgres Plus Advanced Server的,而有些问题则是关于替换他们数据中心的Oracle数据库的实施方案。 虽然我们总是收到一些客户关于显著降低其数据中心Oracle数据库或SQL Server数据库成本的请求,但是这一问题的井喷式出现着实让我们有点小惊讶,同时也有点小兴奋。我们发现客户在策略上的这一突然转变是因为他们对Oracle许可条款变化的推测。而我们认为另外一个诱导因素是客户需要在其Oracle许可证到期前做出提前规划。 我们拥有博客、视频和白皮书等形式的丰富资源,对于回答这些问题非常有帮助。正在考虑将这些资源整合成一个简明的目录,以方便那些想要维持成本并且丰富其数据中心关系型数据库管理系统(RDBMS)多样性的客户。 PostgreSQL本身是一种真正的关系型数据库,具备很多开发者友好特性。EnterpriseDB为了达到更好的性能和安全性,在PostgreSQL内核的基础上增加了对Oracle的兼容性,以及其他的一些特性,比如Dyna Tune、SQL保护、缓存预热等。 以一个数据库管理员(DBA)的角度来看,理解和掌握PostgreSQ和其他数据库完全一样。这主要是因为它和其他数据库都是在相同的关系基础上建立的。阅读我们中的一位来自Oracle数据库管理员团队的成员发布的文章“一名从Oracle到Postgres的DBA的历程” 如果你有任何关于Postgres Plus Advanced Server特性和扩展性的问题,可以关注一下How InMobi,它是最大的独立移动广告公司,借助EnterpriseDB可以实现每月数以亿计的广告曝光次数。 对于你们中那些想要从Oracle转移又存在高可用性和可靠性疑虑的人,请牢记PostgreSQL具备与其他数据库相似的极其稳健的可靠性。实际上,你可以在同一服务器或远程服务器上实现WAL文件的多路复用。从v9.0版本开始,以后所有的版本都内嵌了复制机制。很容易就能设置流式复制,可用于设置冗余以及实现很高的可用性。了解更多Postgres的高可用性和数据记录选项,可以访问我们的共享幻灯片。 说到HA(高可用性)和扩展性,Oracle用户经常被RAC陷入困境。RAC是实现高可用性的一种特殊方式。可以阅读我们的博客评估你是否真正需要RAC之类的方式来实现高可用性。借助Postgres 和 EnterpriseDB工具,有可能搭建一个规模可调且高度可用的数据库群。 对于你们中那些已经意识到需要从已有的SQL Server或Oracle设置中迁移出来的人,我们有一些很好的关于如何开始的建议可供参考。查看我们的博客“如何舍弃Oracle投入Postgres”和“消除从SQL Server 转移至 PostgreSQL的阵痛”。 关于PostgreSQL 和 EnterpriseDB PostgreSQL是“最先进的开源式数据库”,具备完全的关系能力、ACID承诺、SQL查询支持和远程复制。EnterpriseDB 是全球唯一的基于PostgreSQL的解决方案和服务供应商。他们提供的Postgres Plus Advanced Server建立在PostgreSQL内核基础之上,并且提供更多的特性和对其他数据库的兼容性。他们以非常具有竞争力的价格为你的Postgres部署提供24×7的技术支持。 Ashnik如何起作用? 我们与我们的客户合作非常紧密,能帮助他们制定一套合理的用Postgres Plus Advanced Server替代Oracle的计划。如果您有进一步的关于Oracle迁移或SQL Server迁移的咨询和服务需求,我们在Ashnik上非常乐意提供帮助。请查看我们的迁移服务。 – Sameer Kumar I Senior Solution Architect, Ashnik Sameer Kumar是与Ashnik合作的数据库解决方案架构师。他曾为一些来自零售、金融保险业、电信通讯行业的关键客户提供过许多复杂的设置和迁移任务。Sameer是经认证的PostgreSQL 和EDB Postgres Plus Advanced Server方面的专家。他同时也是一名认证的Postgres培训师,为公众及企业团体提供过许多场培训。他精通各种关系型数据库管理系统,比如DB2、Oracle和SQL Server,并且学习过noSQL技术,即MongoDB。他与客户紧密合作,帮助他们在noSQL数据库建立分析平台,从RDBMS迁移至MongoDB。他采取的是自由工作模式,喜欢辗转于新加坡各地工作的状态。

Migrating from Proprietary RDBMS to PostgreSQL Database

Sushant

Recently, I have come across numerous situations where-in the organizations were considering to move from proprietary RDBMS system to Postgres. While they are willing to move to open source databases, they  are  sceptical whether PostgreSQL will be able to meet their specific requirements which are currently being taken care of by their existing proprietary RDBMS database. On my journey from Oracle to Postgres, I have noticed the immense enthusiasm in the Postgres community worldwide to help organization relalise the benefits of open source. I will […]

FinTech – Finance meets technology, just getting started!

Rekha Ramaswamy

What Is FinTech? FinTech – Finance meets technology – using technology to disrupt financial systems. There are many sectors of banking being disrupted by Fintech including wealth management, lending, digital identity, and lifestyle banking. It would not be unfair to say that Fintech is doing to the Financial Services Industry what Uber has done to the personal transport industry – shift the focus from owning the asset to managing the asset using technology. The emphasis of Fintech is on managing money than […]
