Description

区块链中数据字段的更新方法、装置、介质、电子设备
本申请要求于2019年07月24日提交中国专利局、申请号为201910671356.0、申请名称为“区块链中数据字段的更新方法、装置、介质、电子设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电数字数据处理技术领域,特别涉及一种区块链中数据字段的更新方法、装置、介质及电子设备。
背景技术
近年来,随着计算机和互联网技术的发展,“数据”已经和我们的工作与生活息息相关,而大数据时代的来临也使得我们与数据之间的联系越来越紧密,如今,我们生活中大多数的工作都需要围绕着数据而展开。大量的数据需要得到科学的管理,在管理数据的过程中,我们经常会因为工作的上的要求需要对数据进行更新,因此,如何优化数据更新工作的便捷性从而提高数据管理效率就显得十分重要。
在现有技术中,区块链系统中的存储方式均是key-value(key是关键字,value是值)格式,而且大部分value数据均是加密保存的。当对一条数据中的某些字段做更新操作时,上层应用一般需要经历调用数据查询接口,然后更新数据,最后调用数据上链接口的流程。
然而,现有技术中的数据更新需要上层应用将整个value的全量数据传入区块链系统中。一方面,现有技术只能将整个value的全量数据传入区块链系统中而不能重点关注只需要更新的字段,这样会带来计算机资源浪费技术问题。另一方面,这样的数据更新方法也会增加区块链和上层应用之间的数据交互,复杂了数据交互流程,对于开发者和使用者而言,该方法的易用性和友好程度非常低,会造成数据管理效率降低的技术问题。
发明内容
在电数字数据处理技术领域,为了解决相关技术中存在因对区块链中一条 数据做更新操作时需要传入整个value的全量数据而带来的计算机资源浪费和降低数据管理效率的技术问题。本申请提供了一种区块链中数据字段的更新方法、装置、介质及电子设备。
根据本申请的一方面,提供了一种区块链中数据字段的更新方法,所述方法包括:
响应于用户关于数据更新的请求,获取需要更新的数据对象,所述数据对象中包括第一Key值和与第一Key值对应的更新字段数据;
根据所述数据对象中的第一Key值,在区块链系统中确定与第一Key值相关联的全量数据;
结合所述更新字段数据,读取所述全量数据,以在全量数据中确定需要被更新的字段;
将所述在全量数据中确定的需要被更新的字段更新为所述更新字段数据。
根据本申请的另一方面,提供了一种区块链中数据字段的更新装置,所述装置包括:
获取模块,用于获取需要更新的数据对象;
确定模块,用于在区块链系统中确定与第一Key值相关联的全量数据;
读取模块,用于结合所述更新字段数据,读取所述全量数据,以在全量数据中确定需要被更新的字段;
更新模块,用于将所述在全量数据中确定的需要被更新的字段更新为所述更新字段数据。
根据本申请的另一方面,提供了一种计算机可读程序介质(计算机可读存储介质),其存储有计算机程序指令,当所述计算机程序指令被计算机执行时,使计算机执行如前所述的方法。可选的,该计算机可读存储介质可以为非易失性可读存储介质。
根据本申请的另一方面,提供了一种电子设备,所述电子设备包括:
处理器;
存储器,所述存储器上存储有计算机可读指令,所述计算机可读指令被所述处理器执行时,实现如前所述的方法。
由以上本申请的技术方案,与现有技术相比,本申请的技术方案通过利用 区块链系统中的数据是以Key-value格式进行存储的特点,来实现以第一Key值为线索在区块链系统中确定需要被更新的全量数据(value值),并对全量数据中需要被更新的一个或者几个字段进行更新。其显著的有益效果在于:本方案能够解决现有技术中存在的因对一条数据做更新操作时需要传入整个value的全量数据而带来的计算机资源浪费和降低数据管理效率的技术问题。
附图说明
此处的附图被并入说明书中并构成本说明书的一部分,示出了符合本申请的实施例,并与说明书一起用于解释本申请的原理。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。
此外,附图仅为本公开的示意性图解,并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分,因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体,不一定必须与物理或逻辑上独立的实体相对应。
本公开首先提供了一种区块链中数据字段的更新方法。所述数据字段是指记录在区块链系统中的可以用来表征某一事件对象属性、特征的文字、符号以 及数字等抽象化的信息单元载体。本申请的实施环境可以是便携移动设备,例如智能手机、平板电脑、笔记本电脑等,也可以是各种固定式设备,例如,计算机设备、现场终端、台式电脑、服务器、工作站等。
图1是根据一示例性实施例示出的区块链中数据字段更新方法的应用场景示意图。在区块链中,不同节点之间可以实现资源与信息的共享,也正是因为如此,区块链技术在我们的生活与工作中得到了快速的普及。例如企业、政府以及事业单位就将一些信息与数据存储在区块链中以实现共享。具体的,比如可以在10所大学之间建立区块链,进行学生的课程信息共享。还比如可以在企业内部的不同子系统之间建立用于耗材管理的区块链,进行耗材相关信息的共享。如上所述,存储在区块链中的大量数据需要得到科学的管理,而在管理数据的过程中,经常需要对某一些数据进行更新,因此,如何优化数据更新工作的便捷性从而提高数据管理效率就显得十分重要。在图1所示的实施例的应用场景中,本申请设计了一个专门针对于区块链系统的字段更新接口102,该接口内部实现了先从区块链101上读取全量数据,然后将需要修改的数据整合到全量数据中,最后一次性将数据提交至区块链。通过该方案,上层应用在更新数据时不需要先调用数据查询接口,再更新数据,再调用数据上链接口这么麻烦的流程。如此可以减少区块链和上层应用的数据交互,简化了交互流程,让上层应用重点关注要更新的字段即可。下面将通过具体实施例对本申请的发明内容进行详细说明。
图2是根据一示例性实施例示出的一种区块链中数据字段的更新方法的流程图。如图2所示,此方法包括以下步骤:
步骤210,响应于用户关于数据更新的请求,获取需要更新的数据对象,所述数据对象中包括第一Key值和与第一Key值对应的更新字段数据。
具体的,在一个实施例中,区块链中的节点分别是A公司和B公司,区块链的中存储的数据是A公司与B公司之间的订单数据,其中A公司为卖方,B公司为买方。那么,以A公司和B公司为节点的区块链系统中需要被更新的数据对象的全量数据可以是:“订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:华为”、“订单价格:3000元/台”、“订单数量:200台”。而所述需要更新的数据对象 中的第一Key值就可以是指一个编号(例如“订单编号:0001”),所述第一Key值对应的更新字段数据可以是指“订单对象品牌:苹果牌”、“订单价格:4000元/台”、“订单数量:100台”。
在本申请中,所述需要更新的数据对象的获取方式可以有多种。例如,可以使用采集设备或者采集单元从存有相关数据对象的数据库中采集得到。也可以是通过数据的传输介质,读取或者接收用户发送的数据。还可以通过物理硬盘拷贝得到,再或者是通过工作人员手动输入而得到。
步骤220,根据所述数据对象中的第一Key值,在区块链系统中确定与第一Key值相关联的全量数据。
这里需要注意的是,在区块链系统中,所有全量数据均关联有一个唯一的第二Key值,所述第二Key值的一个重要功能就在于标识其对应的全量数据,例如在如前所述实施例中的“订单编号:0001”。
在一个实施例中,根据所述数据对象中的第一Key值,在区块链系统中确定与第一Key值相关联的全量数据可以通过如下方式完成:
如图3是根据图2对应实施例示出的一实施例的步骤220的细节流程图,具体包括以下步骤:
步骤2201,根据所述数据对象中的第一Key值,在区块链系统中查找与所述第一Key值相同的第二Key值。
步骤2202,将所述查找的第二Key值对应的全量数据确定为与第一Key值相关联的全量数据。
区块链系统中都存有若干条全量数据,每一条全量数据对应有一个第二Key值,第二Key值的作用在于标识其对应的全量数据。在一个实施例的具体实现中,例如,以A公司和B公司为节点的区块链系统中存在一条全量数据:“订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:华为”、“订单价格:3000元/台”、“订单数量:200台”。那么,可以将“订单编号:0001”作为标识此全量数据的第二Key值。如果所述数据对象中的第一Key值也为“订单编号:0001”,即将全量数据““订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:华为”、“订单价格:3000 元/台”、“订单数量:200台””作为与第一Key值“订单编号:0001”相关联的全量数据。
步骤230,结合所述更新字段数据,读取所述全量数据,以在全量数据中确定需要被更新的字段。
在一个实施例中,结合所述更新字段数据,读取所述全量数据,以在全量数据中确定需要被更新的字段可以通过如下方式完成:
如图4是根据图2对应实施例示出的一实施例的步骤230的细节流程图,具体包括以下步骤:
步骤2301,在所述全量数据中确定与所述更新字段数据中的字段名称相同的字段名称。
步骤2302,将所述在全量数据中被确定的字段名称对应的字段作为需要被更新的字段。
在一个实施例的具体实现中,所述获取的需要更新的数据对象中除了包含有第一Key值之外,还包含有一个或者几个需要更新的字段数据。例如,在以A公司和B公司为节点的区块链系统中需要被更新的数据对象的全量数据为:“订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:华为”、“订单价格:3000元/台”、“订单数量:200台”。而所述获取的需要更新的数据对象中的更新字段数据为“订单对象品牌:苹果牌”、“订单价格:4000元/台”、“订单数量:100台”。基于此,可以确定的是,在原始的全量数据““订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:华为”、“订单价格:3000元/台”、“订单数量:200台””中,““订单对象品牌:华为”、“订单价格:3000元/台”、“订单数量:200台””即为需要被更新的字段。
步骤240,将所述在全量数据中确定的需要被更新的字段更新为所述更新字段数据。
在一个实施例中,所述将在全量数据中确定的需要被更新的字段更新为所述更新字段数据,具体包括:参照所述字段名称,将所述在全量数据中确定的需要被更新字段的字段值对应的替换为所述更新字段数据中的字段值。
具体的,例如,在以A公司和B公司为节点的区块链系统中需要被更新的数据对象的全量数据为:“订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:华为”、“订单价格:3000元/台”、“订单数量:200台”。而所述获取的需要更新的数据对象中的更新字段数据为“订单对象品牌:苹果牌”、“订单价格:4000元/台”、“订单数量:100台”。那么在将所述在全量数据中确定的需要被更新的字段更新为所述更新字段数据之后,更新后的全量数据即为:“订单编号:0001”、“订单卖方:A公司”、“订单买方:B公司”、“订单对象:手机”、“订单对象品牌:苹果牌”、“订单价格:4000元/台”、“订单数量:100台”。
此外,在将所述全量数据中确定的需要被更新的字段更新为所述更新字段数据之后,所述方法还可以包括:将被更新完成的全量数据与对应的第二Key值相关联的上传至区块链系统中。
在将被更新完成的全量数据与对应的第二Key值相关联的上传至区块链系统中之前,所述方法可以包括:在所述被更新完成的全量数据中添加操作记录标签。
在一个实施例中,所述操作记录标签可以是指操作时间的标签。
在一个实施例中,所述操作记录标签也可以是关于操作人员信息的标签。
在一个实施例中,所述操作记录标签还可以是指综合操作时间和关于操作人员信息的标签。
如上所述的实施例的好处在于,通过对所述被更新完成的全量数据中添加操作记录标签,方便在以后对存储在区块链系统中的全量数据进行监控和管理。
在将被更新完成的全量数据与对应的第二Key值相关联的上传至区块链系统中之前,所述方法还可以包括:对所述被更新完成的全量数据进行加密处理,以得到加密后的全量数据。
在一个实施例中,对所述被更新完成的全量数据进行加密处理是通过DES算法实现的。
在一个实施例中,对所述被更新完成的全量数据进行加密处理是通过RSA算法实现的。
在一个实施例中,对所述被更新完成的全量数据进行加密处理是通过AES算法实现的。
如上所述,可以理解的是,对所述被更新完成的全量数据进行加密处理的方式可以是任意的,并不限于如上所示出的那些。
如上所述的实施例的好处在于,通过对所述被更新完成的全量数据进行加密处理可以实现区块链系统中的数据隐蔽,从而起到保护数据的安全的作用。
综上所述,通过从区块链系统中读取全量数据,然后将需要修改的数据整合到全量数据中,最后一次性将数据提交至区块链系统,可以使得上层应用在更新数据时不需要先调用数据查询接口,再更新数据,再调用数据上链接口这么麻烦的流程,如此能够减少计算机资源的浪费和提高数据的管理效率。
