技术领域technical field
本发明涉及互联网通信技术领域，尤其涉及一种基于云平台的数据库更新方法、装置、设备及介质。The present invention relates to the technical field of Internet communication, in particular to a method, device, equipment and medium for updating a database based on a cloud platform.
背景技术Background technique
结构化查询语言(StructuredQueryLanguage)，简称SQL，是一种特殊目的的编程语言，是一种数据库查询和程序设计语言，用于存取数据以及查询、更新和管理关系数据库系统。常使用版本来管理数据库内容的差异，版本可以使用SQL语句来实现。比如，可以通过基于增量的SQL语句来管理数据库版本之间的差异，以及借助命令(手动选择对应的版本)进行更新和回退操作。Structured Query Language (Structured Query Language), referred to as SQL, is a special-purpose programming language, a database query and programming language, used to access data and query, update and manage relational database systems. Versions are often used to manage differences in database content, and versions can be implemented using SQL statements. For example, the difference between database versions can be managed through incremental SQL statements, and the update and rollback operations can be performed with the help of commands (manually selecting the corresponding version).
在需要频繁跟数据库进行交互、需要频繁读取/存储数据的场景下，使用现有技术时需要工作量大且繁琐的人工工作作为支撑，以保证数据库的有效更新。然而，版本生成频繁，人工撰写SQL语句难度大；SQL语句作为一种较原始的语言，对于数据库而言，存在着关键数据信息的泄露风险；同时不能自动更新数据库，增加管理成本。因此，需要提供更高效、安全的方案。In scenarios where frequent interaction with the database is required and frequent reading/storage of data is required, the use of existing technologies requires heavy workload and tedious manual work as support to ensure effective update of the database. However, versions are generated frequently, and it is difficult to manually write SQL statements; as a relatively primitive language, SQL statements have a risk of leakage of key data information for databases; at the same time, the database cannot be automatically updated, which increases management costs. Therefore, a more efficient and secure solution needs to be provided.

Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

请参阅图1，图1是本发明实施例提供的一种应用环境的示意图，如图1所示，该应用环境中包括一云平台的相关架构，自动平台、监控平台以及运维平台可以作为架构中的业务层。云网关、IP系统以及访问鉴权系统可以作为架构中的云网关层。云平台则作为架构中的云层。云网关提供统一的云平台资源接口，云网关进行针对云平台的数据交互产生的交互数据存储于数据库中。比如云网关可以跟IP系统、访问鉴权系统和云平台本身进行数据交互。需要说明的是，图1仅仅是一种示例。Please refer to Fig. 1. Fig. 1 is a schematic diagram of an application environment provided by an embodiment of the present invention. As shown in Fig. 1, the application environment includes a related architecture of a cloud platform, and an automatic platform, a monitoring platform and an operation and maintenance platform can be used as The business layer in the architecture. The cloud gateway, IP system and access authentication system can be used as the cloud gateway layer in the architecture. The cloud platform acts as the cloud layer in the architecture. The cloud gateway provides a unified cloud platform resource interface, and the interaction data generated by the cloud gateway for data interaction with the cloud platform is stored in the database. For example, the cloud gateway can exchange data with the IP system, the access authentication system, and the cloud platform itself. It should be noted that Fig. 1 is only an example.
具体的，架构中的业务层可以提供供用户直接操作的相关平台。比如自助平台可以提供给用户一个申请云平台资源的界面；监控平台可以提供给用户监控云平台的全部资源使用情况的界面；运维平台可以提供用于管理员操作的界面，管理员可以进行宿主机迁移等操作。Specifically, the business layer in the architecture can provide related platforms for users to directly operate. For example, the self-service platform can provide users with an interface to apply for cloud platform resources; the monitoring platform can provide users with an interface to monitor the usage of all resources on the cloud platform; the operation and maintenance platform can provide an interface for administrators to operate. Operations such as host migration.
具体的，架构中的云网关层具有对外提供云平台的服务的能力。IP系统可以管理IP等网络资源；访问鉴权系统可以基于角色的权限访问控制(RBAC，Role-BasedAccessControl)进行访问用户的鉴权、认证等。用户基于访问鉴权系统的访问权限确定，可以进行对应权限内的操作，比如对该权限指向的云平台资源进行申请，对该权限指向的资源使用情况进行查看等。相应的，该用户可以对应有该权限指向的云网关数据库。Specifically, the cloud gateway layer in the architecture has the ability to provide cloud platform services externally. The IP system can manage IP and other network resources; the access authentication system can perform role-based access control (RBAC, Role-BasedAccessControl) to authenticate and authenticate access users. The user is determined based on the access authority of the access authentication system, and can perform operations within the corresponding authority, such as applying for the cloud platform resource pointed to by the authority, checking the usage of the resource pointed to by the authority, etc. Correspondingly, the user can correspond to the cloud gateway database pointed to by the permission.
具体的，架构中的云层里，云平台可以是Openstack(一个开源的云计算管理平台项目)，云平台提供着IaaS服务(InfrastructureasaService，基础设施即服务)。当然，云平台也可以是基于OpenStack开发的平台，该云平台可以实现私有云或者混合云的服务。Specifically, in the cloud layer in the architecture, the cloud platform can be Openstack (an open source cloud computing management platform project), and the cloud platform provides IaaS services (Infrastructure as a Service, infrastructure as a service). Of course, the cloud platform may also be a platform developed based on OpenStack, and the cloud platform may implement private cloud or hybrid cloud services.
以下介绍本发明一种基于云平台的数据库更新方法的具体实施例，图2是本发明实施例提供的一种基于云平台的数据库更新方法的流程示意图，本说明书提供了如实施例或流程图所述的方法操作步骤，但基于常规或者无创造性的劳动可以包括更多或者更少的操作步骤。实施例中列举的步骤顺序仅仅为众多步骤执行顺序中的一种方式，不代表唯一的执行顺序。在实际中的系统或服务器产品执行时，可以按照实施例或者附图所示的方法顺序执行或者并行执行(例如并行处理器或者多线程处理的环境)。具体的如图2所示，所述方法可以包括：The following introduces a specific embodiment of a cloud platform-based database update method of the present invention. FIG. 2 is a schematic flow diagram of a cloud platform-based database update method provided by an embodiment of the present invention. This specification provides examples or flow charts The operation steps of the method described above may include more or less operation steps based on routine or non-creative labor. The sequence of steps enumerated in the embodiments is only one of the execution sequences of many steps, and does not represent the only execution sequence. When an actual system or server product is executed, the methods shown in the embodiments or drawings may be executed sequentially or in parallel (for example, in a parallel processor or multi-thread processing environment). Specifically as shown in Figure 2, the method may include:
S201：响应于云网关进行针对云平台的数据交互产生的交互数据，生成数据库操作对象；S201: Generate a database operation object in response to the interaction data generated by the cloud gateway for data interaction with the cloud platform;
在本发明实施例中，云网关(比如Venus)进行针对云平台的数据交互，由这些数据交互产生的交互数据表征着一些业务信息(比如，异步任务信息、云平台未能提供的组合资源信息等)。这些业务信息需要以相应的数据类型、结构存储于云网关数据库中。响应于所述交互数据生成数据库操作对象(数据库操作对象可以基于进行数据交互的对应代码定义)，基于面向对象的编程思想，便于后续步骤实现以对象的操作形式更新云网关数据库。In the embodiment of the present invention, the cloud gateway (such as Venus) performs data interaction for the cloud platform, and the interaction data generated by these data interactions represents some business information (for example, asynchronous task information, combined resource information that the cloud platform cannot provide) Wait). These business information need to be stored in the cloud gateway database with corresponding data types and structures. In response to the interaction data, a database operation object is generated (the database operation object can be defined based on the corresponding code for data interaction), based on the object-oriented programming idea, it is convenient for subsequent steps to update the cloud gateway database in the form of object operation.
在一个具体的实施例中，云网关层可以是一个云平台架构中的自适应层，可以接入各种云平台。这些云平台提供的服务不限于IaaS服务，还可以包括PaaS服务(PlatformasaService，平台即服务)和SaaS服务(SoftwareasaService，软件即服务)。这些云平台可以实现对应的公有云、私有云或者混合云的服务。作为云网关层，针对不同的后端云平台有以不同的数据类型、结构在云网关数据库中进行数据存储的需求。In a specific embodiment, the cloud gateway layer can be an adaptive layer in a cloud platform architecture, which can access various cloud platforms. The services provided by these cloud platforms are not limited to IaaS services, and may also include PaaS services (Platform as a Service, platform as a service) and SaaS services (Software as a Service, software as a service). These cloud platforms can implement corresponding public cloud, private cloud or hybrid cloud services. As the cloud gateway layer, there are requirements for data storage in the cloud gateway database with different data types and structures for different back-end cloud platforms.
如图6所示，每一个云网关对应一个云平台，自助平台接入所有的云网关以提供资源纳管。每个云网关对应的云平台及其提供的服务，可以以一个机房的形式在自助平台表征。各个机房可以存在差异，那么每个云网关对应的云平台不同，云网关需要配置不同的数据结构以接入对应云平台。当然，自助平台可以提供统一的接口(可参见图6)来与不同的云网关进行数据交互。云网关层可以配置多后端数据库驱动，根据后端接入的云平台不用以实现不同的驱动。这样所述云网关数据库包括至少一个云网关子数据库，每个云网关进行针对目标云平台的数据交互产生的交互数据存储于对应的云网关子数据库中，不同的云网关子数据库中可以以不同的数据类型、结构存储对应交互数据。As shown in Figure 6, each cloud gateway corresponds to a cloud platform, and the self-service platform accesses all cloud gateways to provide resource management. The cloud platform corresponding to each cloud gateway and the services it provides can be represented on the self-service platform in the form of a computer room. There may be differences in each computer room, so each cloud gateway corresponds to a different cloud platform, and the cloud gateway needs to be configured with a different data structure to access the corresponding cloud platform. Of course, the self-service platform can provide a unified interface (see Figure 6) for data interaction with different cloud gateways. The cloud gateway layer can be configured with multiple back-end database drivers, which can be used to implement different drivers according to the cloud platform connected to the back-end. In this way, the cloud gateway database includes at least one cloud gateway sub-database, and each cloud gateway performs data interaction for the target cloud platform. The interactive data generated by the data interaction is stored in the corresponding cloud gateway sub-database. The data type and structure store corresponding interactive data.
进一步的，对于如图7所示涉及多个云平台的应用环境，可以在云网关与对应的云网关子数据库之间设置对应的标识。比如，根据每个所述云网关对应的所述交互数据和标识信息，生成目标数据库操作对象，所述标识信息指向与所述云网关对应的所述云网关子数据库。在进行针对多个云平台的多云管理时，能够降低后续进行数据库更新的难度。Further, for an application environment involving multiple cloud platforms as shown in FIG. 7 , a corresponding identifier may be set between the cloud gateway and the corresponding cloud gateway sub-database. For example, a target database operation object is generated according to the interaction data and identification information corresponding to each cloud gateway, and the identification information points to the cloud gateway sub-database corresponding to the cloud gateway. When performing multi-cloud management for multiple cloud platforms, it can reduce the difficulty of subsequent database updates.
S202：基于创建的数据库结构与对象模型的映射关系，比较云网关数据库对应的数据库对象与所述数据库操作对象，确定待处理数据库对象和所述待处理数据库对象对应的处理信息；S202: Based on the created mapping relationship between the database structure and the object model, compare the database object corresponding to the cloud gateway database with the database operation object, and determine the database object to be processed and the processing information corresponding to the database object to be processed;
在本发明实施例中，云网关数据库可以是直接使用SQL语句操作的，云网关数据库可以为Mysql(一个关系型数据库管理系统)。如图4所示，云网关数据库的数据库结构对应图中右侧的结构：数据库、数据表、字段，数据库包括数据表，数据表包括字段(表项)。In the embodiment of the present invention, the cloud gateway database can be operated directly using SQL statements, and the cloud gateway database can be Mysql (a relational database management system). As shown in Figure 4, the database structure of the cloud gateway database corresponds to the structure on the right side of the figure: database, data table, field, the database includes data tables, and the data table includes fields (table items).
在一个具体的实施例中，可以将数据库和数据表分别映射成对象，表对象包含在库对象的属性中，数据表中的字段是表对象的属性。比如，如图4所示，所述映射关系通过执行下述步骤创建，包括：建立库对象(ObjectA)与所述云网关数据库(数据库A)之间的第一映射关系；建立表对象(Objecta)与所述云网关数据库中的数据表(表a)之间的第二映射关系；所述库对象(ObjectA)的属性信息包括所述表对象(Objecta，Objectb，Objectc)，所述表对象(比如Objectc)的属性信息记录有所述数据表中的字段值(比如表c的字段1、字段2和字段3)。使用对象模型跟数据库中的库、表等结构进行一对一映射，方便以对象的操作形式更新数据库中的业务信息，可以避免了书写基于增量的SQL语句的繁琐人工操作，降低了维护数据库的难度及成本。In a specific embodiment, the database and the data table can be mapped into objects respectively, the table object is included in the properties of the library object, and the fields in the data table are the properties of the table object. For example, as shown in Figure 4, the mapping relationship is created by performing the following steps, including: establishing the first mapping relationship between the library object (ObjectA) and the cloud gateway database (database A); establishing a table object (ObjectA ) and the second mapping relationship between the data table (table a) in the cloud gateway database; the attribute information of the library object (ObjectA) includes the table object (Objecta, Objectb, Objectc), and the table object (such as Objectc) attribute information records field values in the data table (such as field 1, field 2 and field 3 of table c). Using the object model to perform one-to-one mapping with the library, table and other structures in the database, it is convenient to update the business information in the database in the form of object operation, which can avoid the tedious manual operation of writing incremental SQL statements and reduce the maintenance of the database difficulty and cost.
在另一个具体的实施例中，所述基于创建的数据库结构与对象模型的映射关系，比较云网关数据库对应的数据库对象与所述数据库操作对象，确定待处理数据库对象和所述待处理数据库对象对应的处理信息，包括：首先，根据所述映射关系和所述云网关数据库，生成所述云网关数据库对应的云网关数据库对象模型，可以参考图4。然后，根据所述云网关数据库对象模型中的数据库对象与所述数据库操作对象的差异，确定所述待处理数据库对象和所述处理信息。通过类似面向对象编程的思想，实现数据库结构的对象化，将数据库中的内容以对象的方式进行管理，这样可以在对象层次(比如代码操作对象)查看数据库以及确定数据库是否有增删改的需求。In another specific embodiment, based on the mapping relationship between the created database structure and the object model, the database object corresponding to the cloud gateway database is compared with the database operation object, and the database object to be processed and the database object to be processed are determined. The corresponding processing information includes: first, according to the mapping relationship and the cloud gateway database, generating a cloud gateway database object model corresponding to the cloud gateway database, as shown in FIG. 4 . Then, according to the difference between the database object in the cloud gateway database object model and the database operation object, the database object to be processed and the processing information are determined. Through an idea similar to object-oriented programming, the objectification of the database structure is realized, and the content in the database is managed in the form of objects, so that the database can be viewed at the object level (such as code operation objects) and whether there is a need to add, delete, or modify the database.
在另一个具体的实施例中，如图3所示，所述基于创建的数据库结构与对象模型的映射关系，比较云网关数据库对应的数据库对象与所述数据库操作对象，确定待处理数据库对象和所述待处理数据库对象对应的处理信息，包括：In another specific embodiment, as shown in FIG. 3, the database object corresponding to the cloud gateway database is compared with the database operation object based on the mapping relationship between the created database structure and the object model, and the database object to be processed and the database operation object are determined. The processing information corresponding to the database object to be processed includes:
S301：创建比较对象队列，所述比较对象队列中包括按照数据库操作顺序输入的至少一个所述数据库操作对象；S301: Create a comparison object queue, where the comparison object queue includes at least one database operation object input according to the database operation sequence;
可以列举出在预设时间段内的数据库操作对象，将它们按照数据库操作顺序输入比较对象队列中。The database operation objects within the preset time period can be listed, and they are input into the comparison object queue according to the database operation sequence.
可以在云网关每次重启的时候，自动使用前述映射关系将目前代码中定义的数据库操作对象与云网关数据库对应的数据库对象进行比较，检查差异，以便自动更新。当然，可以选择不触发自动更新，进行对应的业务流程运行。Every time the cloud gateway restarts, it can automatically use the aforementioned mapping relationship to compare the database operation object defined in the current code with the corresponding database object of the cloud gateway database, and check the difference for automatic update. Of course, you can choose not to trigger the automatic update to run the corresponding business process.
S302：以多线程并发的执行方式，按照所述数据库操作顺序从所述比较对象队列中抽取出每个所述数据库操作对象；S302: Extract each of the database operation objects from the comparison object queue according to the database operation sequence in a multi-thread concurrent execution manner;
可以根据数据库操作顺序多个抽取线程，每个抽取线程用于从比较对象队列中抽取一个数据库操作对象，多个抽取线程并发执行。Multiple extraction threads can be used according to the database operation sequence, each extraction thread is used to extract a database operation object from the comparison object queue, and multiple extraction threads are executed concurrently.
S303：根据每个所述数据库操作对象与所述云网关数据库对应的数据库对象之间的差异，确定每个所述数据库操作对象对应的所述待处理数据库对象和所述处理信息；S303: Determine the database object to be processed and the processing information corresponding to each database operation object according to the difference between each database operation object and the database object corresponding to the cloud gateway database;
可以比较数据库操作对象的属性与数据库对象的属性(比如库对象的属性信息、表对象的属性信息)，进而确定待处理数据库对象和处理信息。待处理数据库对象可以指向当前数据库已存在的数据库对象，处理信息可以是修改该数据库对象的属性或删除该数据库对象。待处理数据库对象可以指向当前数据库不存在的数据库对象，处理信息可以是增加该数据库对象。The attribute of the database operation object and the attribute of the database object (such as the attribute information of the library object and the attribute information of the table object) can be compared, and then the database object to be processed and the processing information can be determined. The database object to be processed may point to an existing database object in the current database, and the processing information may be to modify the attribute of the database object or delete the database object. The database object to be processed may point to a database object that does not exist in the current database, and the processing information may be to add the database object.
进一步的，数据库操作对象对应有表征当前状态的属性数据以及表征改变当前状态的操作信息。可以生成基于数据库操作对象(比如代码操作对象)对应的SQL语句，在云网关数据库中进行查询，查询是否存在数据库操作对象指向的属性数据，若不存在则创建对应的数据库、数据表等。也可以列出云网关数据库当前存在的数据库、数据表等，查询数据库操作对象指向的属性数据中是否存在对应的数据库对象，若不存在则不将该数据库对象确定为待处理数据库对象。Further, the database operation object corresponds to attribute data representing the current state and operation information representing changing the current state. It can generate SQL statements corresponding to database operation objects (such as code operation objects), query in the cloud gateway database, and check whether there is attribute data pointed to by the database operation object, and create corresponding databases, data tables, etc. if it does not exist. It is also possible to list the databases, data tables, etc. that currently exist in the cloud gateway database, and query whether there is a corresponding database object in the attribute data pointed to by the database operation object. If it does not exist, the database object will not be determined as the database object to be processed.
S304：根据每个所述数据库操作对象对应的所述待处理数据库对象和所述处理信息，生成每个所述数据库操作对象对应的差异处理操作对象；S304: Generate a differential processing operation object corresponding to each database operation object according to the database object to be processed corresponding to each database operation object and the processing information;
待处理数据库对象指向当前数据库不存在的数据库对象，处理信息为增加该数据库对象时，差异处理操作对象可以对应ObjectA实例化，创建一个Object A的实例，对应在云网关数据库中创建数据库和数据表；差异处理操作对象可以对应Objecta实例化，对应在云网关数据库中向表a插入数据。The database object to be processed points to a database object that does not exist in the current database. When the processing information is to add the database object, the difference processing operation object can be instantiated corresponding to ObjectA, and an instance of Object A is created, corresponding to the database and data table created in the cloud gateway database. ; The difference processing operation object can be instantiated corresponding to Objecta, corresponding to inserting data into table a in the cloud gateway database.
待处理数据库对象指向当前数据库已存在的数据库对象，处理信息为修改该数据库对象的属性时，差异处理操作对象可以对应修改ObjectA的属性或者修改Objecta的属性。The database object to be processed points to an existing database object in the current database, and when the processing information is to modify the attribute of the database object, the difference processing operation object can modify the attribute of ObjectA or modify the attribute of Objecta correspondingly.
待处理数据库对象指向当前数据库已存在的数据库对象，处理信息为删除该数据库对象时，差异处理操作对象可以对应销毁数据库对象的实例。比如数据库对象为库对象时，销毁该库对象，表对象以及表对象的属性也对应销毁。The database object to be processed points to an existing database object in the current database, and when the processing information is to delete the database object, the difference processing operation object may correspond to the instance of the database object being destroyed. For example, when the database object is a library object, when the library object is destroyed, the table object and the attributes of the table object are also destroyed accordingly.
S305：创建差异对象队列，所述差异对象队列中包括按照所述数据库操作顺序输入的各个所述差异处理操作对象。S305: Create a difference object queue, where the difference object queue includes each of the difference processing operation objects input according to the database operation sequence.
将这些差异处理操作对象按照数据库操作顺序输入比较对象队列中。如图5所示，这些差异处理操作对象对应一个个operation操作实例。可以根据每一种操作实现数据库差异的补齐。可以通过在云网关启动时检查数据库操作对象和数据库中的信息的差异，生成相应的差异处理操作对象，进而通过差异操作完成数据库自动更新。These difference processing operation objects are input into the comparison object queue according to the database operation sequence. As shown in Figure 5, these difference processing operation objects correspond to each operation operation instance. Completion of database differences can be realized according to each operation. By checking the difference between the database operation object and the information in the database when the cloud gateway is started, a corresponding difference processing operation object can be generated, and then the automatic update of the database can be completed through the difference operation.
在另一个具体的实施例中，对于如图6所示涉及多个云平台的应用环境，所述云网关数据库包括至少一个云网关子数据库，每个所述云网关进行针对目标云平台的数据交互产生的交互数据存储于对应的所述云网关子数据库中。所述基于创建的数据库结构与对象模型的映射关系，比较云网关数据库对应的数据库对象与所述数据库操作对象，确定待处理数据库对象和所述待处理数据库对象对应的处理信息，包括：首先，根据每个所述目标数据库操作对象对应的所述标识信息，从所述云网关数据库中确定用于比较的目标云网关子数据库；然后，比较所述目标云网关数据库对应的数据库对象与所述目标数据库操作对象，确定所述待处理数据库对象和所述处理信息。这样便于通过对象模型实现多云的自动化数据管理，以及实现对多云平台的自动扩容。解决了多云平台因多后端数据库驱动数据差异大更加难以管理的问题。当多云平台需要扩容时，可以部署一个新的云网关，并配置相应的后端云平台驱动，进而通过对象模型实现相关数据的同步初始化。In another specific embodiment, for an application environment involving multiple cloud platforms as shown in Figure 6, the cloud gateway database includes at least one cloud gateway sub-database, and each of the cloud gateways carries out data The interaction data generated by the interaction is stored in the corresponding cloud gateway sub-database.
