You can develop and diagnose the perormance of more than 20 relational databases, data warehouses, and NoSQL databases in a graphical development environment. The security collaborative control mode of DMS ensures data security with R & D specification, R & D process, permission control, data desensitization, security audit and change rollback.

Common problems solved

  • Unified management of cloud resources

    Supports unified management of cloud databases and self-built databases of ECS servers shared by multiple cloud accounts across multiple regions.

  • Secure non-cloud resource management

    You can access the on-premises IDC self-built databases, the cloud databases of business partners, and the on-premises databases on the cloud servers of business partners through the VPC leased line and the VPN gateway.

Data security solutions

Continuous database access management

Implements fine-grained permission control by querying, exporting, and changing instances, libraries, tables, sensitive fields, and data rows; avoids database service problems and massive data leakage by controlling the full table scan limit, query timeout, query number of rows, and query times of large tables; the operation log is used to comprehensively record and present the operations of each cloud account in DMS products, helping enterprises to achieve compliance audit support for each operation.

Common problems solved

  • Limits personnel access the database

    After logging on to DMS, you can apply for permissions as needed. Therefore, after the operation is initiated in the product, it must be authenticated before the product is sent to the database. The personnel no longer access the database.

  • Fine-grained permission management

    You can apply for database-, table-, field-, and row-level data object permissions on demand. You can apply for query, export, and change permissions for related operations in different contexts. Permissions will be automatically retracted after expiring. Operations without permissions can not be started initially.

  • Data security assurance

    The number of rows returned by each query, the total number of queries per day, and the total number of rows queried per day are controllable and auditable on demand to avoid the outflow of a large amount of data; Sensitive fields are marked in necessary to avoid unnecessary data contact

  • Data Query performance security

    The extra time taken for a query and the threshold of full table scan for large tables are configured on demand to prevent slow queries from affecting the provision of database services.

Keeping stable during changes

Covers the whole process of data change, structure change and code release

The release of table structure design specifications and multiple sets of environments in the process of project development, assurance that the compliance of each SQL is indexed before bringing it online, and every update of production data are closely related to the stable condition of business services. The security collaborative control mode of DMS guarantees a smooth implementation before, during and after each change, and reduces all mistakes incurred.

Common problems solved

  • Structure free of locking the table and ability to change data without locking the table.

    All DDL operations in versions before MySQL5.6 and part of operations after that can not be changed without locking the table. Once the table is locked, the business will be directly affected. Disorder of the unique clean-up logic of each project in the database, constant waste of R & D costs, and difficulty in unified management are avoided when cleaning historical data on a large-scale basis.

  • SQL audit column goes online

    Submits SQL text,. xml SQL files, and then the system automatically identify non-compliant SQL statements such as SQL injection, non-indexed SQL, queries returned without specifying fields, writing operations without specifying fields, to avoid production problems

  • Security of stability during changes

    When the database is under heavy load, if you continue making changes, the database performance may be abnormal or even fail to function. All-round detection before, during, and after the change, is the core guarantee for the smooth implementation of changing data

  • Data tracing and rollback

    DMS security collaborative management and control mode helps you easily solve the worries of millions of abnormal data recovery. It can effectively avoid erroneous deletion and update of data, and also support rapid retrospective recovery of mistakenly updated data.

Solutions for database DevOps

Unified Enterprise metadata, process management, R & D collaboration platform

Provides a brand new working model. Based on the unified management of database resources in the enterprise, all operations that need to interact with the database can be completed here. In accordance with different businesses, different R & D specifications, R & D processes, and approval processes are designed and implemented for the corresponding instances, realizing a flexible and secure database development process to build an enterprise-exclusive database DevOps process

Common problems solved

  • Table structure design specification, multi-environment table structure consistency release process

    Enables four types of databases, which are MySQL, PolarDB-MySQL, DRDS, and OceanBase to formulate flexible design specifications and release processes at the instance level. This ensures that the table structure of multiple environments is completely consistent. Problems incurred by inconsistency will be avoided

  • Field-level concurrent and collaborative management of table structure

    Project diversity as well as frequent iterations of a task make it necessary to adjust to different fields. On contrary to traditional solutions where the update of a project may interfere with the other, the security collaborative control mode of DMS employs the ticketing system on a structural basis to enable different projects to work separately without interfering with each other. They can be released iteratively smoothly based on respective demands.

  • Instance-level security rules

    Strict control in traditional database management schemes makes personnel busy with a large number of approval operations, which will easily lead to errors and omissions caused by fatigue. Loose control makes it easy to make changes, causing run-away production With the security collaborative control mode of DMS, design specifications, operation specifications, and approval processes are customized on demand based on different database instances, which not only ensures the safe use of the database, but also ensures the R & D efficiency of enterprises.

  • New work mode

    It is difficult to train a full-time DBA. However, Using DMS, managers without database-related technical background can be instantly empowered to be equivalent to a professional DBA with the default configuration of the product. R & D personnel submit operations on demand in the product. Operations are then automatically tested in accordance with safety rules to ensure the smooth implementation of the approval process and changes, greatly reducing the investment of personnel costs and improve the R & D efficiency of enterprises
