Market positioning
The GBase 8d directory database of Common Data is the domestic No.1 brand of directory database, taking up a share of over 80% in the PKI/PMI market, and occupying a leading position in terms of market, technology, service and qualifications.
 
Technical characteristics and advantages
GBase 8d adopts the tree structure for storing individual and institutional information, to facilitate distributed databases in the fast distributed query mode, which is a dedicated database for managing personnel, certificates, domain names, e-mail addresses and other network resource information. GBase 8d is the commercial enterprise directory service system fully compliant with LDAP v3 standard. It supports the construction of large-scale deployment of distributed systems, high concurrent queries, and high-capacity storage. It is also equipped with a monitoring system and a backup and recovery system that supports HA, load balancing, and other high availability deployment modes.
 
1. Copy technology
The copy function in the directory is based on the “push” or “pull” technology, which is a mechanism that distributes part or all of the data on one directory server to other directory servers. GBase 8d supports whole-tree copy and subtree copy, as well as one-master-one-slave, one-master-multi-slave, cascading copy and other copy modes. 
2. Directory references
The referral is a mechanism that supports distributed directory. It can split LDAP namespaces by using multiple servers, and can arrange LDAP servers in the form of hierarchy. Specifically speaking, different parts of the directory are stored in different directory servers, and the directories are connected via the referral.
3. Backup and Recovery
GBase 8d supports data backup and recovery mechanism, cold and hot backups, full, incremental, and differential backups.
4. Security Enhancements
The enhanced version has obtained the national encryption and commercial encryption model certificates. It supports the separation of powers of administrators, security audits, and the encryption of audit logs. It adopts hardware encryption, and use the algorithm specified by the State Encryption Administration, to encrypt the stored directory data. It supports the security management of the password being used, including password generation, storage, use, distribute, undo, backup/restore.
5. Monitoring System
GBase 8d provides a supporting monitoring system to monitor large-scale distributed and deployed directory systems and effectively manage numerous directories in the system, which is easy for maintenance; it can monitor the directory service, copy, and server resource usage in the system, and provides exception alerting and early warning mechanism, the analysis capability, and provides decision support for system upgrades.
6. Virtual Directory System
GBase 8d provides the supporting virtual directory system to support separate storage of data in the case of large data volumes, as well as unified logic mechanism; for example: 40 million entries can be stored in five directory service systems, 8 million entries each; and then, the virtual directory system turns the five directories into a logically unified virtual directory for external services; it is transparent to applications, while bringing great convenience for maintenance; at the same time, it can greatly improve performances, providing good expansion support for large data amounts.
 
Typical applications
GBase 8d is mainly used in large distributed directory system in government, national defense, financial and electric power and other industries. Currently, it has formed a dominant position in the domestic information security industry. More than 80% of the domestic security authentication systems are using GBase 8d directory database. The largest directory of application system and the busiest directory application system in China have adopted GBase 8d. GBase 8d products have accessed more than 20 government agencies including police, security, NPC, CPPCC, central government office, quality control, industrial and commercial sectors. 
GBase 8d products are mainly used in large distributed directory systems in government, defense, finance, electric power and other industries, which is an application system targeted at precise positioning, quick queries and large-scale distribution and deployment. For example:
