January 19, 2017. Beijing PeerSafe Technology Co., Ltd. releases Blockchain Log Database Chainsql White Paper, AlAisc (Multiple Active Database Middleware) White Paper and AlBisc (Database Disaster Recovery) White Paper.
The white paper said, as the first blockchain database application platform in the world，chainsql combines the properties of the blockchain and traditional distributed database, all operations on the data table in the form of log records in the block chain. The user can customize the configuration of the table you want to synchronize to a local database. At the same time, this database can be tamper-resistant and recovered at any time.
ChainSQL supports multiple languages API, is compatible with a variety of databases, and can realize plug-in management of data. Commonly used databases include DB2, Firebird, MySQL, ODBC, PostgreSQL, SQLite3, etc., can be used as plug-ins by configuration, the traditional database access cost is very low.
As a general practice, enterprises will usually build their data center in the mode of “two lands & three centers” to avoid the risks of centralized database and reduce or eliminate the influences shutdown has on service availability. This mode promotes the service continuity of the enterprise to some extent, but it also increases the input of IT resources and funds as the standard for the disaster recovery system increases. AlAisc makes all the data center have production functions, greatly reduces the cost of the enterprise from the development side. AlAisc can easily add nodes online at any time, not affect the original multi-active system, and save the cost of business expansion. This middleware can upgrade and maintain the software and hardware of each node online by means of roll polling to reduce the cost.
AlBisc supports the one-to-one and one-to-many deployment modes of the production center and the disaster recovery center. That is, more than one disaster recovery centers can back up the data at the same time. As the underlying technology of the blockchain is adopted, it is possible to ensure that the data of each disaster recovery center can be confirmed and written in the middleware at the same time to ensure the strong consistency of the data of multiple copies. The impact of the number of copies on RPO is very small and can be considered as insignificant. In case of multiple disaster recovery centers, AlBisc can upgrade the software and hardware of each disaster recovery center by means of roll polling without any impact on the services of the production center and other disaster recovery centers.
