А7: Object Database
The foundation of A7 is an object database without any binding to a programming language. A7 ODB means speed and flexibility.
Optimisation for quickly changing systems.
Object-oriented data model
Trees, links, rows
Events during changes
А7: Distributed Data
А7: Temporary Database
A7 TDB is a specialized solution, which may be applied to work with scientific, meteorological, industrial and financial data.
Storage of data that constantly change in time, like stock prices and currencies, temperature and pressure values and many other.
High speed of record and reading data
Automatic creation of data layers
Automatic creation of history data storage
A7 has a powerful mechanism of external distributions that allows:
Making distributed calculations,
Interacting with real and virtual devices,
Connecting to the Internet services.
You can use either an open protocol or SDK for creating external distributions of A7.
А7: Expansion Packages
A7: GIS Packages
Water supply system
A7: Communication and Industrial Packages
Packages allow to pretty easily integrate millions of devices. There are supported clustering, load balancing and reservation.
Industrial appliances (MODBUS TCP, MODBUS RTU, MODBUS ASCII)
Connectivity to SCADA systems and OPC servers is available:
OPC DA (for working with OPC servers)
A7: Data Exchange Packages
А7: Система разграничения доступа
A7 has two systems of selectable access. The first one is maximally fast, optimized for industrial and scientific experiments, and the second one is maximally flexible.
All the rights in the system are being implemented on the group base. There can be any number of users in the system, but only 8 groups.
Any A7 object can have a custom access level set by groups.
The number of groups, subgroup nesting and users is not limited.
Any A7 object can have a custom access level set by groups or users.
There is added the set of rights for ease of administration: the roles.
The system maintains virtualization — there is created a separated space inside A7 with its own data, users, groups and an owner.
