Mimer SQL Real-Time Edition
Category: Database features
Introduction

Mimer is proud to announce the start of a collaboration project between Mimer Information Technology and Mälardalen Real-Time Research Centre at Mälardalen University with the aim of developing a real-time edition of Mimer SQL. The new member of the Mimer SQL family is intended to be used in application-areas where real-time aspects are important, such as for, vehicle systems, process automation and telecommunication systems.

The Mimer SQL Real-Time Edition, due to its efficient and predictable behavior, opens up data management for areas in which current products on the market do not suffice.

The real-time technology used in the Mimer SQL Real-Time Edition stems from well proven results originating from a 5 year research project targeting data management for vehicle control-systems.

Mimer is seeking industry partners during the integration phase of the real-time technology into the Mimer SQL product. These industry partners will have influence on the functionality and packaging of the Mimer SQL, Real-Time Edition product.



Some qualities of Mimer SQL Real-Time Edition include:
  • Modeling of both real-time and non real-time data in one database.
    The Mimer SQL Real-Time Edition will allow all data in the system to be modeled together; this removes the need of a "data pump" that passes information from the real-time parts of the system to the management parts. This way, redundant copies of data, and the need for home made data management solutions are removed.

  • Safe sharing of real-time and non real-time data during run-time.
    The technology used in Mimer SQL Real-Time Edition allow both real-time tasks and non real-time processing to independently access real-time data without risking unpredictable transaction aborts or blocking. One can say that the technology acts as a firewall between real-time and management data access.

  • Efficient and predictable real-time data access...
    Mimer SQL Real-Time Edition allows any real-time data element in the database to be accessed using a few sequential processor instructions, guaranteeing efficient and predictable access.

  • ...while still providing Mimer SQL’s No.1 in the world conformity to SQL standards.
    This is the guarantee for an open database solution where critical real-time systems can be easily accessed for diagnose and management.

  • Mimer SQL is the world leader in zero maintenance and ease-of-use.
    All the functionality in this area is built in from scratch. Non-locking transaction control, automatic on-line reorganization, automated on-line backup, self tuning kernel and tight OS integration are some of these features.

  • Mimer SQL is a robust system that has been on the market for more than 25 years.
    Opinions about Mimer SQL like "a black box database" and "an install and forget database" are customer's expressions for stability with endurance.

  • Mimer SQL is a cross platform product.
    With availability on all major platforms, ranging from mobile appliances to enterprise systems, Mimer SQL databases can be used for in all parts of a product line.

Description

As previously said, Mimer SQL Real-Time Edition allow both real-time and non real-time data to be modeled in the same database. Basically, you model all data in the system and then tag certain data as real-time. By tagging data as real-time, Mimer SQL Real-Time Edition is instructed to allocate mechanisms to ensure efficient and predictable access to it. Of course real-time data can be accessed using ordinary SQL queries, see figure below.

The Mimer SQL Real-Time Edition uses two distinctly different access methods:
  • Database Pointers
    Database pointers is an efficient access-method especially suited for real-time data. A database pointer resemble of a pointer to a shared variable, which can be accessed both for writing and for reading. Mimer SQL Real-Time Edition will ensure that any access using the database pointer is efficient, predictable and correct. Database pointers make ideal mechanisms for managing real-time data, such as sensor- and actuator-data for control-systems.

  • SQL
    SQL provides a powerful and standardized access to data. It provides mechanisms to search for, structure and update large amounts of data in an efficient manner. Mimer SQL Real-Time Edition uses a Non-locking transaction control, just as the other members of the Mimer family. Of course Mimer SQL provides full and optimized support for established and standardized interfaces, including ODBC, ADO.NET and a wide range of JDBC drivers, which makes development easy with all the popular tools such as Jboss, Tomcat, DbVisualizer, Omnis and many more.
