LESS DB
Simple database system. This module simulates database using user-provided memory source. DBMS takes care of accessing, writing and organizing data, so no knowledge of memory addressing is required for the user.
Data organization
DBMS is using blocks and sections with various parameters to organize data in memory. Image below displays possible internal data organization in memory using DBMS.
Blocks
A block of data is specified using the following parameters:
- Section
Sections
Block section is specified using the following parameters:
- Total number of parameters inside section
- Data parameter type (Bit, byte, half-byte, word or dword)
- Preserve on partial reset (if set to true, data in section won't be cleared when performing reset of data)
- Default value (value which will be assigned to all parameters inside section)
- Auto increment (if set to true, default value will be used as starting value for first parameter, and all consecutive parameters will be incremented by 1)
