Optimization

The application to be developed needs to be optimized keeping the following considerations in mind

• Support for high-contrast and black-and-white displays (extra credit for "night mode" and "day mode").
• UI should be touch screen friendly.
• Database schema should be normalized.
• Message search feature should be optimized to run in O(log(n)) time at least.
• Low power consumption(Assume this is to run on a device like the Raspberry Pi)
