Import StormDB from 'stormdb ';// start db with './db.stormdb' storage location const engine = new StormDB. LocalFileEngine( './db.stormdb ');const db = new StormDB( engine);StormDB is designed to be flexible, and can be used in NodeJS, the browser or even Electron with very small adaptations to the code. Examples usages can be seen below:.Engine APIFor expanding functionality, each database initialized can be expanded with the following options, in the format new Engine(path, options). serialize - function to serialize data before writing it to the database. deserialize - function to deserialize data from the database.Database Operations ExamplesChange Value of Key in Database.

Decibel Conversion CalculatorDecibels are defined as ten times the logof a power ratio. Decibels convert multiplication and divisioncalculations into simple addition and subtraction operations.This calculator converts between decibels,voltage gain (or current), and power gain. Just fill in one fieldand the calculator will convert the other two fields.
Equations:dB= 20log(V1/V2)= 10log(P1/P2) Decibels (dB)Voltage GainPower GainThe dBm is a logarithmic measure of power compared to 1mW.It can be converted to a voltage, if the load isknown. Typically the load is 50 ohms.
Equations:dBm= 10log(p1/.001)Load= ohmsdBmPower(Watts)Voltage DCVp of Sinusoid.
