 ## Our customer's asked:
 
-Our client needs to complete a calculation when there are multiple data sources generating data at high frequencies: a calculation task is performed only when all the data from all the data sources have arrived, then send computed result to the next processing session,  otherwise, keeps waiting data. 
+Our client needs to perform a calculation in an environment where high frequency data generation occurs from multiple data sources. A calculation is only performed when data from all the sources has arrived. After calculation, the computed result is sent to the next processing session, and the whole process repeats. 
 
-Usually, our business logic code intrudes on the collection of heterogeneous data from multiple sources, multi-threading, concurrency and computation caching, which prevents us from concentrating on abstracting and describing the abstraction：
+Traditionally, in a scenario where heterogenous data from multiple data sources is collected, developers face several issues related to multi-threading, concurrency, race, locking, cache, among other things. As a result, instead of abstraction and implementation, developers spend time fixing issues. YoMo solves that below:
