this question has answer here: why isn't size of array parameter same within main? 13 answers is possible find out size of array in function without passing argument of size? this: #include <stdio.h> int length(const char* array) { int r=sizeof(array); return r; } int main() { const char array[]="www.google.com"; int a; a=length(array); printf("%d\n",a); return 0; } here result 8. you can't that, have read sizeof operator, in program it's returning size of pointer, equivalent sizeof(char *) . you can length of string using strlen() , function requires array terminated special value '\0' , means use +1 bytes store string.

i designing new hadoop-based data warehouse using hive , wondering whether classic star/snowflake schemas still "standard" in context. big data systems embrace redundancy normalized schemas have poor performance (for example, in nosql databases hbase or cassandra). is still best practice making star-schema data warehouses hive? is better designing row-wide (reduntant) tables, exploiting new columnar file formats? when designing nosql databases tend optimize specific query preprocessing parts of query , store denormalized copy of data (albeit denormalized in query-specific way). the star schema, on other hand, all-purpose denormalization that's appropriate. when you're planning on using hive, you're not using optimization general-purposefullness (?) of sql , such, i'd imagine star schema still appropriate. nosql db non-sql interface, however, i'd suggest use more query-specific design.
