What is the main purpose of mapping network drives? What does "database normalization" mean? What is a foreign key in database management? What are the three primary goals of network security? Which of the following would be the most suitable for use as a primary key when storing a list...
Binary encoding is a memory-efficient encoding scheme as it uses fewer features than one-hot encoding categorical data. Further, It reduces the curse of dimensionality for data with high cardinality. Base N Encoding Before diving into BaseN encoding let’s first try to understand what is Base he...
What is the significance of 3-tier architecture when discussing the database? What is a primary key in database management? What is a foreign key in a database? Does a foreign key populate information from one table to another table? Explain. How does cardinality affect database design? Wha...
Cardinality defines thepossible number of occurrences in one entity which is associated with the number of occurrences in another. For example, ONE team has MANY players. When present in an ERD, the entity Team and Player are inter-connected with a one-to-many relationship. ...
We’ve all seen the “Error 3002: Problem in mapping fragments starting at line 46:…” errors. The error reporting on EDMX could definitely be improved, but throwing an exception from the line of code-based configuration that caused an issue is always going to be easier. We should note ...
