The EF is essentially an O/R mapping tool. It takes care of object persistence for you. In other words, it acts as your data layer. writing applications using entity framework saves lot of development time and its good..if we are developing enterprise applications, we need to think about performance..all in all its good for small applications..
- Advantages : One common syntax ( LINQ / Yoda ) for all object queries whether it is database or not , Pretty fast if used as intended , easy to implement SoC , less coding required to accomplish complex tasks
Disadvantages : you have to think in a non traditional way of handling data , not available for every database - Disadvantage: If there is any schema change in database FE won’t work!!! You have to update the schema in solution as well!!!
Advantage: Its fast and straight forward using LINQ/FE objects For Add/Modify/Delete/Update. - Advantages:-Easy to map business objects (with drag & drop tables on environment).
-It keeps a good performance when you work with a small / middle domain model.
Disadvantages:-It's limited when you work with a huge domain model.
-Scalability.
