CONCLUSION AND PROBLEM
5.1 Conclusion
I have internship at Yip In Tsoi in 4 months. The internship gave me many
experiences such as how to life in the city, how to working together as a team and the
help of my team has taught me many things. I was learning to use the various solutions. I
went to work as a .NET programmer that is responsible for the inventory management
system on the Royal Thai Air Force Headquarters. The help and advice on how to write
the code to connect to databases, modified to meet the user or business systems, logic
of writing code in different ways, learning systems business for variations also meeting
with the users to share the idea of the business to be in the right direction or after-sales
service and maintenance.
Knowledge in the classroom that used to work, it has to write code in a good
design. The commented code that could be used with our configuration documentation
such as test case, error requirement document, functional requirements specification
document (FRS), and user requirement document (URD) which covers learned a lot .
Finally, the work required to successfully work as a team. Good team work will
lead to a breakthrough for reliable customers to get quality work together to build a good
relationship in the future.
5.2 Problems
My internship uses the C# .NET, ASP.NET and Oracle for the database, which
I had never used before. I need to train with the company but it is a language pattern in
Object oriented for apply from the class. Also the oracle is the same MySQL script to
query the values out that make I learn to apply. Most solutions to solve the business
system in which to learn and adapt as well.
