Develop and deploy databases in Visual Studio with migration scripts.

Want to work on databases in Visual Studio alongside your application? Feeling the pain of managing and deploying database changes manually? Then ReadyRoll's the tool for you.

It generates numerically ordered SQL migration scripts that sit inside your project and take your schema from one version to the next.

You can add them to version control, use them to build and release, and automate database and application deployments, all in one process.

• String: این نوع پرکاربردترین نوع داده برای ذخیره اطلاعات است. رشته در MongoDB باید بصورت یونیکد (utf-8) معتبر باشد.
  
• Integer: این نوع برای ذخیره کردن یک مقدار عددی استفاده می‌شود. Integer بسته به نوع سرور می‌تواند 32 یا 64 بیت باشد.
  
• Boolean: این نوع برای ذخیره کردن یک مقدار بولی (true/false) استفاده می‌شود.
  
• Double: این نوع برای مقادیر با ممیز شناور استفاده می‌شود.
  
• کلیدهای Min/Max: این نوع برای مقایسه یک مقدار با کمترین یا بیشترین عناصر BSON استفاده می‌شود.
  
• Array: این نوع برای ذخیره آرایه‌ها یا لیست یا چندین مقدار در یک کلید استفاده می‌شود.
  
• Timestamp: این نوع می‌تواند برای ضبط زمان تغییرات (مثلا وقتی یک سند درج می‌شود یا تغییر می‌کند) مفید باشد.
  
• Object: این نوع برای سندهای توکار استفاده می‌شود.
  
• Null: این نوع برای ذخیره مقدار تهی (Null) استفاده می‌شود.
  
• Symbol: این نوع بطور یکسان برای ذخیره رشته استفاده می‌شود، اما عموما برای زبان‌هایی که از یک نوع نماد (Symbol) مشخص استفاده می‌کنند تعبیه شده است.
  
• Date: این نوع برای ذخیره تاریخ یا زمان جاری به فرمت زمان در یونیکس (UNIX) استفاده می‌شود. با ساخت یک شی از نوع Date و ارسال روز، ماه و سال به آن می‌توانید تاریخ مشخص خود را داشته باشید.
  
• Object ID: ای نوع برای ذخیره سازی شناسه سند استفاه می‌شود.
  
• Binary Data: این نوع برای ذخیره سازی داده باینری استفاده می‌شود.
  
• Code: این نوع برای ذخیره سازی کد جاوا اسکریپت داخل سند استفاده می‌شود.
  
• Regular Expression: این نوع برای ذخیره سازی عبارت باقاعده استفاده می‌شود.
