سپاسگزارم دوست عزیز.
سلام
دوستان let بیشتر چه معنا میاد؟
مثلا
Let A and B be two accounts that are accessed by transactions T1
and T2
حالا اگر معنی هم کنید(لطفا) که بفهمم چی به چی هست . یعنی فهمم این کلمه وقتی میاد جمله ایا تغیر میکند؟
ممنون میشم
بچه ها معنی این چند جمله چی هست؟
The project sponsor is an individual high enough in the organization to have
power over the functional managers you’ll deal with on your project. In such situations, politics may
impede progress. On the other hand, when done correctly and ethically, politics
may also facilitate progress. Building positive, supportive working relationships
with your stakeholders is an example of a positive aspect of politics.
The point of the project sponsor is to grant you the authority to act on his or
her behalf to make sure the project gets the care and feeding it needs. This
person assigns to you a level of autonomy to get the project done. If there are
problems between you and the functional managers, the project team, or
even stakeholders, the project sponsor should come to your defense. Really !
Occasionally it Stores data of individual views (materialized views), computed from generic data, if performance justification exists for such redundancy. It balances all the external views' performance requirements, possibly conflicting in an attempt to optimize overall performance across all activities.

A و B را {اطلاعات/رکوردهای مربوط به} دو حساب در نظر بگیرید که توسط تراکنش‌های T1 و T2 مورد دستیابی قرار گرفته‌اند.

troubleshooting and repairing device drivers
Device drivers can cause problems, conflict,s and instabilities with Windows. This is just
something we’ve become accustomed to over the years. The driver creation model used for
Windows 8, however, is by far the most robust in the life of the OS and, as such, it is only
poorly written drivers that cause problems and issues. Despite this reliability and robustness,
however, many IT departments like to soak test drivers on an isolated machine before deploying them.
One of the reasons why this is a good idea, assuming you even have a spare machine
available, is that even drivers that come through Microsoft’s Windows Update service aren’t
immune and can cause blue screens or instabilities, and this is something I’ve seen several
times on my own computers.
I’m a great fan of the motto “if it ain’t broke, don’t fix it” and when a driver works, there’s
no need to update it, certainly not manually. Let’s spend a little time though looking at how
we can repair drivers if something does go wrong.

Thus,we
have arrived at a state where neither of these transactions can ever proceed with
its normal execution.

بنابراین، به حالتی رسیده‌ایم که در آن هیچ یک از این تراکنش‌ها دیگر نمی‌توانند به اجرای عادی خود ادامه دهند.
دوستان دیگر ببخشند، به شخصه نمی‌رسم متون طولانی رو ترجمه کنم.

سلام
این قسمت پر رنگ رو میشه ترجمه کنید؟ متن بیشتر گذاشتم برای فهم بیشتر
میخواهم ببینم منظورش چی هست؟>
The point in the schedule where the transaction has
obtained its final lock (the end of its growing phase) is called the lock point of
the transaction. Now, transactions can be ordered according to their lock points—
this ordering is, in fact, a serializability ordering for the transactions.
درود بر دوستان
strict two-phase locking
rigorous two-phase locking
دوستان این دو کلمه به معنای سخت هست. فرق شان چیست؟
