months (or years!). While the backup may appear to have succeeded, how can you be sure until you actually restore it In this chapter, we begin with an overview of the various types of backups that can be performed with SQL Server before we look at database recovery models. We then move on to cover online piecemeal restores, expanding on the previous chapter s coverage of filegroups. We then explore the benefits of database snapshots, and we conclude with a new backup feature introduced in SQL Server 2008: backup compression.

OCR using Tesseract in C# - C# Corner
Dec 18, 2018 · In this article I am going to show how to do OCR using Tesseract in C#.

In the if statements, the value of num is ANDed with 1 If bit zero in num is set, the result of num & 1 is 1; otherwise, the result is zero Therefore, the if statement can succeed only when the number is odd You can use the bit-testing capability of the bitwise & to create a program that uses the bitwise & to show the bits of a byte value in binary format Here is one approach:

// Display the bits within a byte using System; class ShowBits { static void Main() { int t; byte val; val = 123; for(t=128; t > 0; t = t/2) { if((val & t) != 0) ConsoleWrite("1 ");

Unless you re a DBA, you d probably define a database backup as a complete copy of a database at a given point in time. While that s one type of database backup, there are many others. Consider a multi-terabyte database that s used 24/7: How long does the backup take, and what impact does it have on users Where are the backups stored, and what is the media cost How much of the database changes each day If the database failed partway through the day, how much data would be lost if the only recovery point was the previous night s backup In considering these questions, particularly for large databases with high transaction rates, we soon realize that simplistic backup strategies limited to full nightly backups are insufficient for a number of reasons, not the least of which is the potential for data loss. Let s consider the different types of backups in SQL Server.

if((val & t) == 0) ConsoleWrite("0 "); } } }

The output is shown here:

0 1 1 1 1 0 1 1

There are many tools and techniques for performing database backups, including various third-party products and database maintenance plans (covered in chapter 14). For the purposes of the examples throughout this chapter, we ll use a T-SQL script approach.

The for loop successively tests each bit in val, using the bitwise AND, to determine if it is on or off If the bit is on, the digit 1 is displayed; otherwise, 0 is displayed The bitwise OR can be used to turn bits on Any bit that is set to 1 in either operand will cause the corresponding bit in the variable to be set to 1 For example 1101 0011 | 1010 1010 -------------------1111 1011 You can make use of the OR to change the make-even program shown earlier into a make-odd program, as shown here:
