For example, if a table contained employees and their titles, and more than one employee could have the same title (very likely), a key that uniquely identified employees wouldn t uniquely identify titles, so the titles wouldn t be functionally dependent on a key of the table To put the table into 2NF, you d create a separate table for titles with its own unique key and replace the title in the original table with a foreign key to the new table Note how this reduces data redundancy The titles themselves now appear only once in the database Only their keys appear in other tables, and key data isn t considered redundant (though, of course, it requires columns in other tables and data storage)..

To reduce this impact on performance within the Memory Management Unit (MMU) located on the CPU, a table exists with its own private memory the TLB Every request for data goes to the MMU, where the TLB maps the virtual memory addresses to the physical memory addresses based on the tables set up in the TLB These tables are populated by the kernel according to the most recent memory locations accessed If the page table entries are not located in the TLB, then the information must still be fetched from the page tables in main memory Therefore, it s advantageous to ensure that highest number of memory references possible can be satisfied from the TLB The TLB capacity is usually small, and the standard page size on an x86 and x86-64 Linux system is 4KB.

Thus, the large amount of memory required by Oracle means that most accesses will not be satisfied from the TLB, resulting in lower-than-optimal performance Oracle uses a large amount of contiguous memory, so the references to this memory could more efficiently managed by mapping a smaller number of larger pages For this reason, on Linux systems implementing the 26 kernel, Oracle 11g can take advantage of a huge TLB pool You will learn how to configure these huge pages, which we strongly recommend using, in 6 When correctly implemented, huge pages increase the likelihood that an Oracle memory access will be satisfied from the TLB This stands in contrast to traversing a number of physical memory locations to discover the desired memory address This approach also saves CPU cycles that would otherwise be spent managing a large number of small pages.

Save and Read PDF File Using SQL Server and C# - C# Corner
12 Feb 2013 ... In this article we will show how to save a PDF file in a database .

_NameParam.Direction = ParameterDirection.Input; _NameParam.Value = txtProductName.Text; _cmdObj.Parameters.Add(_NameParam); _cmdObj.ExecuteNonQuery(); MessageBox.Show("Updating done!"); _connObj.Close(); _connObj.Dispose(); _connObj = null; } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } Run the form, and specify the name of an existing product in the Products table in the first text box. Specify an increment value in the numeric control, and click the Update Now! button. Upon successful execution, run a SELECT statement in SQL*Plus to check the price of the product you ve just updated. You should see it incremented by the amount you keyed in earlier.

Third normal form (3NF) extends the concept of functional dependence to full functional dependence. Essentially, this means that all nonkey columns in a table are uniquely identified by the whole, not just part of, the primary key. For example, if you revised our hypothetical 1NF managers-employees table to have three columns (managername, employeeid, and employeename) instead of two, and you defined the composite primary key as managername + employeeid, the table would be in 2NF (since employeename, the nonkey column, is dependent on the primary key), but it wouldn t be in 3NF since employeename is uniquely identified by part of the primary key (employeeid). Creating a separate table for employees and removing employeename from managers-employees would put the table into 3NF. Note that even though this table is now normalized to 3NF, the database design is still not as normalized as it should be. Creating another table for managers, using an ID shorter than the manager s name, though not required for normalization here, is definitely a better approach that would probably be advisable for a real-world database. Database design (even of small databases) is an art more than a science, and applying normalization wisely is always important. On the other hand, normalization inherently increases the number of tables and therefore the number of operations (called joins) required to retrieve data. Denormalizing one or more tables, by intentionally providing redundant data to reduce the number or complexity of joins to get quicker query response times, may be necessary. With either normalization or denormalization, the goal is to control redundancy so that the database design adequately (and ideally, optimally) supports the actual use of the database.
