New rows are added with a value of N to signify not processed, and as they are processed, they are updated to Y to signify processed We would like to index this column to be able to retrieve the N records rapidly, but there are millions of rows and almost all of them are going to have a value of Y The resulting B*Tree index will be large, and the cost of maintaining it as we update from N to Y will be high This table sounds like a candidate for a bitmap index (this is low cardinality, after all!), but this is a transactional system and lots of people will be inserting records at the same time with the processed column set to N and, as we discussed earlier, bitmaps are not good for concurrent modifications. c# pdf viewer without adobe: C# PDF : PDF Document Viewer & Reader SDK for Windows Forms ... how to create pdf viewer in c# How to: Add a PDF Viewer to the WinForms Application via Code ...

When we factor in the constant updating of N to Y in this table as well, then bitmaps would be out of the question, as this process would serialize entirely So, what we would really like is to index only the records of interest (the N records) We ll see how to do this with function-based indexes, but before we do, let s see what happens if we just use a regular index Using the standard BIG_TABLE script described in the setup, we ll update the TEMPORARY column, flipping the Ys to Ns and the Ns to Ys:. adobe pdf reader c# Pdf Viewer in ASP . net - CodeProject

Rating 4.8 Relational databases have been an integral part of enterprise development for a few decades now. The fact that these business data storage mainstays are backed by their own body of mathematical theory (relational algebra) speaks to the elegance and robustness of this mature technology. E. F. Codd first introduced the theory of relational databases in 1970 while working at IBM. This groundbreaking research eventually led to the creation of today s database products, including IBM s own highly successful DB2 database. Oracle is the most popular database in existence today, in vibrant competition with products like Microsoft SQL Server, Sybase, MySQL, and many others, in addition to IBM s DB2. Fundamentally, relational databases store and organize related data into a hierarchy of schemas, tables, columns, and rows. Other types of databases exist, including flat-file, hierarchical, network, and object-oriented databases. Each of these is worthy of study on its own merits. However, the EJB 3 specification only supports relational databases, and that will be where we draw the line with regard to the database discussions in this book. The focus of this appendix is to briefly discuss each of the relational concepts. ops$tkyte@ORA10G> update big_table set temporary = decode(temporary,'N','Y','N'); 1000000 rows updated. And we ll check out the ratio of Ys to Ns: ops$tkyte@ORA10G> select temporary, cnt, 2 round( (ratio_to_report(cnt) over ()) * 100, 2 ) rtr 3 from ( 4 select temporary, count(*) cnt 5 from big_table 6 group by temporary 7 ) 8 / T CNT RTR - ---------- ---------N 1779 .18 Y 998221 99.82 As we can see, of the 1,000,000 records in the table, only about one-fifth of 1 percent of the data should be indexed. If we use a conventional index on the TEMPORARY column (which is playing the role of the PROCESSED_FLAG column in this example), we would discover that the index has 1,000,000 entries, consumes over 14MB of space, and has a height of 3: ops$tkyte@ORA10G> create index processed_flag_idx 2 on big_table(temporary); Index created. ops$tkyte@ORA10G> analyze index processed_flag_idx 2 validate structure; Index analyzed. ops$tkyte@ORA10G> select name, btree_space, lf_rows, height 2 from index_stats; NAME BTREE_SPACE LF_ROWS HEIGHT ------------------------------ ----------- ---------- ---------PROCESSED_FLAG_IDX 14528892 1000000 3 Any retrieval via this index would incur three I/Os to get to the leaf blocks. This index is not only wide, but also tall. To get the first unprocessed record, we will have to perform at least four I/Os (three against the index and one against the table). How can we change all of this We need to make it so the index is much smaller and easier to maintain (with less runtime overhead during the updates). Enter the function-based index, which allows us to simply write a function that returns NULL when we don t want to index a given row and returns a non-NULL value when we do. For example, since we are interested just in the N records, let s index just those: interface BeanNameAware + setBeanName(name : String) open pdf file in new window asp.net c# A simple PDF viewer windows form - Stack Overflow
