compression offered a way to deal with rapid data growth, but it required bulk inserts or direct loads to compress data and did not work on large objects and some user defined data types. Targets for compression were tables, table partitions, and materialized views. The compression feature extended the index compression that was already part of the RDBMS kernel. The easiest ways to use compression in data warehousing was to use the SQL loader command-line tool for direct path loads or to reorganize objects using CREATE TABLE AS SELECT statements. Alternatively, data could be inserted either in parallel with the APPEND hint or by using DBMS_REDEFINITION to compress tables/partitions online. Compressing data in tables can save space, improve cache efficiency, and reduce I/O operations when retrieving data. However, there was an overhead associated with the compression and decompression of the data blocks. Oracle 11g lifted many restrictions in the advanced compression option, making compression useful for OLTP workloads by introducing support for insert and update operations. Instead of being compressed when filled, blocks are now compressed in batch operations to minimize the impact on the system.

You should see the File uploaded! message shown in Figure 4-18.

Note Advanced compression offers far more than table compression. For example, it allows for Secure File deduplication and compression, Data Pump compression, and the compression of the redo stream in Data Guard, topics that are outside the scope of this book.

To retrieve BLOB data, you can use the OracleBlob class to retrieve the byte array for that data that you are after. Create a new form, and place a text box for the user to type in the Product ID as well as button next to it called Get BLOB. Place an enlarged PictureBox control at the bottom. The idea is to let the user retrieve the file attachment (an image is assumed to be uploaded earlier) for the specified Product ID and to then display it in the picture box control. The code to do this is shown in Listing 4-19. Listing 4-19. Retrieving BLOB Data

Most of these features can simply be implemented by the database administrator. In the case of third-party applications, however, it is important to confirm with the vendor that the application will be still supported if you use them.

There are some pitfalls you must avoid when developing applications in RAC. Let s ignore unsuitable and non-scalable hardware for the moment, and look at some other causes for this. For example, poor application design contributes massively to poor scalability. The following paragraphs list some common problems that should be avoided. Many developers are taught object oriented-programming languages such as Java or C#, which allow designers to develop abstract base types and use features such as inheritance to subclass these

7. Run the code with Ctrl+F5, and you should see the result shown in Figure 9-2.

types for their individual needs The object-oriented approach to developing needs to be translated into the relational model when using a database as a backend There are many frameworks available to perform this task, but many of these tend to be generic in nature, and typically they don t fully support the capabilities of a modern database management system In fact, many frameworks use the database as little more than a glorified file system, which makes tuning applications based on these frameworks difficult When developing applications for the Oracle database, it is important to pay attention to schema design Oracle offers a wealth of data and segment types to choose from, depending upon usage requirements Suboptimal schema design can cause queries to be expensive or to use lots of physical and logical I/Os, which ultimately hampers scalability As a rule of thumb, the application schema should be normalized.
