Here we use System.Uri type to parse a URL: > open System;; > System.Uri.TryCreate("http://www.thebritishmuseum.ac.uk/", UriKind.Absolute);; val it : bool * System.Uri = (true, http://www.thebritishmuseum.ac.uk/ { AbsolutePath = "/"; ... DnsSafeHost = "www.thebritishmuseum.ac.uk"; ... Port = 80; ... Scheme = "http"; }) > Uri.TryCreate("e3 %//ww.gibberish.com", UriKind.Absolute);; val it : bool * Uri = (false, null) Many .NET types are used to hold static functions such as those for converting data from one format to another. Types such as System.Random play a similar role via objects with a small amount of state. Table 10-5 shows some of the most useful of these types.

Note I used a SQL trick to generate data in this example. I wanted more than seven departments to

demonstrate that Oracle will limit the number of department keys per block based on my SIZE parameter above. Therefore, I needed more than the four department rows found in SCOTT.DEPT. I generated nine rows using the connect by level trick against DUAL and performed a Cartesian join of those nine rows with the four in DEPT resulting in 36 unique rows. I did a similar trick with EMP to fabricate data for these departments.

approach to COM interoperability The NET runtime ships with tools that allow you to generate RCW and CCW wrappers offline, which allows you to use COM components as NET classes, and vice versa These tools are as follows: tlbimpexe: This is a tool for generating an RCW of a COM component given its type library aximpexe: This is similar to tlbimpexe and supports the generation of ActiveX components2 that have graphical interfaces (and that need to be integrated with Windows Forms) tlbexpexe: This generates a COM type library describing a NET assembly The CLR will be loaded as a COM component and will generate the appropriate CCW to make NET types accessible as COM components regasmexe: This is similar to tlbexpexe It also performs the registration of the assembly as a COM component.

Now that the data is loaded, let s look at the organization of it on disk. We ll use the DBMS_ROWID package to peek into the rowid and see what blocks data is stored on. Let s first look at the DEPT table and see how many DEPT rows per block we have: ops$tkyte%ORA11GR2> select min(count(*)), max(count(*)), avg(count(*)) 2 from dept 3 group by dbms_rowid.rowid_block_number(rowid) 4 / MIN(COUNT(*)) MAX(COUNT(*)) AVG(COUNT(*)) ------------- ------------- ------------1 7 6 So, even though we loaded DEPT first and the DEPT rows are very small (hundreds of them could fit on an 8k block normally) we find that the maximum number of DEPT rows on a block in this table is only seven. That fits in with what we anticipated above when we set the SIZE to 1024. We estimated that with an 8k block and 1024 bytes of data per cluster key for the combined EMP and DEPT records, we would see approximately seven unique cluster key values per block, and that is exactly what we are seeing here. Next, let s look at the EMP and DEPT table together. We ll look at the rowids of each and compare the block numbers after joining by DEPTNO. If the block numbers are the same, we ll know that the EMP row and the DEPT row are stored on the same physical database block together if they differ we ll know they are not. In this case, we observe that all of our data is perfectly stored. There are no cases where a record for the EMP table is stored on a block separate from its corresponding DEPT record: ops$tkyte%ORA11GR2> select * 2 from ( 3 select dept_blk, emp_blk, 4 case when dept_blk <> emp_blk then '*' end flag, 5 deptno
