A PC with a Pentium processor with a clock speed of at least 100MHz 128MB of RAM A CD-ROM drive A hard disk drive These are minimum standards, and apply to a network server on which Concordance will be installed. As of this writing, clock speeds of PCs sold by leading manufacturers can exceed 3.0GHz, and servers can be configured to have several gigabytes of RAM. With regard to hard drive space, more is better. In terms of budgeting, a database administrator should set aside at least $3,000 for a simple network server to store Concordance data files. More expensive network servers exist. Consultation with a qualified member of a firm s IT staff is recommended. The hardware requirements per client are similar to those of the minimum standards of the networked server; that is, a Pentium 100MHz or better CPU, and a minimum of 128MB of RAM, although 256MB of RAM is recommended. In practice, the more RAM an administrator can install in a client PC, the better. The reason for this is the way in which Concordance clients communicate with the networked server. When a user asks a question of a Concordance database, it is the client not the server that does the filtering and sorting. This means that all records are transferred across a network from the server to the client, and then the client PC does the work of selecting records. For mid- to large-sized databases, with hundreds of thousands or millions of rows, 256MB of RAM is inadequate.

Listing 9-16 showed an example of using a subquery in a FROM clause. We could have written the same query with a slightly different syntax, as shown in Listing 9-17. This construct is called a factored subquery (or subquery factoring). Listing 9-17. WITH Clause Example WITH g AS (select x.deptno , avg(x.msal) avg_sal from employees x group by x.deptno) select e.ename, e.init, e.msal from employees e join g using (deptno) where e.msal > g.avg_sal; ENAME -------ALLEN JONES BLAKE SCOTT KING FORD INIT MSAL ----- -------JAM 1600 JM 2975 R 2850 SCJ 3000 CC 5000 MG 3000

As you can see, we have isolated the subquery definition, in lines 1 through 5, from the actual query in lines 6 through 10. This makes the structure of the main query clearer. Using the WITH clause syntax becomes even more attractive if you refer multiple times to the same subquery from the main query. You can define as many subqueries as you like in a single WITH clause, separated by commas.

Page count: Sometimes, it isn t known just how many individual images are represented by a document range defined by a Concordance query. Opticon can calculate the total number of pages contained in a document range. Clicking the Page Count button causes Opticon to add up the total number of pages in each document and to display a sum in the text field. List: The List button launches an Open dialog. You use the dialog to select a valid Opticon print file. You use this option to print specific images listed in a properly structured, comma-delimited ASCII digital file. The format of the print file is as follows: db,ik,pages,redlines,reserved,upper_left,upper_right, lower_left,lower_right,paper_source,extra_text Each entry is defined as follows: db (database): The full path to the imagebase, including any drive letter or Universal Naming Convention (UNC) mapping, excluding extension. ik (image key): The image key as it appears in the Concordance imagebase. pages: The number of pages to print, including this image. Normally you can set this value to 1 if you remember to specify each page in the list file. reserved: Don t specify anything for this value. upper_left: Specifies the text to insert in the upper left corner of the image. upper_right: Specifies the text to insert in the upper right corner of the image. lower_left: Specifies the text to insert in the lower left corner of the image. lower_right: Specifies the text to insert in the lower right corner of the image. paper_source: Specifies the driver-dependent paper tray. extra text: The text to be included on the extra sheet.
