Firstlogic's Global Data Quality Connector is integrated at the BASIS layer and communicates with the SAP Applications via TCP/IP leveraging SAP's Remote Function Call (RFC) interface. As users make postal validation inquiries in either batch or real-time, calls are made outside of the SAP Application to Firstlogic's RFC Server. Once the customer's address has been received by Firstlogic's technology, our Information Quality Suite parses, standardizes, and corrects records according to configurable business rules and local postal authority standards. To ensure your customer view is optimized, Firstlogic's technology catches duplicates at the point of entry; not after redundant information has infected your SAP Environment. Before any customer, vendor, or business partner is committed to the database, Firstlogic's Information Quality suite will immediately inspect the data upon input. The connector scans the entire database for duplicates and assigns a similarity match score to potential duplicates. At that point, the user can determine whether the entered record is unique or a duplicate that should be eliminated from the system. In addition, convenient Error Tolerant Searching is available for prompt and precise address recognition. This improves transaction processing, saves time locating records, and optimizes system efficiency.

The SCAN operation scans a character string (base string) contained in factor 2 for a substring (compare string) contained in factor 1. The scan begins at a specified location contained in factor 2 and continues for the length of the compare string which is specified in factor 1.The result field contains the numeric value of the leftmost position of the compare string in the base string.
The CHECK operation verifies that each character in the base string (factor 2) is among the characters indicated in the comparator string (factor 1). Verifying begins at the leftmost character of factor 2 and continues character by character, from left to right. Each character of the base string is compared with the characters of factor 1. If a match for a character in factor 2 exists in factor 1, the next base string character is verified. If a match is not found, an integer value is placed in the result field to indicate the position of the incorrect character.

No indexes, table scans, missing or out of date statistics, blocking, excess recompilations of stored procedures, procedures and triggers without SET NOCOUNT ON, poorly written query with unnecessarily complicated joins, too much normalization, excess usage of cursors and temporary tables.

Some of the tools/ways that help you troubleshooting performance problems are: SET SHOWPLAN_ALL ON, SET SHOWPLAN_TEXT ON, SET STATISTICS IO ON, SQL Server Profiler, Windows NT /2000 Performance monitor, Graphical execution plan in Query Analyzer.

Stereotactic radiosurgery is the very precise delivery of radiation to a brain tumor while sparing the surrounding normal brain tissue. Because it is so precise, stereotactic radiosurgery allows a higher dose of radiation to be given with more sparing of normal brain than can be achieved with conventional radiotherapy techniques.Information from MRI and/or CT scans are directly transferred to the treatment planning computer system to create a 3-D model of the tumor and surrounding normal brain. A complex radiation delivery planning system is utilized to target a high dose of radiation at the tumor while greatly limiting the dose to nearby normal brain. Special devices are used to keep the head still so that the radiation will be aimed with great accuracy at the targeted tumor.
