THE SMALL BINARY INDEX SPEED | |
| In database application we normally retrieve data using indexes. Most valuable are small indexes, especially in LAN applications, where the indexes data travel over the wire. We present an example of table’s data distribution on which the small binary index is significantly slower than others. | ||

VFP PERFORMANCE IN LAN ENVIRONMENT | |
| Visual FoxPro is one the fastest performing desktop and LAN-based database management system available today. But opening large tables creates a great deal of network traffic. This can be a substantial delay, sometimes beyond an acceptable length of time. In this article I present the results of the VFP speed measurement in the process of acquiring database data with different VFP9 methods. The store procedures, duplicated records and unique indexes enriched by the programmers' knowledge of the database organization can speed up the data query. With the stored procedure we can fetches the result set of 100 records from the server about 100% faster than with the full optimized SQL command. Changing the table's normalization and using appropriate indexes, we can improve the retrieval time for 275%. | ||

BUILDING AN N-TIER VERSION OF THE TASTRADE DEMO APPLICATION USING FOXDATAOBJECTS – PART 1 | |
| FoxDataObjects (www.foxdataobjects.com) is an object/relational persistence and query engine for Visual FoxPro. It lets us develop persistent classes following object-oriented idiom - including association, inheritance, composition, and collections, and allows us to express queries using a simple Object Query language, as well as in native SQL. Basically the product automates the Data-Access layer of an n-Tier application, but more important, it maps our business object model to a relational model, connects our Business layer to any supported database engine and provides a simple API for object persistence and querying. In this article, Bernardo Fourcade shows you how to re-create parts of the Tasmanian Traders (Tastrade) sample application, but in an n-Tier architecture to show some basic features of FoxDataObjects. | ||
