Underlaying Technology of Modern O/R Mapper
The document discusses modern object-relational mappers (ORMs) and their underlying technologies. It covers several key concepts: 1. Query objects allow building queries through method chaining rather than keyword arguments, abstracting SQL queries. 2. View-layer caching can be implemented through lazy loading to avoid tight coupling between controllers and views. 3. The N+1 problem, where queryin

Summary: Using PowerShell to identify RPC ports in use by capturing content from PowerShell We'd like to introduce you today to one of our newest bloggers! It's a froopingly awesome friend of ours, Joel Vickery, PFE. (did I mention Dr. Scripto is a big fan of books written by Douglas Adams?....oops!) Take it away Joel! Thanks Doc! So ...
Comparison of different SQL implementations
The goal of this page was to gather information relevant for people who are porting SQL from one product to another and/or are interested in possibilities and limits of 'cross-product' SQL. The following tables compare how different DBMS products handled various SQL (and related) features. If possible, the tables also stated how the implementations should do things, according to the SQL standard.
SQL Injection Attacks by Example
A customer asked that we check out his intranet site, which was used by the company's employees and customers. This was part of a larger security review, and though we'd not actually used SQL injection to penetrate a network before, we were pretty familiar with the general concepts. We were completely successful in this engagement, and wanted to recount the steps taken as an illustration. "SQL Inj
