Native Queries for Persistent Objects A Design White Paper
Short Description
Most persistence architectures for Java and .NET provide interfaces to execute queries written in an architecture-specific query language. These interfaces are string based: queries are defined in strings that are passed to the persistence engine for interpretation. String-based query interfaces have significant negative impact on programmer pro- ductivity. The queries are not accessible to development environment features like compile-time type checking, auto-completion, and refactoring. Programmers must work in two languages: the implementation language and the query language. This paper introduces Native Queries, a concise and type-safe way to express queries directly as Java and C# methods. We describe the design of Native Queries and provide an overview of implementation and optimization issues. The paper also includes a discussion of the advantages and disadvantages of the current design of Native Queries.

MySQL and Java
Short Description
In this section we will create a new database, a new user, and a very simple table. MySQL has a two level directory like hierarchy for keeping databases and tables. At the root there is MySQL; under root you can only create “databases.” Database is almost like a directory, you can create “tables” under a database.

Tutorial for MySQL An Introduction to Java Programming
Short Description
The mysql database contains the tables that store the information about the server and its users. This database is intended for the server administrator to use. For example, the administrator can use it to create users and grant or revoke user privileges. Since you are the owner of the server installed on your system, you have full access to the mysql database. However, you should not create user tables in the mysql database.

Using generic Java threads on JStamp/JStik/SaJe
Short Description
- A thread is a path of program execution.
- Multi-threaded programming is one of the most powerful features of Java. Applied inappropriately, it can lead to an infinite number of difficult to diagnose bugs, and unpredictable program behavior.

C# Versus Java
Short Description
Microsoft describes C# (”C sharp”) as a “simple, modern, object-oriented, and type-safe programming language derived from C and C++.” That statement would apply equally well to Java. In fact, after comparing the two languages, it’s obvious that prerelease descriptions of C# resemble Java more than C++. As Example 1 illustrates, the language features and syntax are similar. Example 1(a) is the canonical “Hello World” program in Java, while Example 1(b) is the program in C#.

An ASM specification of C# threads and the .NET memory model
Short Description
Abstract. We present a high-level ASM model of C# threads and the .NET memory model. We focus on purely managed, fully portable threading features of C#. The sequential model interleaves the computation steps of the currently running threads and is suitable for uniprocessors. The parallel model addresses problems of true concurrency on multiprocessor systems. The models provide a sound basis for the development of multi-threaded applications in C#.

Threading in Java and C# A Focused Language Comparison Overview
Short Description
Both Java and .NET have built-in support for threads. In Java, this support is in three main forms: a mutex variable is associated with every object; there is a set of methods defined on Object that support coordination of threads; and a set of classes in java.lang that allows programmers to create and manage threads. Similarly, in .NET there is a Monitor (or lock) associated with every object instance. The System.Threading namespace contains classes that allow thread creation and manipulation.
