For example, assume there is a database table PRODUCT (PROD_ID INTEGER, PROD_DESC VARCHAR(64)) and a Java class com.example.Product (id: int, description: String).To read the product record having the key PROD_ID into a new Product POJO, the following mapping is added into an iBATIS XML mapping file:
A DataSource object has properties that can be modified when necessary. For example, if the data source is moved to a different server, the property for the server can be changed. The benefit is that because the data source's properties can be changed, any code accessing that data source does not need to be changed.
MyBatis is a Java persistence framework that couples objects with stored procedures or SQL statements using an XML descriptor or annotations. MyBatis is free software that is distributed under the Apache License 2.0. MyBatis is a fork of iBATIS 3.0 and is maintained by a team that includes the original creators of iBATIS.
The Spring Framework is an application framework and inversion of control container for the Java platform. [2] The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform.
The effective action also acts as a generating functional for one-particle irreducible correlation functions. The potential component of the effective action is called the effective potential , with the expectation value of the true vacuum being the minimum of this potential rather than the classical potential, making it important for studying ...
The convolution of a function with a Gaussian is also known as a Weierstrass transform. A Gaussian function is the wave function of the ground state of the quantum harmonic oscillator. The molecular orbitals used in computational chemistry can be linear combinations of Gaussian functions called Gaussian orbitals (see also basis set (chemistry)).
One definition sees language primarily as the mental faculty that allows humans to undertake linguistic behaviour: to learn languages and to produce and understand utterances. This definition stresses the universality of language to all humans, and it emphasizes the biological basis for the human capacity for language as a unique development of ...
In computer operating systems, memory paging is a memory management scheme that eliminates the need for contiguous memory allocation. [1]It is often combined with the related technique of allocating and freeing page frames and storing pages on and retrieving them from secondary storage [a] in order to allow the aggregate size of the address spaces to exceed the physical memory of the system.
