The repository is written for the following purposes.
| Terminology | definition |
|---|---|
Annotation | A type of metadata that can be added to Java source code |
API | Application Programming Interface, an interface that allows you to control the functions provided by the operating system or programming language so that it can be used in the application |
Architecture | The relationship between each element and the characteristics and elements of the system with the structure and structure of the system |
Class | The framework consisting of a state (member variable) and a method (member variable) for defining objects |
CSS | Cascading Style Sheet, a language used to separate the appearance (design) of a document represented by the contents of the document and the layout, font and visual elements |
Cursor | After querying multiple rows at the table, the database object used to handle the row, which is the result of the query, |
DCL | Double Checked Locking, a technique for implementing a safe Singleton pattern in multi -thread environment. Programming techniques that require two tests to ensure that they do not enter the sync block when the instance is already generated |
Encapsulation | Programming attribute to hide and hide some of the actual implementation of the object and the actual implementation of the object and the actual implementation. |
Factory | An object creation design pattern that allows you to create an instance of a class in the subclass |
GC | Garbage Collector, Tools that play a role in efficiently managing (deletion) of data remaining in heap memory |
Glue | Code code that is hardly combined between code code, which is difficult to modify and test |
Index | Database object with location information of data that manages rowid information of data in separate segments |
Inheritance | Object -oriented properties inherited by one class inherited and used in other classes (data, functions) |
Instance | Templates such as abstracting concepts or class objects, computer processes, etc. are actually implemented |
JDK | Java Development Kit, Java SE, Java EE, or Java ME platform is implemented, and developing tools provided by Oracle products to Solaris, Linux, Mac OS X, or Windows Java developers as binary products by Oracle products. |
JNI | Programming frameworks that can be called or called by libraries implemented in Java Native Interface, Java Code running on Java Virtual Machine (especially Hardware and Operating System Platform) and other languages such as hardware and operating system platforms, C, C ++ and Audblis. |
JS | Interpreter type programming or script language created by Netscape |
JSP | A language that inserts a Java code into the html, dynamically creates a web page on a web server and returns it to a web browser |
JVM | Java Virtual Machine, Java's source code is converted into a byte code. |
Log | Text to track the problems that occur during program development or operation or to monitor the operation status |
Modularity | Codes with similar functions should be included in the same unit program code, and other functions are developed as separate independent unit codes, so that they should be developed to easily reuse these codes in maintenance and other programs. |
OOP | Object-Oriented Promgraming, a programming paradigm to identify as a meeting of multiple independent units, "objects", out of view of the computer program as a list of instructions. |
Optimizer | The core engine of DBMS that explores the executable plan that can be handled by the user inquiries and estimates the cost of each execution plan and establishes the best execution plan. |
OS | Operating System, system software that provides hardware abstract platform and common system service to run application software as well as operating system hardware |
Overloding | It has the same function name, but the characteristics of parameters, return types, etc. |
Overriding | Programming techniques that provide subclasses or child classes in object -oriented programming to implement methods already provided by one of their superclasses or parent classes in a specific form. |
Package | It can be included in a class or interface, and the classes related to each other are divided into group units to facilitate class management. |
Platform | Hardware architecture or software framework with software. In general, the concept comprising computer architecture, operating system (OS), program language, and related runtime libraries or GUI |
Polymorphism | Programming attributes that can comment on several types of objects in one type in multiple types of objects. |
Procedure | A set of queries to run a series of queries like a function |
Prototype | Design patterns that make the types of objects to be determined from the prototype, and the instance clones themselves to create a new object |
Serialization | The process of converting data structure or object status to the same or other computer environment and to format that can be reconstructed later |
Servlet | Server -side program or its specifications that use Java to create a web page dynamically |
Singleton | Even if the constructor is called several times, the actual object is actually created, and the constructor called after the initial creation is a design pattern that returns the object generated by the first constructor |
Spring Framework | Open Source Application Framework for Java Platform, which provides various services for developing dynamic websites |
SQL | Programming language designed to manage data from the Structured Query Language |
Synonym | It refers to aliases to an oracle object (table, view, sequence, procedure), and in fact, it is a direct reference to the object, not the object itself. |
Thread-Safe | In multi -thread programming, any function, variable, or object usually has no problem in execution of the program even if it is approached simultaneously from multiple threads. |
Transaction | Unit for unavoidable work processing used in systems such as a database |
Trigger | Tasks that are automatically executed in response to events for tables |
XML | Extensible Markup Language, a multipurpose markup language recommended to create a markup language with a different purpose |
IaaS(Infrastructure as a Service) | Use a virtualization technology that has better H/W scalability, flexible and faster than conventional server hosting to provide IASS, which is the basis of PaaS and SaaS as a service. |
PaaS(Platform as a Service) | It provides a stable platform that can develop a service and an API that can develop an application that uses the environment |
SaaS(Software as a Service) | Provides applications that operate in the Cloud environment in the form of service |
