Denis Database

Denis Database is a Java Library that works with Redis logic and has a simple structure. It provides ease of access and manipulation of temporary data by storing operations in the cache. It increases database categorization with action statuses, providing ease of development.

Actions

actString Class

actString is a class designed to manage data with a String key and String value pair. This class is used for basic CRUD operations and checking data existence.

Methods

Method Return Type Description
set(String key, String value) Void Saves or updates the specified key and value.
get(String key) String Returns the value corresponding to the given key. Returns null if no value exists.
del(String key) Void Deletes the specified key and its value.
exists(String key) Boolean Checks whether the given key exists.

Usage Example

actString actstr = new actString();

// Adding data
actstr.set("key1", "value1");

// Retrieving data
String value = actstr.get("key1"); // "value1"

// Data check
boolean exists = actstr.exists("key1"); // true

// Deleting data
actstr.del("key1");

actListrig Class

actListrig is a structure that associates a List<String> key with a String value. It is created using ConcurrentHashMap, which is suitable for parallel operations.

Methods

Method Return Type Description
set(List<String> key, String value) Void Saves or updates the specified list key and value pair.
get(List<String> key) String Returns the value corresponding to the given list key. Returns "null" if no value exists.
del(List<String> key) Void Deletes the specified list key and its value.
exists(String key) Boolean Checks whether the given list key exists.
getStore() ConcurrentHashMap Returns all data.

Usage Example

import java.util.Arrays;
import java.util.List;

actListrig actlist = new actListrig();

// Create key
List<String> key = Arrays.asList("item1", "item2");

// Add data
actlist.set(key, "value1");

// Retrieve data
String value = actlist.get(key); // "value1"

// Data check
boolean exists = actlist.getStore().containsKey(key); // true

// Delete data
actlist.del(key);

Class Differences and Usage Scenarios

Feature actString actListrig
Key Type String List<String>
Data Management Single key-value pair Managing multiple keys together
Use Case Managing simple structures Managing complex, hierarchical structures

Example Scenarios:

  • actString can be used to store username-password pairs in a database.
  • actListrig can be used to associate product categories and subcategories on an e-commerce site.

actStrist Class

actStrist is a class that associates a String key with a List<String> value. It uses the ConcurrentHashMap infrastructure suitable for parallel operations. This class is designed to bind multiple values to a single key.

Methods

Method Return Type Description
set(String key, List<String> value) Void Saves or updates the specified key and value list.
get(String key) List<String> Returns the value list corresponding to the given key. Returns ["null"] if no value exists.
del(String key) Void Deletes the specified key and its value list.
exists(String key) Boolean Checks whether the given key exists.
getStore() ConcurrentHashMap Returns all data.

Usage Example

actStrist actstrist = new actStrist();

// Create key and value list
String key = "group1";
List<String> values = Arrays.asList("item1", "item2", "item3");

// Add data
actstrist.set(key, values);

// Retrieve data
List<String> retrievedValues = actstrist.get(key);
System.out.println(retrievedValues); // [item1, item2, item3]

// Data check
boolean exists = actstrist.exists(key);
System.out.println(exists); // true

// Delete data
actstrist.del(key);

// Check again
exists = actstrist.exists(key);
System.out.println(exists); // false
