Vs UML Class DiagramER models are focused on database structural analysis. Whereas UML class diagrams facilitate software system modeling and application development by describing classes, attributes, operations and relationships between objects.A major difference between ER and UML class diagrams is classifier notation – Entities vs Classes. While entities describe data constructs, classes define code components more from an Object-oriented perspective.However, since databases support applications enabling business functions, using both ER and class diagrams collectively can model comprehensive systems effectively.ER Diagram ToolsThere are many intuitive desktop and cloud-based ER diagram software tools available such as:LucidchartQuick Database Diagrams (DBDesignerFork) Visual Paradigm dbdiagram.ioSQLDBMCreatelyThese tools improve productivity by providing built-in ER diagram templates, relationship symbols, flowing connectors, different color themes, etc. Collaboration capabilities also allow Multiple stakeholders to provide inputs on ER models using mentions, comments or chat integration in tools like Lucidchart and Creately.According to 2022 StackOverflow survey, Lucidchart and Draw.io are the most popular ERD software used by developers. Online tools like dbdiagram,io also make ER modeling seamless with instant cloud collaboration.Notable ER Diagram UsageAs per research firm HostingTribunal, usage of ER modeling is very common across these major industries and use cases: Banking – High transaction systems like retail banking, insurance firms and investment apps leverage ER modeling extensively for mapping data flows. Ecommerce – 60% of online retail platforms model catalog, orders and logistics data with ER diagrams.Healthcare – Patient records, treatment plans and hospital administration systems model domain entities and relationships for development.Education – Student information systems, enrollment workflows use ER techniques for planning.This showcases how ER diagrams enable modeling logical data structures across diverse verticals. The simple pictorial interface facilitates less technical teams to also comprehend data systems better, enabling closed-loop feedback.Advanced Concepts in ER ModelingWe have explored ER modeling fundamentals so far. Some additional advanced concepts include:Specialization / Generalization – Enables entities and relationships to inherit attributes and cardinalities from a superclass improving reusability.Aggregation – Used when a relationship itself can be treated as an independent entity with additional attributes. Useful for statistics and analysis. For example, an ‘enrollment’ relationship containing students taking courses can have its own properties like enrollment period, status etc. beyond just connecting student and course entities.Weak Entities – Entity sets that do not contain a primary key and depend on another entity (owner) as they cannot exist independently. Converting ER Models to NoSQL databases – ER principles map well to NoSQL data stores like MongoDB providing flexibility from rigid relational structures.Denormalization and MERGE Types – To optimize heavy read model patterns, databases can be de-normalized with nested merged structures derived from base ER models.These are just few advanced ER based modeling techniques for enhancing database and application functionality.Sample ER Diagram WorkflowLet‘s briefly visualize a sample workflow for database modeling with ER diagrams:Step 1) Study business domain rigorously Step 2) Identify key entities and attributes via interviewsStep 3) Define relationships between entitiesStep 4) Map out rough initial ER diagram structure Step 5) Add granular attributes, validate cardinality relationsStep 6) Normalize entities to 3NFGoogle Diagram Io Aws Architecture Diagrams
Forepoll,kqueueandselecton GitHub. Let's take a look at the components in the diagram above with anoutline of their purpose:IO Event Queue: Single publisher, multiple consumer queue. It is therecipient of the IO events from as in epoll, kqueue, select. The events aresocket handles and the type of operation the OS has associated them with, e.g.,read or write. The IODispatcher plays the publisher role, and any number ofworker threads are the consumers.Interest Queue: Multiple publisher, single consumer queue. Worker threadspublish socket handles and operations to this queue when IO is unavailable,e.g., socket read or write returns zero. The IODispatcher will enqueue thesocket handle for more reads or writes as defined by the operation.Disconnect Queue: Multiple publisher, single consumer queue. Worker threadspublish socket handles to this queue destined to be disconnected from the serverand have their resources reused by other connections. The worker thread does notdisconnect the socket by itself because multiple threads may attempt to access adata structure that is not thread-safe.Configuring network IOWe disregarded ByteBuffer for not being an interface, so it would only be fairfor us to have interfaces in key places. One of these places is configuration,which provides IODispatcher with basics such as:The IP address of the network interfacePort to bind toBiasBuffer sizesNetwork facadeClock facadeConnection context factoryIt's necessary to explain bias here, which might not be so obvious. When the TCPconnection is first accepted, it is enqueued for IO right away. The biasprovides an expectation of the initial operation of a connection, such as reador write. For example, most TCP protocols would have 'read bias', which meansthat connecting clients will have to send data before the server repliesanything. You can probably think of a protocol that requires the server torespond first before the client sends anything - in this case, the bias will be'write'.Network & clock facades have static implementations for production runtime, butfor tests, they can be both spot-implemented to simulate OS failures and producestable timestamps.Connection ContextConnection context is a Java object that encapsulates the connection state,which is protocol-specific. It is stored together with the socket handle andmanaged by IODispatcher via the context factory. We talked a little. Draw Io Circuit Diagram .

This is also a popular interview question if you are going for two to four years of experience. Let’s understand in this way. Imagine whole human body as JDK, hands and legs as JRE and heart as JVM. Let’s see one by one.Java Development kit(JDK) – JDK stands for java development kit, is a main component which contains JRE,JVM and JIT.JDK used to develop and run the java program.Observe the below diagram, we have JRE inside JDK.Java Runtime Envirnment (JRE) – JRE contains JVM which is used to run java program.Inside JRE we have bin and lib.3. Bin folder contains different types of dll files and exe files. We can see jvm.dll here.4. Lib folder contains different jar files. One of important jar is rt.jar which contains all classes and interfaces which belongs to lang,util and io package.Java virtual machine (JVM) – JVM stands for Java Virtual Machine, is heart of java programming language.It provides interpreter and JIT.JVM converts java byte code to machine language.Just In Time Compiler(JIT) – JIT stands for just in time compiler.It instruct interpreter to execute java byte code fast. It is used to improve the performance of java program execution.Comments
