What is RDBMS?
RDBMS stands for Relational Database Management System. RDBMS is the basis for SQL, and for all modern database systems like MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access.
A Relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E. F. Codd.
PHP is a server-side scripting language that can be embedded into HTML pages using PHP tags. When a PHP page is requested, the server will execute any PHP code and output the results. PHP allows variables, control structures, and functions to handle tasks like form processing, file uploads, and database access. Functions like file() can read file contents into an array, and files can be uploaded and moved using the $_FILES array and move_uploaded_file() function. PHP scripts can generate dynamic web page content on the server before sending the page to the client.
Dokumen tersebut membahas konsep dasar sistem basis data meliputi pengertian database, sistem database, komponen dasar sistem database, jenis data dalam database dan hubungannya, keuntungan dan kerugian pemakaian sistem database, istilah-istilah yang dipergunakan dalam sistem basis data, serta aplikasi sistem basis data dalam lifecycle pengembangan sistem.
This document provides an introduction to databases. It defines what a database is, the steps to create one, and benefits such as fast querying and flexibility. It describes database models like hierarchical, network, entity-relationship, and relational. Key database concepts are explained, including entities, attributes, primary keys, and foreign keys. Finally, it outlines database management system components, common users, and introduces Microsoft Access.
This document discusses PHP form handling. It explains that the $_GET and $_POST variables are used to retrieve information from forms. It provides an example of a basic HTML form that sends data to a PHP file using the GET and POST methods. The differences between GET and POST are explained, including that GET values are visible in the URL while POST values are not. The document also covers validating user input and using arrays to store and check login credentials.
The document discusses data modeling, which involves creating a conceptual model of the data required for an information system. There are three types of data models - conceptual, logical, and physical. A conceptual data model describes what the system contains, a logical model describes how the system will be implemented regardless of the database, and a physical model describes the implementation using a specific database. Common elements of a data model include entities, attributes, and relationships. Data modeling is used to standardize and communicate an organization's data requirements and establish business rules.
This document provides an overview of databases and database management systems (DBMS). It discusses how databases evolved from file systems to address flaws in data management. It describes what a DBMS is and its functions in managing the database structure and controlling data access. The document also summarizes different database models including hierarchical, network, relational, entity-relationship, and object-oriented models. It highlights advantages and disadvantages of each model.
The document discusses cloud computing, beginning with an explanation of why it is called "cloud" computing based on the visual representation of networks. It then provides definitions of cloud computing, including that it is a model for on-demand access to shared configurable computing resources over a network. The document outlines the essential characteristics of cloud computing including on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It also describes the deployment models of public, private, hybrid, and community clouds and the service models of Infrastructure as a Service, Platform as a Service, and Software as a Service. Advantages include improved performance, reduced costs, unlimited storage, increased reliability, universal access, availability of the latest
This document provides an overview of cloud databases. It defines a cloud database as a database that runs on cloud computing platforms and is accessed as a service. There are two primary methods to run databases in the cloud: using virtual machine images or database-as-a-service (DBaaS). DBaaS allows users to avoid installing and maintaining databases themselves. The document outlines the architecture of cloud databases and characteristics like high availability. It lists advantages such as low cost, easy access to data from anywhere, and simple data sharing. Security issues with cloud databases are also noted.
HTML forms allow users to enter data into a website. There are various form elements like text fields, textareas, dropdowns, radio buttons, checkboxes, and file uploads that collect different types of user input. The <form> tag is used to create a form, which includes form elements and a submit button. Forms submit data to a backend application using GET or POST methods.
This document discusses database design and the database lifecycle (DBLC). It explains that the DBLC involves 6 phases: initial study, design, implementation, testing, operation, and maintenance. The design phase is most critical and involves conceptual, logical, and physical design. Conceptual design uses entity relationship modeling and normalization. Logical design maps the conceptual model to the chosen DBMS. Physical design selects storage structures. The document also discusses top-down vs bottom-up design and centralized vs decentralized design approaches.
HTML Basics document provides an overview of HTML elements and tags used to format text and structure web pages.

This document presents a new algorithm for progressive medical image coding using binary wavelet transforms (BWT). It divides grayscale medical images into binary bit-planes and applies a three-level BWT to each bit-plane. It then encodes each BWT bit-plane using quadtree-based partitioning to exploit the energy concentration in high-frequency subbands. Experiments on ultrasound, MRI and CT images show it provides significant improvements in bitrate for required quality compared to existing progressive image coding methods.

2. 1. Remote Procedure Call (RPC) adalah sebuah metode yang memungkinkan kita untuk
mengakses sebuah prosedur yang berada di komputer lain. Untuk dapat melakukan ini
sebuah server harus menyediakan layanan remote procedure. Pendekatan yang dilakuan
adalah sebuah server membuka socket, lalu menunggu client yang meminta prosedur
yang disediakan oleh server. Bila client tidak tahu harus menghubungi port yang mana,
client bisa me- request kepada sebuah matchmaker pada sebuah RPC port yang tetap.
Matchmaker akan memberikan port apa yang digunakan oleh prosedur yang diminta
client.
RPC masih menggunakan cara primitif dalam pemrograman, yaitu menggunakan
paradigma procedural programming. Hal itu membuat kita sulit ketika menyediakan
banyak remote procedure. RPC menggunakan socket untuk berkomunikasi dengan proses
lainnya. Pada sistem seperti SUN, RPC secara default sudah ter- install kedalam
sistemnya, biasanya RPC ini digunakan untuk administrasi sistem. Sehingga seorang
administrator jaringan dapat mengakses sistemnya dan mengelola sistemnya dari mana
saja, selama sistemnya terhubung ke jaringan.
Umumnya protokol RPC yang digunakan pada saat ini adalah DCOM (Distributed
Component Object Model). Saat ini ada alternatif protokol baru, yakni SOAP (Simple
Object Access Protocol), yang berdasarkan pada teknologi XML.
2. SOAP (Simple Object Access Protocol) adalah standar untuk bertukar pesan-pesan
berbasis XML melalui jaringan komputer atau sebuah jalan untuk program yang berjalan
pada suatu sistem operasi (OS) untuk berkomunikasi dengan program pada OS yang
sama maupun berbeda dengan menggunakan HTTP dan XML sebagai mekanisme untuk
pertukaran data.
SOAP menspesifikan secara jelas bagaimana cara untuk meng-encode header HHTP dan
file XML sehingga program pada suatu komputer dapat memanggil program pada pada
komputer lain dan mengirimkan informasi, dan bagaimana program yang dipanggil
memberikan tanggapan.
SOAP adalah protokol ringan yang ditujukan untuk pertukaran informasi struktur pada
lingkup desentralisasi, dan terdistribusi. SOAP menggunakan teknologi XML utuk
mendefinisikan rangka kerja pemesanan terekstrensi di mana menyediakan konstruksi
pesan yang dapat dipertukarkan pada protokol berbeda. Rangka kerja dirancang bebas
dari model pemrograman dan spesifikasi implementasi semantik.
3. REST, singkatan bahasa Inggris dari representational state transfer atau transfer
keadaan representasi, adalah suatu gaya arsitektur perangkat lunak untuk untuk
pendistibusian sistem hipermedia seperti WWW. Istilah ini diperkenalkan pertama kali
pada tahun 2000 pada disertasi doktoral Roy Fielding, salah seorang penulis utama
spesifikasi HTTP. Istilah ini selanjutnya dipergunakan secara luas pada komunitas
jaringan. REST secara spesifik merujuk pada suatu koleksi prinsip-prinsip arsitektur
jaringan yang menggariskan pendefinisian dan pengalamatan sumber daya. Istilah ini
sering digunakan dengan longgar untuk mendeskripsikan semua antarmuka sederhana
3. yang menyampaikan data dalam domain spesifik melalui HTTP tanpa tambahan lapisan
pesan seperti SOAP atau pelacakan sesi menggunakan cookie HTTP. Dua pengertian ini
dapat menimbulkan konflik dan juga tumpang tindih. Dimungkinkan untuk merancang
suatu sistem perangkat lunak besar sesuai dengan gaya arsitektur REST Fielding tanpa
menggunakan HTTP dan tanpa berinteraksi dengan WWW. Juga dimungkinkan untuk
merancang antarmuka XML+HTTP sederhana yang tidak mengikuti prinsip-prinsip
REST, tapi sebaliknya mengikuti model dari RPC (remote procedure call). Perbedaan
penggunaan istilah REST ini cukup menyebabkan permasalahan dalam diskusi-diskusi
teknis.Sistem yang mengikuti prinsip REST Fielding sering disebut sebagai "RESTful".
