- Data<\/strong>: stored values or information (eg. name, date, transaction).<\/li>\n\n\n\n
- Schema<\/strong>: a structure that describes how data is organized (tables, columns, relations).<\/li>\n\n\n\n
- DBMS<\/strong>: software that manages databases (eg. MySQL, PostgreSQL, MongoDB).<\/li>\n\n\n\n

Differences with regular spreadsheets and files<\/h3>\n\n\n\n
Spreadsheets like Excel are suitable for small data and simple analysis, but they are not designed to handle large-scale concurrent access, atomic transactions, or complex integrity assurance. Databases provide a more robust mechanism for consistency, security, and scalability.<\/p>\n\n\n\n
Types of databases<\/h2>\n\n\n\n
1. Relational Database (SQL)<\/h3>\n\n\n\n
Relational databases store data in tables with rows and columns. Relationships between tables are defined through primary and foreign keys. Bahasa yang umum digunakan adalah SQL (Structured Query Language). Contoh DBMS relasional: MySQL, PostgreSQL, Oracle. Relational is suitable for applications that require transaction accuracy (eg. banking system, ERP).<\/p>\n\n\n\n
2. Database non-relasional \/ NoSQL<\/h3>\n\n\n\n
NoSQL includes a variety of data models that are not traditionally table-based, such as:<\/p>\n\n\n\n
- \n
- Key-Value<\/strong> (storage of key-value pairs),<\/li>\n\n\n\n
- Documents<\/strong> (JSON\/BSON document storage like MongoDB),<\/li>\n\n\n\n
- Column-width<\/strong> (Cassandra),<\/li>\n\n\n\n
- Graph<\/strong> (Neo4j for complex relations).
NoSQL is often chosen for the need for large scale, schema flexibility, or semi-structured data.<\/li>\n<\/ul>\n\n\n\n3. Object-oriented & multimodel databases<\/h3>\n\n\n\n
Some DBMSs support object-oriented or multimodel paradigms (combining relational and document). This option facilitates integration with applications that use objects or require data model flexibility.<\/p>\n\n\n\n
4. Cloud database & DBaaS<\/h3>\n\n\n\n
Layanan basis data di cloud (Database as a Service\/DBaaS) disediakan oleh penyedia seperti AWS, yang menawarkan kemudahan provisioning, skalabilitas otomatis, dan pengelolaan infrastruktur tanpa perlu mengelola server fisik. Cloud DB makes it easier for organizations to focus on application development over database operations.<\/p>\n\n\n\n
Database functions<\/h2>\n\n\n\n
1. Storing and organizing data<\/h3>\n\n\n\n
Databases provide a structure for storing data in an organized manner so that it is easy to search and manage.<\/p>\n\n\n\n
2. Ensure data integrity and consistency<\/h3>\n\n\n\n
With schema rules, constraints, and transactions, databases keep data valid and consistent despite many parallel operations.<\/p>\n\n\n\n
3. Supports transactions and concurrency<\/h3>\n\n\n\n
The Database supports atomic operations (all transactions succeed or fail), isolation between transactions, as well as locking or multi-versioning mechanisms for concurrent access.<\/p>\n\n\n\n
4. Security and access control<\/h3>\n\n\n\n
DBMS provides authentication, authorization, encryption, and auditing to protect sensitive data.<\/p>\n\n\n\n
5. Analytics and reporting<\/h3>\n\n\n\n
Databases (especially data warehouses) enable analytical, aggregation, and reporting processes that support business decision making.<\/p>\n\n\n\n
Examples of databases in real life<\/h2>\n\n\n\n
A. Examples on Business<\/h3>\n\n\n\n
- \n
- Inventory system<\/strong>: store stock data, suppliers, and transaction history.<\/li>\n\n\n\n
- CRM (Customer Relationship Management)<\/strong>: store customer, interaction, and lead data.<\/li>\n\n\n\n
- E-commerce<\/strong>: product catalog, orders, payments, and customer history.<\/li>\n<\/ul>\n\n\n\n
B. Examples on Government & Public Service<\/h3>\n\n\n\n
- \n
- Population databases, tax systems, electronic medical records \u2014 they all require integrity, security and high availability.<\/li>\n<\/ul>\n\n\n\n
C. Examples on everyday applications<\/h3>\n\n\n\n
- \n
- Messaging apps store user lists and message histories; streaming platforms Store content metadata and user preferences.<\/li>\n<\/ul>\n\n\n\t\t\r\n\t\t\t\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t

1. Examples of simple relational models<\/h3>\n\n\n\n
Suppose a small online store has three tables:
users<\/code>,products<\/code>,orders<\/code>.<\/p>\n\n\n\nExamples of short schemes:<\/p>\n\n\n\n
CREATE TABLE users ( id INT PRIMARY KEY, name VARCHAR(100), email VARCHAR(100) UNIQUE ); CREATE TABLE products ( id INT PRIMARY KEY, name VARCHAR(150), price DECIMAL(10,2) ); CREATE TABLE orders ( id INT PRIMARY KEY, user_id INT, product_id INT, qty INT, order_date DATE, FOREIGN KEY (user_id) REFERENCES users(id), FOREIGN KEY (product_id) REFERENCES products(id) );\n<\/code><\/pre>\n\n\n\nThe above schema shows a simple relationship between customer, product, and order.<\/p>\n\n\n\n
2. NoSQL example (JSON document)<\/h3>\n\n\n\n
Product document example in MongoDB:<\/p>\n\n\n\n
{\n \"_id\": \"p001\",\n \"name\": \"Kemeja Katun\",\n \"price\": 199000,\n \"variants\": [\n {\"size\": \"M\", \"stock\": 10},\n {\"size\": \"L\", \"stock\": 5}\n ],\n \"tags\": [\"fashion\",\"kemeja\",\"katun\"]\n}\n<\/code><\/pre>\n\n\n\nThe document Model makes it easy to store varied attributes without a rigid schema.<\/p>\n\n\n\n

FAQ About Database<\/em><\/h2>\n\n\n\n
What is database<\/em>?<\/strong><\/summary>\n
Database<\/em> is a collection of data arranged in an organized way so it is easy to access, manage, and update. It is managed by specialized software called a Database Management System<\/em> (DBMS) that governs storage, integrity, transactions, and user access.<\/p>\n<\/details>\n\n\n\n
What are the main components of a database<\/em>?<\/strong><\/summary>\n
Four components: data in the form of stored values or information, a schema describing the structure of tables, columns, and relations, a DBMS such as MySQL, PostgreSQL, or MongoDB, and hardware and infrastructure in the form of storage servers, networks, and a backup<\/em>.<\/p>\n<\/details>\n\n\n\n
What is the difference between a database<\/em> with a spreadsheet?<\/strong><\/summary>\n
Spreadsheets like Excel suit small data and simple analysis, but are not designed for large-scale concurrent access, atomic transactions, or complex integrity guarantees. A Database<\/em> provides stronger mechanisms for consistency, security, and scalability.<\/p>\n<\/details>\n\n\n\n
What types of database<\/em>?<\/strong><\/summary>\n
Relational (SQL) databases storing data in tables with primary and foreign keys, non-relational or NoSQL databases such as key-value<\/em>, document, wide-column, and graph stores, object-oriented and multimodel databases, plus the cloud database<\/em> a.k.a. DBaaS managed by cloud service providers.<\/p>\n<\/details>\n\n\n\n
What is the function of an database<\/em>?<\/strong><\/summary>\n
Storing and organizing data in a structured way, guaranteeing integrity and consistency through schemas and constraint<\/em>s, supporting transactions and concurrent access, securing data through authentication, encryption, and auditing, and facilitating analytics and reporting for business decision-making.<\/p>\n<\/details>\n\n\n\n
How do you choose the right type of database<\/em> for the job?<\/strong><\/summary>\n
For applications demanding high transactional consistency such as banking, choose a relational database. For unstructured data needing horizontal scale, choose NoSQL. For large-scale analytics and reporting, use a data warehouse<\/em> or an OLAP solution \u2014 while still weighing team capability, operating costs, and availability needs.<\/p>\n<\/details>\n\n\n\n
