How to use MySQL to create an scalable accounting system table structure to cope with business growth and changes?
In today's increasingly developing business environment, accounting systems play a vital role in enterprises. As business grows and changes, a scalable accounting system table structure can help companies effectively manage and track financial data and ensure the smooth operation of financial processes. This article will introduce how to use a MySQL database to create a scalable accounting system table structure and give specific code examples.
First of all, we need to clarify the basic concepts and requirements of the accounting system. A complete accounting system contains many important financial concepts, such as accounts, subjects, vouchers, etc. The following is an example of a simplified accounting system table structure:
Accounts table (accounts)
Chart of accounts (categories)
Vouchers table (vouchers )
CREATE TABLE accounts ( account_id INT PRIMARY KEY, account_name VARCHAR(100) NOT NULL, account_type VARCHAR(50) NOT NULL, balance DECIMAL(10, 2) );
CREATE TABLE categories ( category_id INT PRIMARY KEY, category_name VARCHAR(100) NOT NULL, parent_category_id INT );
CREATE TABLE vouchers ( voucher_id INT PRIMARY KEY, voucher_date DATE NOT NULL );
CREATE TABLE voucher_items ( item_id INT PRIMARY KEY, voucher_id INT, category_id INT, debit DECIMAL(10, 2), credit DECIMAL(10, 2), FOREIGN KEY (voucher_id) REFERENCES vouchers(voucher_id), FOREIGN KEY (category_id) REFERENCES categories(category_id) );
ALTER TABLE accounts ADD UNIQUE INDEX account_name_unique (account_name);
CREATE TRIGGER update_balance AFTER INSERT ON voucher_items FOR EACH ROW BEGIN UPDATE accounts SET balance = balance + NEW.debit - NEW.credit WHERE account_id = (SELECT category_id FROM voucher_items WHERE item_id = NEW.item_id); END;
