The development of interactive websites cannot be separated from the support of databases. So, what is a database? Simply put, a database (DataBase, DB) is an organized, shared collection of data that is centrally managed and stored long-term within a computer system. In more common terms, a database is a warehouse for organizing, storing, and managing data according to data structures. In today's internet enterprise website operations, databases are increasingly becoming valuable tools for IT administrators. The types of databases are also diversifying, gradually permeating into various fields. Below are seven commonly used types of databases in enterprise website construction:
1. **Access Database Used in Changchun Website Construction**
Access is a relational database management system released by Microsoft, launched in 1994. It combines the features of the Microsoft Jet Database Engine and a graphical user interface. Additionally, it has characteristics such as user-friendly interfaces, ease of learning and use, simple development, and flexible interfaces, making it a typical next-generation desktop database management system. Furthermore, Access is also the name of a C language function and a type of switch trunk pattern.
2. **MySQL Database Used in Changchun Website Construction**
MySQL is a small-scale relational database management system developed by the Swedish company MySQL AB, which was acquired by Sun Microsystems in 2008. MySQL is widely used on medium and small-sized websites on the Internet. Due to its small size, fast speed, low total cost of ownership, and especially its open-source nature, many medium and small websites choose MySQL as their website database to reduce overall costs. Virtual hosting with Unix standard adopts the MySQL database.
3. **SQL Server Database Used in Changchun Website Construction**
SQL (Structured Query Language) is primarily used to establish communication with various databases. SQL statements can perform a wide variety of operations. Most popular relational database management systems adopt the SQL language standard. Although many databases redevelop and extend SQL statements, standard SQL commands such as Select, Insert, Update, Delete, Create, and Drop can still be used to complete almost all database operations.
4. **Oracle Database Used in Changchun Website Construction**
Oracle is a world-leading information management software developer renowned for its complex relational database products. Oracle database products are used by the top 1000 companies on the Fortune list, and many large websites have also chosen the Oracle system. Oracle's relational database targets high-end workstations and minicomputers as servers. Oracle’s database is the world's first database to support the SQL language.
5. **DB2 Database Used in Changchun Website Construction**
DB2 is a relational database management system developed by IBM. DB2 is mainly applied in large application systems, with good scalability, supporting environments ranging from mainframes to single-user setups, and applicable under platforms like OS/2 and Windows. It is well-known for having a very comprehensive query optimizer. DB2 has excellent network support capabilities, with each subsystem able to connect to hundreds of thousands of distributed users and activate thousands of active threads simultaneously, making it particularly suitable for large distributed application systems.
6. **FoxPro**
Originally named FoxBase, Visual FoxPro was initially launched in 1988 by the American company Fox Software as a database product running on DOS and compatible with the xBase series. It was acquired by Microsoft in 1992, leading to subsequent releases like FoxPro 2.5, 2.6, and Visual FoxPro. Compared to FoxBASE, FoxPro significantly improved in functionality and performance, mainly through the introduction of controls such as windows, buttons, list boxes, and text boxes, further enhancing the system's development capabilities.
7. **Informix**
Informix is a family of relational database management systems (RDBMS) produced by IBM. Founded in 1990, its purpose was to provide professional relational databases for open operating systems such as Unix. Informix SE was one of the primary database products in the microcomputer Unix environment at the time. It was also the first commercial database product to be ported to Linux.
