The storage capacity of Oracle database depends on hardware limitations, disk space, memory, data block size, table space, indexes, data types, compression and other factors. Generally speaking, large enterprise databases can store terabytes or even petabytes of data, while small business or personal databases may only have a few hundred gigabytes or less of data.
Oracle database storage capacity
Oracle database can theoretically store huge amounts of data. The specific storage capacity depends on the following factors:
Hardware limitations
- Disk space: Oracle database stores data on physical disks. Available disk space determines the maximum storage capacity of the database.
- Memory: Sufficient memory can improve database performance, allowing for larger database sizes.
Database configuration
- Data block size: Data block is the basic unit for database storage of data. Larger data blocks improve storage efficiency by reducing block management overhead.
- Table space: Table space is a logical storage unit used to organize and manage data. Proper table space design can optimize storage usage.
- Index: Index is a data structure that optimizes data retrieval. Proper indexing can reduce data storage space.
Data types and compression
- Data types: Different data types occupy different storage spaces. For example, numeric data types are generally more compact than character data types.
- Compression: Compression technology can reduce data storage space without affecting data integrity.
Actual Value
Depending on the above factors, the actual storage capacity of an Oracle database may vary from hundreds of GB to petabytes.
Example
- Large enterprise database: Large enterprise databases can often store terabytes or even petabytes of data.
- Small Business Database: A small business database may only have a few hundred gigabytes of data.
- Personal Database: Oracle databases used for personal use typically have only a few GB or less of data.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
