Stuck in a snowstorm, he came up with the idea to store large, unstructured data in a database. The name was inspired by the 1958 movie&nbsp;<em>The Blob<\/em>. Over time, the term evolved into an acronym: Binary Large Object.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fun_Fact\"><\/span><strong>\u6709\u8da3\u7684\u4e8b\u5b9e<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Initially, some developers disliked the term &#8220;BLOB&#8221; because it sounded unprofessional. Alternative names like &#8220;segmented strings&#8221; were proposed, but &#8220;BLOB&#8221; stuck around and became widely accepted.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Challenges_of_Using_BLOBs\"><\/span><strong>Challenges of Using BLOBs<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>While BLOBs are incredibly useful, they come with their own set of challenges:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Storage Costs<\/strong>: Storing large files directly in a database can be expensive.<\/li>\n\n\n\n<li><strong>Performance Issues<\/strong>: Retrieving BLOBs can slow down database performance if not managed properly.<\/li>\n\n\n\n<li><strong>Complexity<\/strong>: Handling BLOBs requires specialized knowledge and tools.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Workaround\"><\/span><strong>Workaround<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>To address these issues, many systems store BLOBs in external storage solutions, linking them to the database with unique identifiers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Other_Fields_Where_BLOB_is_Used\"><\/span><strong>Other Fields Where BLOB is Used<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>BLOB isn\u2019t just a tech term.
