How to analyze binary file?

I have a binary file. I don't know how it's formatted, I only know it comes from a delphi code.

Does it exist any way to analyze a binary file?

Does it exist any "pattern" to analyze and deserialize the binary content of a file with unknown format?

Try these:

1. Deserialize data: analyze how it's compiled your exe (try File Analyzer). Try to deserialize the binary data with the language discovered. Then serialize it in a xml format (language-indipendent) that every programming language can understand
2. Analyze the binary data: try to save various versions of the file with little variation and use a diff program to analyze the meaning of every bit with an hex editor. Use it in conjunction with binary hacking techniques (like How to crack a Binary File Format by Frans Faase)
3. Reverse Engineer the application: try getting code using reverse engineering tools for the programming language used for build the app (found with File Analyzer). Otherwise use disassembler analysis tool like IDA Pro Disassembler
