what does "self-executable" mean?

Question

Specifically how could a database be self-executable?

Answer 1

It means that the file execute a fonction without the need for you to do anything. It does it automatically.

Answer 2

It's not a phrase I've heard used in conjunction with databases. Some databases like MS Access require a Runtime Environment. That means the database can't work unless MS Access or the runtime package exists. For example, if you gave me a copy of your Access database, I couldn't use it because I don't have Access. I use a program called Clarion and it creates an EXE file along with the database. If I sent you one of my databases and the exe file, you could run it on any computer whether you had Clarion or not. I guess that's "self executing". Filemaker requires a runtime environment as far as I know, but Delphi doesn't. MySQL does. It's runtime environment is a script written in something like PHP.

Answer 3

Executable compression is any means of compressing an executable file and combining the compressed data with the decompression code it needs into a single executable.



Running a compressed executable essentially unpacks the original executable code, then transfers control to it. The effect is the same as if the original uncompressed executable had been run, so compressed and uncompressed executables are indistinguishable to the casual user.



A compressed executable is one variety of self-extracting archive, where compressed data is packaged along with the relevant decompression code in an executable file.



There are tools that will decompress a compressed executable without executing it, such as CUP386 and UNP.



Most packed executables decompress directly into the memory and need no free file system space to start. However, some decompressor stubs are known to write the uncompressed executable to the file system in order to start it.



I hope it helps!

Answer 4

i think that databases are Typ-4 and can connected direktly from programms via lib without any help from Database Management Servers

Answer 5

I can excute itself.
