Is "integrate against" a proper verb+preposition combination?

One of my colleague keeps using "integrate against" as in the following sentence:

The component A is integrated against the platform B.

Google search shows several hundreds of the form. As far as I know, however, "integrate" is typically used along with the preposition "with" or "into".

Could someone guide me on what is the correct usage? If "against" can be used, in what context is it proper?

Thank you.

Solution 1:

In mathematics, to integrate A against B means to perform the computation ∫ A dB or, occasionally, ∫ A B. In the usual English sense of the word integrate meaning to combine objects A and B, however, it is exclusively used with the prepositions with and into (see here, for example). I think your colleague has heard integrate against in the mathematical usage and has mistakenly assumed it to share the usual English meaning.
