English term or phrase: structure of the sentence
The overall functional structure of the Network Manager database is shown in Figure 4. The primary data flow in the system is from the RTU point database to the Remote Terminal Unit Communication Server (RCS) point database, and then to the point data area in the Network Manager Avanti database. The data flow related to device control goes in the opposite direction. The processing of the point data is controlled by data structures that contain RCS and RTU control information, event handling definitions, and calculation definitions. Additional control data structures in the time-tagged data area of the database define how point data is periodically accessed, processed, and stored there as time-tagged data.
References between the point data and these control data structures link specific data with specific processing and storage definitions. ***Data maintenance utilities are used to define and modify these references, and the control data structures themselves, to specify the basic data handling and processing functionality of a Network Manager system.***

Please help understand the structure of the sentence. Am I right in guessing that what they mean here is that "data maintenance utilities are used to define and modify", while "control data structures" are used "to specify the basic data handling and processing functionality"?
Or should it be understood like, "data maintenance utilities are used to define and modify the references AND the control data structures", and also "to specify the basic data handling and processing functionality"?
Thank you.

Selected answer:Your second proposition is closest
Explanation:
"data maintenance utilities are used to define and modify the references AND the control data structures"

and the purpose of doing this is
"[in order] to specify the basic data handling and processing functionality"

The clue to this interpretation is the inclusion of 'themselves', which clearly separates 'control data structures' from the clause that follows.

agree  Jack Doughty: But it is ambiguous. I was about to submit a contrary answer, but on reading it again, I realised you are right.
31 mins
  -> Thanks, Jack! I think the fact that the 'and... themselves' clause is a parenthesis really clears that ambiguity; where it not, then I agree, it wouldn't be clear.

agree  Charles Davis: Without properly understanding the substance of this, I clearly read it your way, partly for the reason you mention, but also because of the comma after themselves, which, to me, rules out the alternative (I suppose this is your point about parenthesis).
2 hrs
  -> Thanks, Charles! Yes, exactly: if you leave out the clause in parenthesis, it makes sense, and could not logically be parsed any other way. The use of 'themselves' "gets in the way"!

neutral  B D Finch: But shouldn't it read "... as well as to specify the basic data handling ..."? Doesn't that omission does leave a question mark over whether the commas have been used correctly?
12 hrs
  -> Thanks, B! To me, the commas (assuming used correctly!) make it clear that these are 2 different applications of 'to', with the implicit sens of 'in order to' as I have suggested; but Robin has an alternative interpretation, assuming a S/T error.

neutral  Jennifer Levey: This interpretation is extremely unlikely to be correct, from a purely technical viewpoint.
12 hrs
  -> Thanks, Robin! I understand what you are saying, but am not qualified to comment further on that point.

agree  Katalin Horváth McClure: This is the right interpretation, the comma after "references" should not be there, and indeed, "to specify" is meant as "in order to specify". This makes sense from the technical point of view as well.

Explanation:
The sentence is grammatically ambiguous, but clear in context (and with an understanding of the technicalities involved here).

It would be unambiguous – and correct – if it has been written thus:

Data maintenance utilities are used to define and modify these references, WHILE the control data structures (delete: themselves, to) specify the basic data handling and processing functionality of a Network Manager system.

This interpretation is confirmed, technically, by the fact that the periodic “accessing, processing and storage” of the point data in the sentence: “Additional control data structures in the time-tagged data area of the database define how point data is periodically accessed, processed, and stored there as time-tagged data”, are all part of the “basic data handling” referred to in the last sentence of the first paragraph where the overall purpose of the control data structures is stated.

Also from a technical standpoint, it would be unusual for a “control data structure” to be “defined and modified” at run-time.

neutral  Tony M: I see the technical logic of what you're suggesting — but it requires the assumption of a pretty whopping s/t error, in what appears otherwise to be a quite well written text. Would require an impliict 'are used ...' after 'elsewhere', which is possible.
7 hrs
  -> A technical text which is ambiguous can never be regarded as "quite well written". And in technical texts, logic must prevail over bad punctuation. In any case, my proposed re-writing is only to illustrate the meaning - the ST is sloppy, not 'wrong'.

neutral  Katalin Horváth McClure: I don't think so. The text does not say the utilities are modifying anything at runtime. The role of the references should not be forgotten when we try to decipher this. The data structures themselves are not enough to specify the functionality.
