[¶ 1] Walter Johnson appeals from a judgment entered in the Superior Court (Cumberland County, Brennan, J.) granting Samson Construction’s motion for a summary judgment. Johnson argues on appeal that the court erred in its determination that res judicata bars his suit. We disagree and affirm the judgment.
I.
[¶ 2] In June 1988 Samson Construction executed and dеlivered to Johnson a promissory note for $69,500 and a mortgage deed. The note required principal and interest to be paid in 240 equal monthly installmеnts, and it contained the following acceleration provision: “If any default be made in any payment under this Note, and if such default is not made good within thirty (30) days after written notice of same, the entire unpaid principal and accrued interest shall become *868 immediately due and payable without further demand.”
[¶3] After Samson defaulted on its May 1990 payment and failed to cure, Johnson initiated a foreclosure action against Samson in August 1990, seeking a judgment against Samson “for the amount due under the Note.” Four years later the court entered an order dismissing Johnson’s suit with prejudice unless he filed the Report of Conference of Counsel within ten dаys. Johnson did not file the report, and the court dismissed Johnson’s action with prejudice on December 1, 1994.
[¶ 4] In August 1995 Johnson initiated the present action, alleging a failure to make any payment on the note since September 1990 and again seeking a judgment “for the amount due under the Note.” Samson movеd for a summary judgment, arguing that Johnson’s complaint was barred by res judicata. Johnson contended that dismissal of the prior case was res judicata оnly with regard to any default that occurred before the filing of the prior complaint, but was not a bar to a claim based upon any default which may have occurred after the filing of the prior complaint. Noting that “in the prior case ... the Plaintiff alleged that the Note had been acсelerated and that the Plaintiff was seeking the entire balance due under the Note,” the court found that the dismissal with prejudice of the prior aсtion barred the instant suit and granted a summary judgment to Samson. This appeal followed.
II.
[¶ 5] A party is entitled to a summary judgment if no genuine issue of material fact exists and if the party is entitled to a judgment as a matter of law.
Seashore Performing Arts Ctr., Inc. v. Town of Old Orchard Beach,
[¶ 6] “The doctrine of res judicata. ‘is a court-made collection of rules designed to ensure that the same matter will not be litigated more than once.’”
Machias Sav. Bank v. Ramsdell,
the measure of a cause of action is the aggregate of connected operative facts that can be handled together conveniently for purposes of trial. A prior judgment bars а later suit arising out [of] the same aggregate of operative facts even though the second suit relies on a legal theory not advanced in the first case, seeks different relief than that sought in the first case, and involves evidence different from the evidence relevant to the first case.

[¶7] A plaintiff may not split a cause of action and prosecute each of its parts in separate lawsuits.
Kradoska v. Kipp,
[¶ 8] The promissory note between Johnson and Samson required 240 equal monthly payments of principal and interest. However, the note’s acceleration clause provided that “[i]f any default be made in any payment under this Note, and if such default is not made good within thirty (30) days after written notice of same,
the entire unpaid principal and accrued interest shall become immediately due and payable without further demand.”
(emphasis added). Johnsоn’s first cause of action alleged that Samson “defaulted on its obligations to the Plaintiff under the Note” and demanded payment of the entire unpaid principal balance. This suit was an action for the accelerated debt. Once Johnson triggered the acceleration clausе of the note and the entire debt became due, the contract became indivisible. The obligations to pay each installment merged into one obligation to pay the entire balance on the note.

The entry is:
Judgment affirmed.
Notes
. Johnson argues that if the dismissal with prejudice of his first suit bars a subsequent action on the note, Samson will receive a windfall. Such a windfall may occur in any case in which a parly defaults on a procedural obligation.
