Zusammenfassung:To provide an information processing apparatus, an incorporated device, an information processing method, and a program capable of enabling the incorporated device to suitably perform database processing.SOLUTION: An information processing apparatus according to an embodiment has a first generation unit and an evaluation unit. The first generation unit generates an implementation plan that defines rules of data source search processing in a first language based on a group of queries. The evaluation unit derives an evaluation value indicating the degree of performance improvement when at least a part of the implementation plan is converted into a second language that is light in interpretation load compared to the first language.SELECTED DRAWING: Figure 1 【課題】組込機器におけるデータベース処理を好適に行わせることができる情報処理装置、組込機器、情報処理方法、およびプログラムを提供することである。【解決手段】実施形態の情報処理装置は、第1生成部と、評価部とを持つ。第1生成部は、一群のクエリに基づいて、データソースの検索処理の規則を、第1言語によって規定する、実行計画を生成する。評価部は、前記実行計画の少なくとも一部を、前記第1言語よりも解釈負荷が小さい第2言語に変換した際の性能向上度合を示す評価値を導出する。【選択図】図1
