<prompt> Litsela tse tharo tsa ho boloka data ea maemo a phahameng ka hara database ke life?nan  <response>: Instruction in English: What are three ways to store hierarchical data in a database? . Response in English: There are several ways to store hierarchical data in a database, and here are three common methods:1. Adjacency List: This model uses a parent-child relationship to store hierarchical data. The parent id is stored as a property of the child row. It is simple to implement and easy to understand, but it can be difficult to retrieve data that is nested several levels deep.2. Nested Set: This method uses the concepts of left and right values to represent the hierarchical relationships between rows. The left and right values of a node represent the range of its descendant nodes. This model can retrieve entire subtrees with a single query, but it can be complex to implement and update.3. Closure Table: This method stores all possible relationships between nodes in a separate table. Each row in the closure table represents an ancestor-descendant relationship, with additional columns for depth and other attributes. This model allows for fast retrieval of hierarchical data, and easy updates and inserts, but it requires more storage space due to the additional table. . Response in Sesotho: Ho na le mekhoa e maloa ea ho boloka boitsebiso ba maemo a phahameng ka hara polokelo ea boitsebiso, me mekhoa e meraro e tloaelehileng ke ena: 1. Lethathamo la Likamano tsa Botho: Moetso ona o sebelisa kamano ea motsoali le ngoana ho boloka boitsebiso ba maemo. Id ea motsoali e bolokiloe e le thepa ea mola oa ngoana. Ho bonolo ho e kenya tsebetsong ebile ho bonolo ho e utloisisa, empa ho ka ba thata ho fumana lintlha tse fumanehang maemong a maloa ka botebo. 2. Nested Set: Mokhoa ona o sebelisa likhopolo tsa leqele le le letona ho emela likamano tsa maemo a phahameng lipakeng tsa mela. Litekanyetso tse ka ho le letšehali le tse nepahetseng tsa node li emela mefuta e mengata ea li-node tsa eona. Moetso ona o ka fumana li-subtrees kaofela ka potso e le ngoe, empa ho ka ba thata ho kenya tsebetsong le ho ntlafatsa. 3. Letlapa la ho Koala: Mokhoa ona o boloka likamano tsohle tse ka bang teng lipakeng tsa li-node tafoleng e arohaneng. Mola o mong le o mong oa tafole ea ho koala o emela kamano ea litloholo tsa balimo, e nang le litšiea tse eketsehileng bakeng sa botebo le litšobotsi tse ling. Mohlala ona o lumella ho khutlisetsoa ka potlako ha data ea hierarchical, le lisebelisoa tse bonolo le ho kenya, empa ho hloka sebaka se eketsehileng sa polokelo ka lebaka la tafole e eketsehileng.
