1 1. Suppose we have a (assume relational) source table Product_Id Month Sales 1 Jan x 1 Feb x . . . . . . 1

5.

Dec x 2 Jan x 2 Feb x . . . . . . 2 Dec x 3 Jan x 3 Feb x . . . . . . 3 Dec x . . . . . . and so on. Assume that there could be any number of product keys and for each product key the sales figures (denoted by 'x' are stored for each of the 12 months from Jan to Dec). So we want the result in the target table in the following form. Product_id Jan Feb March.. Dec 1 x x x x 2 x x x x 3 x x x x . . So how will you design the ETL mapping for this case, explain in terms of transformations. What is a candidate key? Data is passed from one active Trans and one passive Trans into a passive Transformation. Is the mapping valid or invalid? What will happen if we have a filter transformation used in a mapping and in the filter condition we specify 1. Yes nothing else, only the number 1. In other words, assuming we have 10 rows coming to this filter transformation as an input, how many rows will be Output by this transformation when we have only 1 in the filter condition? What is shortcut in informatica? Difference between shortcuts, reusable object? 34

20. How can we load the normalised data ( Vertical data) to (Horizontal data)with out using decode in the expression transformation and the aggregator transformation. But, what exactly I want is .. If we have million of records, it is not possible using decode and search for that Particular Id to pivot into Horizontal data... Can any one of guys please help me in this regard..... I want to run a informatica worklow after complition of oracle procedure. That procedure is not running through informatica and can be run at any time in database. Informatica is in windows environment. Is it possible ? If yes please explain.

22. Please let me know how we can implement the below scenario. In a single mapping, more than 500 sources (legacy,VSAM,relational) will be loading into only one target. Whenever I retreive the data(any record) from target, I need to find the details that the record belongs to which source. Thanks in advance..

Than plz help me (i have any exprience of 3yrs informatica,datawarehousing,oracle,teradata) 1.hw the procedure will b here 2. wht type of question's they will b asking. 3.In which area they concertate more. since this is the first time im facing interview in UK. plz help ASAP.it will b a great help for me thanks to All in Advance 248. difference between stop and abort 249. hw cn v elimate dublicate values from lookup without overriding sql? 250. hw to load this give the mapping? cty state o/p c1 s1 c1 c1 s2 s1 c1 s1 c1 c2 s3 s2 c3 s4 c1 c3 s2 s1 c2 s3 c3 s4 c3 s2 2 columns should be loaded to one column in target table? 251. can v update d records in target using update stargey without generationg primary key ? explain

252. suppose if we have dublicate records in a table temp n now i want to pass unique values to t1 n dublicat values to t2 in single mapping?how 253. how do u use sequence created in oracle in informatica? Explain with an simple example 254. supose if ur scr table contains alphanumeric values like 1,2,3,a,v,c in one columen like c1 n now u have load d data in 2 seperare columns like ID should contain only numbers 1,2,3 n NAME col should contain a,b,cin target?How 255. what is metadata? 256. what is dimension table? 257. what is fact table? 258. Which kind of index is preferred in DWH? 259. whether Sequence generater T/r uses Caches? then what type of Cache it is 260. what is shared Cache. when we will use shared Cache? 261. explain different types of modeling. 262. how u know when to use a static cache and dynamic cache in lookup transformation. 263. Explain about HLD and LLD ? 264. for ex: in source 10 records are there with column sal. use a filter transformation condition as Sal=TRUE and connect to target. what will happen. 265. what is tha tracesing level? and difference betweentrace in normal and verbose and nonverbose? 266. i have flatfile source. i want to load the maximum salary of each deptno into target. what isthe mapping flow 267. how much memory (size) occupied by a session at runtime 268. how DTM buffer size and buffer block size are related 269. i have f;latfile source. i have two targets t1,t2. i want to load the odd no.of records into t1 and even no.of recordds into t2. what is the procedure and whar t/r's are involved and what is the mapping flow 270. why cant we put a sequence generator or upd strategy transformation before joiner transformation?

10 271. In Real Time what are the scenarios u faced, what r the tough situations u have overcome, and explain about sessions. 272. Plz can anybody send Informatica and Cognos FAQ Plz To thid ID [email protected] 273. Plz can anybody send Informatica and Cognos FAQ Plz To thid ID [email protected] (or) [email protected] 274. What is difference between Informatica 6.2 Workflow and Informatica Workflow 7.1 275. What is a diff between joiner and lookup transformation 276. what is casual dimension? 277. Without using any transformations how u can load the data into target? 278. Whatis the difference between View and Materialized View ? 279. lz can anybody send Informatica and Cognos FAQ Plz To thid ID [email protected] 280. we have table like cust_id,cust_name,cust_loc like this 1.we need to get perticular location,to do this we can use filter transformatin,that logic is same for relation table and flat file tabl? 281. 1.why we need to use unconnected transformation? 2.where we can static chach,dynamic chach

282. What is incremental aggregation and how it is done? 283. How could we generate the sequence of key values without using sequence generator transformation in the target ?? 284. How do we come to know the Source data/file is ready/Updated in the source location, when the session is scheduled for @12:00AM and ready to run its job ? or Can we schedule the session, when the source is updated in source location without any time constraint? 285. how do u move the code from development to production? 286. In a scenario I have col1, col2, col3, under that 1,x,y, and 2,a,b and I want in this form col1, col2 and 1,x and 1,y and 2,a and 2,b, what is the procedure? 287. On a day, I load 10 rows in my target and on next day if I get 10 more rows to be added to my target out of which 5 are updated rows how can I send them to target? How can I insert and update the record? 288. What is the method of loading 5 flat files of having same structure to a single target and which transformations I can use? 289. In a scenario I want to change the dimensions of a table and normalize the denomralized table which transformation can I use?

290. Why is meant by direct and indirect loading options in sessions?

291. what is the logic will you implement to load data into a fact table from n dimension tables? 292. I have 1200 records how can u send it in aggregator with good performance issues? 2634

293. Flat file heaving 1 lack records and I want to push 52000 records to the target? 294. How will u pas the data with out debugger? 295. How will u find weather dimension table is big in size of a fact table? 296. In router source is a boy age 20 I given 3 conditions in router a>20, a
