change some Delphi DB code

a large application is written in Delphi 5 and uses IBObjects to connect to a Firebird 1.5 database. In order to make the code faster, we want to experiment a new way to display the needed data from the DB. The idea is to load large chunks of data (possibly a whole table) into memory using TEasyTable and to query data from the in-memory table using TEasyQuery. Both components are available in trial version at [[login to view URL]][1]. In the attached form [login to view URL], you will find the 3 queries that are often issued and should be made faster. Please read the queries inside procedures: procedure ediWorkEnter(Sender: TObject); procedure ediVesselEnter(Sender: TObject); procedure ediOrderEnter(Sender: TObject); Here procedure ediVesselEnter(Sender: TObject); is the slowest of the 3. The idea is to load tables tb_wrk (98 records) tb_ves (75,000 records) tb_cst (42,000 records) a_ord (138,000 records) into memory once at start time and query the in-memory tables every time it is needed. These tables are changed only once a day (updating data from a central server). The coder will deliver a text EXE that shows the improved results. For what I know, the same result can be achieved by using TClientDataset. I could accept that solution, too (or any equivalent path other than using TEasyTable). Please specify the road you intend to take. The selected coder can get a full db (if needed). ## Deliverables req4 is meant to give you an idea of what has to be done. It won't compile. [login to view URL] is a database, with no SP or trigger. Only SP VALIDITYELAPSEDBIS is included for your reference.
